Water-Cooled Screw Chiller Basics

How Water-Cooled Screw Chillers Work

A water-cooled screw chiller cools big buildings and factories. It has two main loops. One is the refrigeration loop. The other is the chilled water loop. The refrigeration loop uses the vapor compression cycle. This cycle lets the refrigerant change between liquid and vapor. It helps absorb heat and then release it. The chilled water loop sends cold water to places that need cooling.

Here is how water-cooled chillers work step by step:

1. The screw compressor takes in low-pressure refrigerant vapor. It squeezes the vapor to make it hotter and under more pressure.

2. The condenser moves heat from the refrigerant to the cooling water. The cooling water goes to the cooling tower.

3. The expansion valve drops the pressure and temperature of the refrigerant.

4. The evaporator takes heat from the chilled water. This cools the water for the building or process.

5. The cycle starts again. This keeps cooling steady and efficient.

This process makes water-cooled screw chillers great for keeping temperatures stable in many places.

Key Components

Every water-cooled screw chiller has important parts. These parts work together to keep things cool:

These main parts help water-cooled chillers work well, last long, and stay reliable in tough places.

Energy Efficiency Advantages

Water-cooled screw chillers are very good at saving energy. They use water to move heat. This helps them cool big buildings well. Using water makes them use less energy. It also helps building owners follow green rules. Experts use SEER, EER, and COP to check how well chillers work. These numbers tell us how much cooling comes from the power used. Lower approach temperatures mean the chiller works better.

Variable Speed Drives

Variable speed drives, or VSDs, help chillers save more energy. VSDs let the compressor change speed when needed. This means the chiller does not always run at full power. It uses less energy when cooling needs are low.

• VSDs stop energy waste by slowing the compressor instead of turning it off and on.

• Studies show VSD chillers use about 11% less energy each year than chillers that run at one speed.

• In big buildings, VSDs can save over a million kilowatt-hours every year.

Tip: VSDs make chillers work better and last longer. They also help save money over time.

Advanced Heat Exchangers

Advanced heat exchangers help chillers move heat faster. New designs, like falling-film evaporators and special tubes, use less refrigerant and energy.

• Hybrid evaporators mix old and new ideas for better cooling and less harm to the planet.

• Stronger tube materials stop rust and help move heat better.

• These changes let chillers reach COP values up to 4.98, showing they save a lot of energy.
  Better heat exchangers also make chillers smaller. This saves space and helps them fit in tight spots.

Innovations in Water Cooled Screw Chiller Technology

IoT and Smart Controls

New water-cooled screw chillers use IoT and smart technology. These systems collect data like temperature and humidity. They also track how much work the chiller is doing. Smart controllers use this information to help the chiller work better. This makes the chiller use less energy and run more smoothly.

• Smart controls can cut energy use by half compared to old chillers.

• One factory in Beijing used 25% less energy in a month after adding smart controls.

• These systems watch the equipment and make small changes to keep things working well.

• This means fewer problems and better control of temperature.

Facility managers need to check their systems before adding IoT. They should pick equipment that works with the new tech. Staff must learn how to use the new system. Regular checks and care, like fixing sensors and checking networks, keep things running well. More people want energy-saving and green systems, so smart chillers are becoming popular.

Note: IoT and smart controls are a big step for cooling systems. They help companies save money and have less downtime.

Sustainable Refrigerants

The industry now wants to use sustainable refrigerants to protect the environment. Old refrigerants like R-134a can harm the planet. New rules say companies must use greener choices. The U.S. SNAP program and some states, like California, limit high-GWP refrigerants in new chillers.

• New refrigerants like R-454B, R-1234ze(E), R-1233zd(E), R-513A, R-515B, and R-32 have much lower GWP.

• Some have GWP close to 1, so they are almost climate-neutral.

• These new refrigerants help chillers work better and follow strict rules.

• Most are not flammable or only a little flammable, so they are safer.

• Top companies now sell chillers with these refrigerants to cut carbon without losing performance.

Natural refrigerants like ammonia, CO2, and hydrocarbons have very low GWP. But they can be harder to use because of safety and cost. Using better refrigerants shows how new ideas and rules are changing cooling.

Scroll Compressor Integration

Adding scroll compressors is another big change in water-cooled screw chillers. Now, some chillers use both screw and scroll compressors together. This is called a hybrid system. It uses the best parts of each compressor.

• Scroll compressors are good when the chiller does not need to work as hard.

• Screw compressors are better when the chiller needs to cool more.

• Hybrid chillers can switch between the two or use both, depending on what is needed.

This design helps chillers use less energy and work better. It also makes chillers more reliable. Hybrid chillers can fit many building sizes and uses. These changes help chillers meet new needs and support a greener world.

Tip: Hybrid systems give more choices and save energy. They are a smart pick for new buildings and upgrades.

In busy logistics hubs and warehouses, moving goods efficiently is a top priority. One tool that’s become increasingly important in this process is the telescopic belt conveyor. If you've ever seen a long conveyor sliding in and out of a truck like a giant mechanical arm, you've likely seen one in action. But what exactly is it, and how does it actually work?

Let’s break it down in a way that combines technical understanding with real-world application.

A Simple Definition

At its core, a 4 extension loading and unloading conveyor is a kind of conveyor system that can extend and retract, much like a telescope. This movement allows it to reach inside trucks or containers for easier loading and unloading. The design significantly reduces manual handling, improves safety, and speeds up operations.

In more technical terms, it's a multi-section conveyor where the nested sections slide out to extend the length. The belt moves continuously along these sections, even as the conveyor extends or contracts.

How Does It Work?

Now let’s get into the mechanics—without sounding like a textbook.

Imagine you’ve got a truck backed up to your dock. Instead of sending in workers to carry boxes one by one, you roll up the telescopic conveyor. At the press of a button (or using manual control in simpler models), the conveyor slides forward, reaching deep inside the truck.

The moving belt—usually made from durable rubber or PVC—carries boxes from the vehicle right into the warehouse or the other way around. Some models even let you adjust the height or tilt the conveyor to match different truck sizes or dock levels.

And when the job’s done? Just retract the conveyor back like a telescope and roll it away. Simple, right?

Key Features (from a Practical Viewpoint)

While tech specs matter, most warehouse managers care more about how it helps:

Adjustable length – So you can handle different truck sizes.

Height control – For aligning with containers or dock heights.

One-person operation – Reduces manpower costs.

Fast belt movement – Speeds up loading and unloading dramatically.

Safety mechanisms – Like emergency stop buttons and anti-slip belts.

Where Is It Used?

You’ll find mobile telescopic belt conveyors in a lot of places:

Logistics centers shipping thousands of parcels daily

Online retail fulfillment hubs (think e-commerce giants)

Courier and express parcel services

Airports, for baggage handling

Warehouses and storage facilities

Basically, if there are goods constantly coming in and going out, a telescopic conveyor makes the job smoother.

Why Are Telescopic Belt Conveyors So Popular?

Now, let’s get real. Time is money—and in logistics, wasted time equals wasted revenue. A conveyor that extends into a truck eliminates time-consuming, back-breaking labor. Not to mention, it cuts down the chance of workplace injuries.

From a formal point of view, telescopic conveyors are recognized as effective solutions for enhancing logistics productivity, operational safety, and space optimization.

And let’s not forget the long-term cost savings. Fewer injuries mean fewer insurance claims. Faster operations mean quicker turnaround. That’s good news for your bottom line.

Whether you’re running a small warehouse or managing a large distribution center, investing in a telescopic belt conveyor can seriously streamline your operations. It's not just a piece of equipment—it’s a way to modernize your entire loading process.

So next time you’re stuck waiting on slow, manual unloading? Just imagine how a telescopic conveyor could slide right in and change everything.

Cooling Needs
You need to know how much heat your injection molding machine creates. The heat load tells you how much cooling power you need. When you melt plastic, the machine produces a lot of heat. You must remove this heat quickly to keep the process stable. If you choose a chiller that cannot handle the heat load, your parts may not form right. You can ask your machine supplier for the heat load value. You can also use online calculators to estimate it. Always add a safety margin to your calculation. This helps you avoid problems during peak production.

Machine Size & Cycle Time

The size of your machine and how fast it runs both affect your cooling needs. Large machines need more cooling. Machines with short cycle times also need more cooling because they work faster. If you run many cycles per hour, your chiller must keep up. You should check the tonnage of your machine and the average cycle time. Make a list of all machines if you use more than one. This helps you pick the right injection molding chillers for your setup.

Tip:Write down your machine size and cycle time before you start looking for a chiller. This makes the selection process easier.

Ambient Conditions
The temperature and humidity in your factory change how well your chiller works. Hot or humid air makes it harder for the chiller to cool your machine. If your factory gets very hot in summer, you may need a bigger chiller. You should also think about where you will place the chiller. Some chillers work better indoors, while others work better outside. Always check the chiller’s performance in your local climate.

Air-cooled vs.Water-cooled

There are two main types of injection molding chillers. One type is air-cooled. The other type is water-cooled. Air-cooled chillers use fans to move air over coils. This helps take away heat from the machine. You can put air-cooled chillers almost anywhere. They do not need extra water to work. These chillers are good if water is costly or hard to find. Water-cooled chillers use water to get rid of heat. You must have a steady water supply for them. Sometimes, you also need a cooling tower. Water-cooled chillers are usually quieter. They can last longer than air-cooled chillers. They work best in big factories with good water systems.

Tip:Pick air-cooled chillers if you want an easy setup. Choose water-cooled chillers for better efficiency and if you have water.

Central vs. Portable

You can choose central or portableinjection molding chillers. Central chillers cool many machines at the same time. You put them in one place and connect all your machines. This saves space and makes it easier to fix them. Portable chillers can move from one machine to another. Use them if you only need to cool one machine. They are good if you want to move them around.

Hydraulic vs. Electric Machines

The kind of machine you have is important. Hydraulic machines use oil to move their parts. They make more heat than electric machines. These machines need stronger chillers. Electric machines use motors and make less heat. You can use smaller chillers with electric machines. Always match the chiller to your machine type for the best results.

Note: Look at your machine’s manual to see which chiller is best.

Selection Criteria

You need a chiller that can cool your machine enough. Cooling capacity is how much heat the chiller can take away in a certain time. If the chiller is too small, your machine might get too hot. This can make your molded parts turn out wrong. Always check your injection molding machine’s heat load. Add a little extra to be safe during busy times. Most suppliers show cooling capacity in tons or kilowatts. Make sure the chiller meets or goes above what you need.

Tip:Write down your machine’s heat load and compare it to the chiller’s rated capacity before you buy.

Maintenance and Uptime

Taking care of your chiller is important for smooth work. Water-based systems often need less cleaning because they do not get dirty as fast. Easy maintenance means your machines can run longer without stopping. Good chillers have strong parts and smart controls. These help you stop breakdowns and keep your factory working. Your maintenance team should check, clean, and fix the chiller often. This keeps your injection molding chillers working well and cuts down on stops.

Maintenance teams must:

• Fix chillers fast when there is a problem.
• Do regular checks to stop problems before they start.
• Work with operators to solve issues quickly.
• Follow safety rules and keep good records.
• Learn about new systems and controls.

Sizing Steps

You need to size your chiller correctly to keep your machines running well. Start by finding the heat load for each machine. Write down the number you get from your machine manual or supplier. Add up the heat loads if you have more than one machine. Always include a safety margin of 10-20% to cover extra heat during busy times.

Follow these steps to size your chiller:

1. List all machines that need cooling.

2. Find the heat load for each machine.

3. Add the heat loads together.

4. Add a safety margin.

5. Choose a chiller with a cooling capacity that matches or exceeds your total.

Installation Needs

Proper installation keeps your chiller working well. Place the chiller on a flat, strong surface. Make sure there is enough space around it for air flow and maintenance. Connect all pipes and wires as the manual shows. Use clean water if you have a water-cooled chiller. Check for leaks after you finish.

You should also:

• Keep the chiller away from dust and heat sources.

• Make sure power supply matches the chiller’s needs.

• Train your team on how to use and check the chiller.

It is smart to look at different chillers before you buy. First, check the main features of each one. Look at cooling capacity, temperature control, and condenser type. Make a list of brands that match what you need. You can use a table to keep your notes organized:

Read reviews from other people who use these chillers. Ask if they are reliable and if spare parts are easy to find. This helps you avoid trouble later.

Budget & Quality

You need to think about both price and quality. Do not pick the cheapest chiller if it will not work well. Cheap chillers may break more or use more energy. Good chillers last longer and save money in the long run. Check the warranty and after-sales help. Good support can save you time and stress. Make sure you know the full cost, including setup and care.

Tip:Spending a bit more at first can save money on repairs and energy later.

It is a good idea to talk to experts before you buy. Find people who know about injection molding machines and extra equipment. They should know about chillers, thermolators, and resin dryers. Experts can help you pick the right chiller and plan for care. They can also help if something breaks. Experts often work with maintenance teams to keep things running. They know how to make cycle times better and cut down on waste. This help lets you get the most from your new chiller.

When you ask for expert help, look for:

• Real experience with the equipment
• Skill at fixing problems
• Ability to judge what to buy
• Teamwork with maintenance and production
• Ideas for making things work better

You can pick the right chiller by following some easy steps. First, make sure you size the chiller correctly. Keep the temperature steady for good results.

Air Cooled Screw Chiller Overview

How It Works

Air cooled screw chillers use a closed refrigeration cycle to take away heat from factory processes. There are four main steps in the system: compression, condensation, expansion, and evaporation. The screw compressor has two spiral rotors that spin together. This design helps the refrigerant get squeezed gently and quietly. Next, the refrigerant goes to the condenser. Fans blow air over copper tubes and aluminum fins. This step lets heat escape into the air. The refrigerant cools down and passes through an expansion valve. This valve lowers the pressure. In the evaporator, the refrigerant takes heat from the process water. This cools the water before the cycle starts again. The OUMAL 30 Ton Air Cooled Screw Chiller uses this process to give steady and dependable cooling for many factories.

• The system has these parts:

  • Compressor

  • Condenser

  • Evaporator

  • Control system

These parts work together to make a high-efficiency solution for cooling in factories.

Key Features

The OUMAL air cooled screw chiller has a semi-hermetic screw compressor, a copper condenser, and a shell-and-tube evaporator. It uses a Siemens PLC control system with a touch screen, so it is easy to use. The chiller uses R-407C, which is a refrigerant that is better for the environment. It meets strict rules for the environment. Special safety features help keep the cooling system working well.

Main Applications

Air-cooled chillers are used in many industries that need reliable chillers for cooling. Some common uses are:

• Plastics factories use them to control mold temperature

• Electronics factories use them to keep things stable

• Chemical plants use them to stay safe

• Food and drink factories use them to cool things fast

• Medical and drug companies use them for clean rooms

These chillers also work well where there is not much water. The OUMAL air cooled chiller can be used with other cooling systems. This makes it a good choice for many factory cooling needs.

System Sizing

Flexible Capacity

Factories need chillers that can handle many jobs. Sometimes, factories change their machines or add new ones. A modular design lets chillers fit different needs. The OUMAL air cooled screw chiller has a modular design. Users can pick the size and features they want. They do not have to buy a chiller that is too big or too small. This helps save both money and energy.

Capacity control is also very important. The OUMAL process chiller can change its cooling power in steps from 25% to 100%. This means it can match how much cooling is needed at any time. If the factory needs less cooling, the chiller uses less energy. If more cooling is needed, the chiller gives more power. This makes the system work well and stay reliable.

• Step modulation for capacity control helps:

  • Use less energy when cooling needs are low

  • Make the compressor last longer

  • Keep the temperature steady for sensitive jobs

Some chillers use variable-speed drives. These drives let the compressor and fans change speed smoothly. This gives even better control and saves more energy. Using the right controls can lower electricity use by over 12% in some cases. The OUMAL process chiller uses smart controls to work its best in all situations.

Sizing Tips

Getting the right size chiller is very important. If the chiller is too small, it cannot cool enough. If it is too big, it wastes energy and costs more to run. Here are the main steps to size an air cooled screw chiller:

1. Find out the total heat load. Add up heat from machines, people, and outside. Think about the temperature and humidity you want.

2. Look at the type of factory and how many hours it works each day. Check how much heat the equipment makes.

3. Use this formula: Capacity (Tons) = Total Heat Load (BTUs) / 12,000. This tells you the size you need.

4. Pick the right chiller type for your job. Screw chillers are best for big factories and tough jobs.

5. Plan for the future. Think about adding new machines or working longer hours. Do not just look at cost. Efficiency and how well it works over time are most important.

Tip: Always talk to a chiller expert before you decide. OUMAL can make custom chillers for special needs. Their team can help with sizing and design so the chiller fits your job.

Industrial chillers like the OUMAL model can be made to fit each project. This makes sure the system works well and saves energy. Good planning and the right features help factories get the best from their cooling system.

Energy Efficiency

Compressor Technology

Industrial chillers use special screw compressor technology to save energy. The screw compressor has two rotors that spin together. This design makes the compressor quiet and smooth. Many air-cooled chillers use this compressor because it saves power. It also works well in big factories. The compressor can change its speed and power. This helps match how much cooling the plant needs. So, the chiller does not waste energy when less cooling is needed.

• Screw compressors help chillers by:

  • Keeping the temperature steady and accurate

  • Using less electricity in big buildings and cooling jobs

  • Giving many cooling options for different needs

  • Letting users adjust settings to save more money

Some brands, like Daikin and Trane, use screw compressors with high energy ratings. These compressors help factories use less electricity. The OUMAL air cooled chiller uses a semi-hermetic screw compressor. This type is known for being efficient and working well for a long time.

Smart Controls

Smart controls are important for making chillers work better. Many new chillers use PLC systems and touch screens. These controls let workers set and watch the chiller in real time. The system can change how it works based on cooling needs. This saves energy and keeps the temperature even.

The OUMAL air cooled screw chiller uses a Siemens PLC control system. It has a touch screen that is easy to use. This system lets workers make changes fast and react to factory needs. Smart controls also help keep the system safe. They watch for problems like too much pressure or overload. Workers can see warnings and fix problems before they get worse.

Note: Smart controls and energy systems work together to save energy. They help the chiller run only when needed. This lowers costs and makes the chiller more efficient.

Reducing Costs

Industrial chillers help factories spend less money in many ways. Air-cooled chillers do not need cooling towers or extra water. This means they use less water and need less care. Using eco-friendly refrigerants, like R-407C, is good for the earth. It also helps the chiller work well in hot weather.

Studies show water-cooled chillers use less power than air-cooled chillers. But air-cooled chillers save money because they do not need water treatment or towers. This makes them good for places with little water. The OUMAL air cooled screw chiller uses R-407C. This helps it work well and saves money on water.

Factories that buy variable speed drive air-cooled screw chillers often get their money back in about 22 months. This means energy and care savings pay for the chiller in less than two years. Many factories pick air-cooled chillers to help the planet. These chillers use less material and lower-GWP refrigerants. This helps cut down on carbon emissions.

Tip: Picking the right chiller with smart controls and good compressors helps factories save money, use less energy, and protect the environment.

Maintenance and Reliability

Easy Maintenance

Air cooled screw chillers last a long time in factories. They have fewer moving parts than other chillers. This means they do not break as often. The design lets workers reach important parts easily. Technicians can check and fix things fast. Many factories pick screw chillers for strong cooling and easy care. Screw chillers need fewer repairs than reciprocating chillers. They also cost less to keep working over time. Cleaning the condenser coils and checking oil levels is important. This helps the chiller work well.

Troubleshooting Water Cooled Screw Chillers: Common Faults and Fixes

You might have high-pressure trips, refrigerant leaks, or compressor overload when using a water cooled screw chiller. Fast troubleshooting helps lower downtime and expensive repairs. Regular checks and preventive maintenance help find problems early. Knowing your water cooled chiller well helps you see issues before they get worse.

Water Cooled Screw Chiller Faults

• High Pressure

High pressure alarms can happen in your water cooled screw chiller. Air or other gases in the system can cause this. Too much refrigerant or a dirty condenser can also be the reason. If the cooling water is too warm, pressure goes up fast. Low water flow makes pressure rise too. Dirt in pipes or a broken water pump can cause high pressure faults. To fix these, clean the condenser and check water flow. Adjust the refrigerant level if needed.

Tip:If you see high pressure, always look for dirt on the condenser surface.

• Low Pressure

Low pressure is another problem you might see. This can happen if there is not enough refrigerant or if there is a leak. Cold weather can make water and oil colder, causing low pressure alarms. Blocked filters or pipes can also lead to this. A bad expansion valve or electrical relay can be the cause too. Check for leaks and clean the filters. Make sure all valves are working right.

• Water Flow Loss

Water flow loss is a common fault in water cooled chillers. This happens if the water pump stops or pipes get blocked. Air in the system can also cause it. Low water flow can make the chiller shut down or work poorly. Always check pumps and pipes for blockages or leaks.

• Refrigerant Leaks

Refrigerant leaks are serious in water cooled screw chillers. Leaks make cooling worse and use more energy. Some refrigerants can hurt the environment if they escape. Check for leaks often and fix them fast. This helps avoid high costs and protects the environment.

• Oil System Issues

Oil system issues can harm your chiller. Oil leaks, dirty oil, low oil pressure, or hot oil are common faults. These problems lower lubrication and can make the compressor overheat or wear out. Check oil levels often and change oil when needed. Clean or replace oil filters as well.

• Electrical Problems

Electrical problems often cause chiller faults. Loose wires, bad relays, or blown fuses can stop the chiller. If your chiller will not start, check the electrical panel first. Make sure all wires are tight and replace any broken parts.

• Noise and Vibration

Strange noises or vibration can mean mechanical problems. Loose screws, unbalanced fans, or pipes not fixed well can cause rattling or banging. If you hear loud or repeating noises, look for loose parts or debris. Finding these problems early helps stop bigger faults and keeps your chiller working well.

Chiller Troubleshooting Steps

Troubleshoot Pressure Issues

Pressure problems in your chiller can cause shutdowns or poor cooling. You can follow these steps to find and fix pressure faults:

1. Check all valves. Make sure refrigerant valves are open. Isolation valves should stay closed unless you need them for repairs.

How Process Chillers Work

Process chillers use a simple cycle to cool things down. First, the refrigerant goes into the evaporator. It takes heat from the process fluid, like the liquid used in metal finishing. The refrigerant turns into a gas. The compressor pushes this gas to a higher pressure and temperature. Then, the gas goes to the condenser. In air-cooled chillers, the condenser lets out the heat into the air, and the gas turns back into a liquid. The liquid goes through an expansion valve, which makes it cooler and lowers the pressure. The cycle starts again.

1. The refrigerant takes heat from the process fluid in the evaporator.

2. The compressor makes the refrigerant gas hotter and under more pressure.

3. The condenser lets out heat to the air, turning the gas into a liquid.

4. The expansion valve cools the liquid, and the cycle repeats.

Microcomputer controls help keep the temperature steady. They let the chiller keep the water temperature close to the same, usually within ±1°C. This is important for process chillers in metal finishing. The OMC-10A chiller uses these controls to keep things safe and make sure the results are good.

Metal Finishing Cooling Needs

Temperature Control Challenges

Keeping things cool is very important in metal finishing. Jobs like anodizing, plating, and quenching need steady temperatures. If the temperature changes a lot, metal can bend or break. It might also get weaker. Workers have some problems when they try to keep the right temperature:

• Some materials, like plastics or MDF panels, can bubble or crack if they get too hot.

• Certain parts must stay within a set temperature. If it gets too hot, these parts can bend or break.

• Some parts, like refrigerant compressors, need careful heating and cooling.

• Metal parts with different thicknesses can heat up unevenly. This makes it hard to keep the whole part at the right temperature.

• Big, heavy parts need more heat to process. This can slow down work and cost more money.

A chiller helps by keeping the temperature steady. The 10 HP chiller uses sensors to check for temperature changes during busy times. If the temperature goes up, the chiller sends coolant through heat exchangers to cool things down. When the temperature is right, the system stops sending coolant. This automatic control keeps everything safe and working well.

Application Examples

Keeping the temperature steady helps protect products and machines. Here are some ways bad temperature control can hurt metal finishing:

1. If the temperature changes, metal can get bigger or smaller. This can cause size mistakes.

2. High heat can change the metal’s surface or inside. The metal can get softer or weaker.

3. Too much heat can burn or discolor the metal. It can also cause other surface problems.

4. Hot conditions can wear out tools faster. Grinding wheels can get damaged too.

5. Bad temperature control can leave stress in the metal. This can make it bend or break later.

A 10 HP chiller gives the cooling needed to stop these problems. By keeping the temperature in a small range, the chiller helps each job go well. This means better products, less stopping, and longer machine life. Good chillers also help make more products. They help every finished product meet high standards.

Benefits of 10 HP Chillers

Efficiency and Reliability

10 HP chillers save energy and work well in metal finishing. They have special compressors that change speed when needed. This helps keep the temperature steady and uses less energy. Many factories say their energy use drops a lot after using these chillers. The system now uses only about one-third of the energy older chillers used. The pumps also use less power, so more energy is saved.

Factories have fewer problems because the chiller keeps water temperature and pressure steady. This helps protect machines and makes products better.

Chillers with variable-speed compressors do not turn on and off too quickly. This means less stress on the compressor and it lasts longer. Electronic safety features help stop problems before they happen. Soft-start controls help the system start gently and protect the parts. These things make the chiller good for busy factories.

These chillers are small and fit well in crowded places. Wheels make it easy to move them around. The system uses closed water loops, so the water stays clean and needs less care.

Key reliability features include:

• Steady temperature for better results

• Fewer breakdowns because of safety features

• Less waiting because setup is fast and easy

• Energy-saving choices that cost less to run

Low Maintenance

10 HP chillers need less care than old ones. Most need a check-up once a year. This means checking oil, cleaning coils, and looking at wires. Trained workers should look for leaks and test safety parts. You do not need to change the oil often, but checking it helps keep the compressor healthy.

Typical maintenance steps:

1. Do all weekly and monthly checks during the yearly service.

2. Check the oil for water and acid.

3. Look at and tighten all wires.

4. Clean and paint any rusty spots.

5. Clean air filters and coils.

New chillers use safe refrigerants that last longer. Better motors and coils help stop breakdowns. Chillers that are the right size do not have as many problems. This means less fixing and less time when the chiller is not working.

Many factories say they spend 80% less time on maintenance with new chillers. They also need outside help much less. Having spare parts and regular checks helps stop long waits for repairs.

Safety features keep the chiller and factory safe. Some of these are:

• Protection from too much electric current

• Switches for high and low pressure

• Timers for safety delays

• Power phase protection

• Anti-freeze protection

These features help the chiller work well and stop big problems. This means the system is efficient, works well, and lasts a long time for metal finishing.

Industrial Process Chiller Comparison

10 HP vs. Other Capacities

Picking the right process chiller depends on what the factory needs. A 10 HP chiller gives good cooling and saves energy. Smaller chillers, like 3 HP or 5 HP, are for easy jobs or small tanks. They use less power but can’t cool big jobs. Bigger chillers, like 20 HP or 30 HP, cool more and fit large factories. These are best when many machines run at once.

A 10 HP chiller is good for medium or big metal finishing work. It cools enough for jobs like anodizing, plating, and quenching. This size works well without wasting energy. Many companies pick 10 HP chillers because they are flexible. They can cool more than one machine or tank at the same time. This makes them a smart pick for businesses that want to grow.

Tip: You can change some parts to fit your job. Pick different refrigerants, evaporators, or power supplies. Stainless steel tanks and pumps stop rust and last longer. Touch screens and safety features make it easy and safe to use.

Air to Water vs. Other Types

Factories can choose air-to-water, air-to-air, or water-to-water chillers. Each type works best for certain jobs. The table below shows how air-cooled and water-cooled chillers are different:

Air-to-water chillers use air around them to cool down. They are simple to set up and move. These chillers work best in places that are not too hot. Water-cooled chillers use water from a cooling tower. They cool better and save more energy, even when it is hot outside. Their cooling stays the same even if the weather gets warmer.

Factories can add special features to chillers for their needs. Some options are titanium tube evaporators, very low temperature settings, and smart controls. These help the chiller work for any metal finishing job and keep the system running well.

10 HP process chillers are special in metal finishing for many reasons.

• They use scroll compressors and eco-friendly refrigerants to save energy. These parts also help the environment.

How They Work

Water Cooled Screw Chiller

A water cooled screw chiller gives strong cooling for big places. It takes heat from your building and puts it into water. The water goes through pipes to a cooling tower. The cooling tower lets the heat out into the air. You find these chillers in hospitals, factories, and big offices. They are good for places that need a lot of cooling. Groups like ASHRAE 90.1 and ARI say these chillers work well for big jobs and save energy. New models use special drives and better refrigerants. This helps save more energy and follow strict rules.

Air Cooled Chiller

An air cooled chiller is good if you want something simple. It uses fans to blow air over coils to cool the refrigerant. The heat goes straight into the outside air. You do not need a cooling tower or extra water. These chillers are good for small buildings or places with little water. They are easier to put in and take care of. But they might use more energy, especially when it is hot outside.

Main Differences

The biggest difference is how each system gets rid of heat. Water cooled screw chillers use water and cooling towers. Air cooled chillers use air and fans.

Here is a quick look at how they work:

A water cooled screw chiller gives better efficiency and heat transfer. Air cooled chillers are easier to set up and cost less at first. But they may not work as well in big or busy places.

Comparison Factors

Energy Efficiency

You want to use less energy and save money. Water cooled screw chillers are usually more efficient. They use water to move heat, which works better than air. Studies show that if you run chillers together in a smart way, you can cool up to 93 kW more each hour. This saves a lot of energy over time. In big buildings, smart controls help cut energy use by over 11%. They also make the Coefficient of Performance (COP) go up by more than 21%. This means your system does more work for each unit of electricity. Air cooled chillers can save energy too if they have variable-speed fans and smart controls. But they are not as efficient as water cooled chillers, especially when it is hot outside.

Costs

You need to think about both the starting cost and the cost to keep it running. Water cooled screw chillers cost more to put in. You need a cooling tower, pumps, and extra pipes. The base cost is about $1,000 for each ton of cooling. Air cooled chillers cost less to install because they do not need extra water systems. But they may use more electricity, especially in hot or dry places. Here is a quick look at cost factors:

Maintenance

You want a system that is easy to take care of. Water cooled screw chillers need more work. You have to check the cooling tower and clean the pipes. You also need to watch for scale or rust. These systems have more moving parts. Air cooled chillers are simpler. You just clean the coils and check the fans. This means less downtime and fewer repairs. If you want less work, air cooled chillers are easier to handle.

Capacity

If your building needs a lot of cooling, water cooled screw chillers are better. They can handle big loads and work well in hospitals, factories, or tall office buildings. They can run for long hours without losing power. Air cooled chillers are good for smaller buildings or places that do not need as much cooling. They may not work as well if you try to cool a big space or run them all day.

Climate Suitability

The weather where you live matters. Water cooled screw chillers work well in any climate, even if it is hot or humid. They do not lose much efficiency when it gets hot outside. Air cooled chillers work best in places that are not too hot. When it is hot, they use more electricity and do not cool as well. Studies show that in Mediterranean climates, smart fan controls can save up to 12% on electricity. In subtropical areas, advanced controls help air cooled chillers save energy. But water cooled chillers still work better in high heat.

Space and Noise

You need to plan where to put your chiller. Water cooled screw chillers need a mechanical room and space for a cooling tower. They run quietly, which is good for hospitals or offices where noise matters. Air cooled chillers go outside. They need open space and make more noise because of their fans and compressors. If you do not have much indoor space or do not mind noise, air cooled chillers may work for you.

Lifespan

You want your chiller to last a long time. Water cooled screw chillers usually last longer—often 20 to 30 years—if you take care of them. Their parts wear out slowly because they run in steady conditions. Air cooled chillers last about 15 to 20 years. Weather and temperature changes can make them wear out faster.

If you want a quiet, long-lasting, and efficient system for a big building, water cooled screw chillers are often best. For smaller spaces or places with little water, air cooled chillers are simpler and cost less.

Tip: Chillers work best at 40-60% of their top power. If your chiller is too big or too small, you waste energy and money.

Climate and Water

Where you live and how much water you have matter a lot. Hot weather makes chillers work harder. Humid air means you need more cooling. If you live where it is hot or humid, a water cooled screw chiller keeps working well. In dry places or where water is hard to get, air cooled chillers or adiabatic cooling systems use up to 90% less water than old cooling towers.

• Ambient temperature: Hotter weather uses more energy.

• Relative humidity: More humidity means you need more cooling.

• Water availability: If water is low, air cooled chillers are better.

Smart technology, like IoT monitoring, helps you watch water, temperature, and energy use. This makes it easier to change your system for the best results.

Budget

You need to think about your money and your cooling needs. The cost to buy, run, and fix your chiller all matter. Here is a quick look at new market numbers:

Newer chillers with AI controls can use up to 30% less energy. Cloud monitoring helps you save money by making your chiller work better and break down less. If you do not have much money, an air cooled chiller costs less to buy and fix. If you want to save money in the long run, a water cooled screw chiller with smart controls can lower your bills over time.
