Water Cooled Chiller: The Complete Buying Guide

Chapter 1: What is a Water-Cooled Chiller?

Water Cooled Chiller is a device used to remove heat and transfer it to the environment.

Water-cooled chillers are mostly used in air-conditioning, industry, or any other specific places that require temperature control.

Water Cooled Chiller has advantages over air-cooled chiller in terms of capacity, efficiency, life, and environmental impact. In the cycle of cooling, Water Cooled Chiller uses water instead of air for refrigerating.

Water Cooled Chiller is a machine or machine unit that absorbs heat from process water and transfers it to a water tower or any other water source that serves the same function.

The main components of the water-cooled chiller are evaporator, condenser, compressor and expansion valve.

In the cycle of refrigerating, the compressor draws the vapor from the evaporator and compresses it into high-pressure air and transfers it to the condenser.

Inside the condenser, the heat of the high-pressure air is removed to the ambient air or condenser water and the high-pressure air is transformed into a high-pressure liquid.

The liquid then goes through the expansion valve and enters the evaporator as vapor, where the chilling process is taking place in this link. And the vapor then again is drawn to the compressor repeats the cycle.

Water-Cooled Chiller

 Water Cooled Chiller

Water cooled chiller is one kind of industrial chillers, so that water cooled chillers can be used in various applications, like injection molding, extruding, thermal forming, foaming, food and beverage processing, die-cutting, tooling, etc.

When we coming into the topic of water-cooled chiller, we can’t avoid the water-cooled chiller partner–water cooling tower.

A water-cooled chiller must work together with the proper cooling tower and circulation water pumps.

Water Cooling Tower Working Principle

Chapter 2: How does a Water-Cooled Chiller work?

As suggested by its name, Water Cooled Chillers use circulating water to take away the heat produced by industrial equipment or process, in contrast to air-cooled chillers that disperse heat by air.

Please take a look at below video for how water-cooled chiller works to get more details:

How a Water Cooled Chiller Works?

As we know from above, the work cycle of Water Cooled Chiller is like this: the refrigerant vapor after chilling the process water in the evaporator is drawn into the compressor, where both of its pressure and temperature are elevated.

The refrigerant in the form of a high-pressure high-temperature form then is discharged into the condenser. There its heat is removed by the cooling water, which runs through another cycle connected to the outdoors water tower.

The refrigerant then is condensed into liquid and falls at the bottom of the condenser.

Through orifice (expansion valve, caterpillar tubing), the low-pressure refrigerant enters the evaporator in the form of vapor to perform its work-chilling the process water and then repeats the cycle.

Water Cooled Chiller Working Principle


 Water Cooled Chiller Working Principle

So here we can break down the water-cooled chiller into the following main parts: Compressor, Condenser, Expansion Valve, Evaporator, and also in the cooling tower cycle, the cooling tower and its auxiliary devices.


Various types of compressors are used in Water Cooled Chillers for different cases due to preferences. centrifugal, screw, scroll or reciprocating types are most commonly used.

Each one has its pros and cons over others.

The compressor provides the refrigeration power of the chiller. By creating a pressure difference, it moves the refrigerant around the system.

The compressor is usually installed between the evaporator and the condenser. It is connected to the internal or external motor as a driving force.
Water Chiller compressor

Danfoss and Copeland Scroll Compressor


For water-cooled chiller, it using water-cooled shell and tube type condenser.

The shell and tube condenser links between the compressor and the expansion valve.

Its function is to remove the heat the refrigerant takes from the process water in the evaporator.

Water Cooled Shell and Tube Condenser

After the compressor compresses the refrigerant and sends it to the condenser, the condenser use air or water to condense the refrigerator.

In the case of Water Cooled Chillers, the condenser connects with the water tower outdoors and transfers the heat to from the refrigerant to the water tower.

In the condense water cycle, water runs inside the pipe repetitively between the condenser and the water tower. The water and the refrigerant are separated by the pipe wall.

The water runs inside the pipe while the refrigerant on the pipes. After the refrigerant is chilled, it falls into the trough of the condenser and is collected.

water cooled condenser

Water Cooled Shell and Tube Condenser

Thermal Expansion Valve:

The expansion valve is a very important refrigeration spare parts for a water-cooled chiller.

It locates between the condenser and evaporator. It functions as a device to reduce the pressure and increase the volume of the refrigerant, which is condensed into liquid in the previous link-condenser.

How Thermal Expansion Valve Works

Through the expansion valve, the refrigerant can enter the evaporator as vapor and pick up heat from the process water.

Different types of expansion valves are available, such as thermal expansion valve, electronic valve, pilot operated expansion valve and orifice expansion valve, caterpillar tubing, etc.thermal expansion valve models

The most popular Thermal expansion valve brands are Danfoss and Emerson.

Danfoss expansion valve

Danfoss Expansion Valve


The evaporator is the link where the heat of the process water is extracted by the refrigerant and the chilled process water is pumped to where it is needed.

The process water comes in and out of the evaporator in a cycle for chilling. In the evaporator, the refrigerant runs in the pipe while the water in the shell.

There are 3 types of evaporators for the water-cooled chiller, Stainless steel water tank with a coil, close-loop shell, and tube heat exchanger and stainless steel plate heat exchanger.

This depends on the client requirements and project site condition to select which type condenser is suitable for your water-cooled chiller.

Now let’s take a look at how stainless steel plate heat exchanger working? then you will have a general idea about this type of water cooled chiller evaporator.

Stainless Steel Plate Heat Exchanger Working Principle

In terms of system, water-cooled chiller having the refrigerant circulating system, water circulating system, and electric automatic control system.

The refrigerant circulating system is the cycle we explained above.

The water cycle pumps chilled process the water from the water tank to the equipment that requires chilling and absorbs the heat and then returns to the water tank.

The electric automatic control system includes a power unit and automatic control devices. switches, starter, circuit breakers, speed controller and power monitoring devices control the flow of electrical power of the chiller.

The automatic control system includes temperature controller, pressure control, delayers, relay, overload protector, etc. to monitor various aspects of the chiller’s performance and to make adjustments accordingly.

Chapter 3: What is the difference between a Water-Cooled Chiller and an Air-Cooled Chiller?

For industrial applications, people weigh the pros and cons of the two options, Water Cooled Chillers or Air Cooled Chillers.

Before we starting this topic, please take a look at this video to get a rough idea of the difference between the air-cooled chiller and water-cooled chiller:

Difference Between Air Cooled Chiller And Water Cooled Chiller

Both air chillers and water chillers have their advantages and disadvantages.

Now we shall discuss from a few aspects the difference between the two chiller types and come to a conclusion which type is preferred under the circumstances.

Air Cooled Chiller and Water Cooled Chiller

3.1 Cost

Both air cooled chiller and water cooled condensing the refrigerant in the condenser.

The air-cooled condenser uses propeller fans to draw ambient air over a finned coil to condense the refrigerant, while water-cooled condenser uses re-circulating water from a water tower to condense the refrigerant.

water cooled chiller VS air cooled chiller

Water Cooled Chiller VS Air Cooled Chiller

3.1.1 Installation Cost and Maintenance Cost:

As we know the water-cooled chiller requires a cooling tower (water tower) which usually is installed outdoors, thus it has higher installation and maintenance costs than the air-cooled chiller.

Besides the water tower, a water pump and chemical treatment for the water circulating loop add to the initial investment cost and the regular maintenance cost.

In this case, a water-cooled chiller is costly than an air-cooled chiller.

Water Cooled Chiller Installation

As we know, the major difference between the air-cooled chiller and water-cooled chiller is the condenser types or condensing ways. For water-cooled chiller must connect with an external water cooling tower, but for air-cooled chiller, it’s not necessary.

How Water Cooled Chiller and a Cooling Tower Work Together?

3.1.2 Operation Cost:

In the case of Air Cooled Chillers, the condensing temperature depends on the ambient dry-bulb temperature, but for Water Cooled Chillers, the refrigerant condensing temperature depends on the condensing water temperature and flow rate, which equals to the wet-bulb temperature.

As usual, the web-bulb temperature is lower than dry-bulb temperature, it is not difficult to see that refrigerant condensing temperature in a water-cooled chiller is considerably lower than the air cooling chiller, so the water cooling system is more efficient than the air-cooled chiller and thus more saving in terms of electricity consumption.

So water cooled chiller is more suitable for the area which has plenty of water sources.

3.1.3. Cooling efficiency

Like a coin has its two sides, Considering the cost, we must pay attention to the cooling efficiency.

As we all know air-cooled chiller drops the boring heat by exhaust cooling fans. But water-cooled chiller exchanging heat by using a water cooling tower or water source.

The two different cooling methods will give quite a different cooling efficiency. It is obvious that water-cooled chiller is more effective in cooling performance than an air-cooled chiller.

As testing data from TopChiller engineering, the same chiller models, the water-cooled chiller is more 20% cooling efficiency than an air-cooled chiller.

Water Cooled Chiller Advantages

The advantage of Air-Cooled Chiller and Water-Cooled Chiller

Of course, you should consider your specific circumstances.

For example, if you are in the area where water cost is extremely high or the water quality is very poor and requires a high cost in water treatment, then air-cooled chiller might be more economical overall speaking.

If you have questions in selecting a water-cooled chiller or an air-cooled chiller for your application, just feel free to contact our technicians or salespersons.

We shall be glad to look into your situation and offering our professional advice.

Please, you can also send us your Water Cooled Chiller inquiry.

3.2 Cooling Capacity

As regards as chiller cooling capacity, Air Cooled Chillers are usually available in sizes up to about 500tons.

But in contrast, Water Cooled Chiller capacity is available up to 1000tons, and tailor-made designs can be up to even higher.

So if you have a higher capacity requirement, Water Cooled Chiller might be preferred.

3.3 Service Life

In terms of service life, Water Cooled Chiller is more lasting than Air Cooled Chiller.

This is mainly because Water Cooled Chillers are installed indoors (except for the cooling tower/water tower), while most of the Air Cooled Chiller stays outdoors.

The other reason is large scale Water Cooled Chillers are built with heavy-duty and industrial-grade components.

service life

3.4 Installation Space and Environment Requirements

Solely from the size of the chiller machine, an Air-Cooled Chiller is bigger than a Water Cooled Chiller. But a Water-Cooled Chiller requires connecting to the water tower.

We must consider the chiller installation space problem.

So in case a water tower installation is not a problem or there is a water tower in place, a Water Cooled Chiller might be preferred.

However, in case the indoor space is very limited and ventilation, temperature, environmental humidity conditions are favorable, Air Cooled Chillers might be preferred.installation space and environment

From the above comparison, the users should look into their specific circumstances and needs to evaluate both options. The simple and arbitrary conclusion should not be made on which type is more favorable.

Chapter 4: Water Cooled Chiller Applications

Water Cooled Chiller Applications

Water Cooled Chiller can be used in air-conditioning or industry. Here we focus on the application in the sector of the industry.

In various manufacturing processes, it requires chilled water/process water or liquid to cool down the products or equipment, for the purpose of protecting equipment, improving product quality, etc.

Water-cooled chillers are most commonly used in plastic industries, like injection molding, thermal forming, blow molding, extruding.

Water-cooled chillers are also used in die-casting, machine tooling, metalworking cutting oil and welding equipment, in pharmaceutical production, chemical processing, food, and drink processing, storing and transporting, they are widely used. And in agriculture, medical facilities, constructions, chillers have wide applications.


Water Cooled Chiller with its large capacity, can be centralized in the application.

In that case, a chiller can serve more than one cooling need, such as chilling process water for more than one injection molding machine.

Or when a chilling need is high, chillers can be decentralized too, in which case one application or one machine uses one water-cooled chiller.

In designing the manufacturing processes, both applications can be considered. You can combine both centralized and decentralized water-cooled chillers in the solution, as some applications have the same cooling requirements and some applications are not.

Below we choose applications in some important sectors and discuss them in detail.

4.1 Plastic Industry

Water cooled chiller is widely used in the plastic industry.

Appropriate cooling is essential in plastic product manufacturing. It could affect the product surface smoothness, brightness, and product forming.

Effective cooling can reduce scrap rate and hence reduce cost, improving efficiency, so the water-cooled chiller will do its job.

Water Cooled Chiller for Plastic Machine

4.1.1 Injection molding

Water-cooled chillers can remove heat not only from plastic molds but also from mold temperature controllers, hydraulic heat exchangers, feed throats of injection molding machines.

Water Cooled Chiller for Injection Molding Machine

Time-saving: In a cycle of one injection molding shot, cooling cover about an average of 95% of the cycle time.

Both heating and cooling are important in the process, but cooling can be regarded as critical. Even, identical-rate cooling results in high-quality products and efficient production.

With the right water-cooled chiller to cool quickly, you will save time and thus save a lot of costs, especially in high volume production.

Defect reducing: The reliable water-cooled chiller also ensures the coolant access to every location evenly and reduces the thermal stress defects, like warping, sink marks, weld lines, etc., which could cause you tremendous loss of profit.

Quality improving: In the first stage of shooting, thermoplastic resin pellets are heated to the degree that they are molted and then they are shot into the mold.

However, the thermoplastic resin can’t be molten for a too long time, otherwise, the chemical make-up might degrade and the plastic quality might be compromised. An accurate cooling solution is vital in this regard.

Product accuracy improving: For some high-precision products, dimensions tolerance is very strict. The cooling rate plays a significant effect on part dimensions. To make sure you reach the dimension target, you have to control the cooling cycles identical.

Plastic Machine Processing

4.1.2 Blow Molding

Water cooled chiller can also be found in blow molding machines.

Blow molding is a plastic manufacturing process by which hollow plastic parts are formed.

In the blow molding process, a plastic resin is melted down and formed into a parison or perform.

A parison is a plastic tube-shaped piece with a hole in one end, through which air can be compressed it.

water chiller for blowing molding machine

Water Cooled Chiller for Blow Molding Machine

Dehumidifying air: In the blow molding process, clean and dry compressed air is needed. The water-cooled chiller can be used to dehumidify the air effectively.

Cooling mold: In the blow molding process, if the cooling and forming are not effective, the product will not be in the right shape; the wall thickness will not be even; the color and brightness will not be sufficient. In the worst case, the products can’t even be formed.

Blow Molding cooling

Water Cooled Chiller for Cooling Mold

4.1.3 Extruding, Stamping, etc.

Extruding, plastic extruder extrusion line also needs to use a water-cooled chiller

Plastic extruders, extruding or stamping machines also need a steady cooling water source.

common setup for extrusion line

The extruded profile has to be cooled to the temperature that it can maintain the desired shape and dimensions.

Water Cooled Chiller is essential in removing heat effectively. Barrel cooling is also important in the extrusion process.

During the extrusion process, maintaining temperature control over the melt is very important. Chilling the barrel is one of the methods to control any over-heating of the plastic.

There are various kinds of manufacturing processes that require cooling that Water Cooled Chiller can perform the duties.

Please contact our technical team or salesperson if you have any needs or questions in your production processes.

The most important one we need to pay attention to is there is an external water tank together with an extruder machine, so if we give a water chiller solution or design, We must go for a closed-loop system water chiller without built-in water tank. This is an important factor.

Water Cooled Chiller for Plastic Extruder

4.2Food and Beverage Industry

Water cooled chiller is always used in the cooling food and beverage process.

In processing food and beverage, like mixing, cooking, or pasteurizing the products, water-cooled chillers are widely used to removes the heat during their production process.

Beverage, dairy, and drinking need a steady certain temperature controlled when their fermentation process. So the water-cooled chiller is a must machine.

Water Cooled Chiller for Fermentation

4.3 Medical Equipment and Medicines

Water-cooled chiller often used for cooling medical equipment like MRI machines and CT scanning machines.

MRI (Magnetic Resonance Imaging) is a medical examining method of creating images of human organization.

Water chillers have to be used to transfer heat from the MRI scanner to the air (in case of the air-cooled chiller) or cooling tower (in case of Water Cooled Chiller).

Low temperature storing of plasma, vaccines and other medicines that require low-temperature environment also uses chillers.

water chiller cooling process

Water Cooled Chiller For Medical Process

4.4 Anodizing

In anodizing processes, especially hard coating processes, a lot of heat is generated and cooling is a critical requirement.

Water-cooled chiller is a necessary partner machine for the anodizing industry.

4.5 Other industries

There are too many circumstances in the industry that chilling is a must and is critical in equipment protection and product quality guarantee.

If you have any special cases that need to have a cold water solution, please come to us and TopChiller will provide you professional advice and custom-made solution to your application.

Whatever there is boring heat need transfer, there must need a water-cooled chiller.

Chapter 5: Maintenance of Water Cooled Chillers

Buying a good quality water-cooled chiller is the first important thing but how to maintain the water-cooled chiller is the coming key point.

As we know Water Cooled Chillers have wide applications in various industries, Water Cooled Chillers are performing heavy duties in the production of the factories.

It is maintained and safe operation is essential to the industrial processors.

Keep a daily log, a checklist, and closely monitoring the chillers will help to keep the water-cooled chillers in peak performance and save cost and energy in production.

 water chiller maintenance

Maintenance of Water Cooled Chillers

Below are the tips for water-cooled chiller maintenance.

5.1 Keeping daily logs or checklist

Keeping daily logs or checklist can help you build a history of the machine’s operation conditions, like temperatures, pressures, fluid levels, flow rates, etc.

With records of a certain period, you could quickly detect abnormal operations and predict errors before causing bigger problems.

And the data will allow you to see the trend of change and identify the maintenance needs before they become an issue and thus cause a big loss.

Maintenance of Water Cooled Chillers

5.2 Keeping tubes clean to ensure efficient heat transfer

As heat transfer efficiency greatly affects the chiller performance, maintaining clean tubes is extremely important.

Contamination such as minerals, scale, mud, algae, and other impure substance will add to the thermal resistance and reduce the overall performance of the water-cooled chiller.

A good indicator of heat transfer efficiency is the condenser approach temperature. Higher approach temperatures indicate decreasing heat transfer is happening.

Water-cooled chiller’s condenser tubes should be cleaned regularly, preferably once a year.

You should also look into the specific situation of your case to decide the cleaning schedule.

water chiller maintenance

Maintenance of Water Cooled Chillers

5.3 Treating condenser water so as to prevent scale and corrosion

As the condenser water cycle circulates through open water sources-the water from a cooling tower, water treatment is required so as to prevent scale, corrosion, or biological growth.

These factors will lead to fouling in the condenser and impede heat transfer, decrease tube and piping effectiveness.

Annual inspection on the chilled water cycle is necessary. Water cooling tower maintenance will be discussed alone below.

water chiller maintenance

Maintenance of Water Cooled Chillers

5.4 Entering water temperature control

Try to maintain the entering water temperature low can save a lot of work for the water-cooled chiller and increase the efficiency of its performance.

Look into the specific environment and conditions of your case and try to improve this condition.

5.5 Maintaining sufficient refrigerant

The cooling amount depends on the number of refrigerant moves through the compressor. Thus it is important to maintain an adequate level of refrigerant so as to have desired machine performance.

In the case of refrigerant leaking, air or moisture entering into the system, performance efficiency will decrease and the liability of the system will be compromised.

Refrigerant charge lower than the required level will force the compressor to work harder but result in an unsatisfactory cooling effect.

water chiller maintenance

Maintenance of Water Cooled Chillers

5.6 Preventing non-condensable matters

Non-condensable matters such as air or moisture get into the cycle can cause lower pressure in the chiller, as the evaporator works in a vacuum environment.

Air or moisture reduces the performance efficiency of the water-cooled chiller up to 4% at 60% load and 7% at 100% load. The air purge unit is employed to minimize the non-condensable matters in the cycle.

5.7 Compressor oil checking

Compressor oil, a lubricant used to prevent wear and minimize corrosion, is better to be checked by the laboratory once a year. The oil should be changed if the analysis shows that it is necessary.

5.8 Maintaining the chilled water flow rate in the proper range

The too low or too high water flow rate will affect the chiller’s performance.

If the flow rate is too low, the water-cooled chiller efficiency will be lowered and lead to laminar flow in the end.

However, a flow rate too high will lead to vibration, noise and tube erosion.

The typical flow rate is in the range of 3ft-12ft (FPS).

5.9 Regular checking of starters and motors operation

To ensure the starter and motors operate efficiently, check the safety and sensor calibrations on microprocessor controls.

Electrical connections, wiring, switchgear also have been checked and hot spots or worn contacts have to be identified.

Detect any insulation faults by testing electrical motor windings for insulation resistance to the ground.
