Leading Water Chiller Manufacturers

A water chiller is a refrigeration system that uses water as a refrigerant for the removal of heat to control for cooling a process or equipment. In the completion of products or production operations, it is necessary to remove heat to maintain the quality of a product or avoid damage to equipment. Water chillers efficiently remove heat from equipment and use a heat exchanger to transfer the heat into the air. Read More…

Water Chillers Water chillers are cooling systems designed to facilitate heat exchange from water to a refrigerant and from the refrigerant into the atmosphere. Like most other liquid chillers, water chillers cool through a cycle of pressurization, condensation, depressurization, and evaporation of a refrigerant. Water chillers differ from other chillers in that they are used primarily to cool water for industrial applications.

A key factor for a water chiller is the pumping system that circulates the cooled water or a glycol and water solution. Circulating water removes heat and carries it back to the chiller for treatment. During the process, heat is transferred from the heated water to the chiller in a continuous cycle.

The cooling process provided by a water chiller is an important part of injection molding, tool and die cutting, food and beverage processing, chemical industry processes, lasers, and machine tooling. Heat is a common byproduct of industrial processes that needs to be removed for the protection of a process or to maintain efficiency. Water chillers provide consistent temperature and pressure to ensure the safety and effectiveness of equipment and avoid equipment failure.

How a Water Chiller Works

The four main components of a water chiller are the evaporator, expansion valve, condenser, and compressor. During the chilling process, water constantly cycles through these four elements where it absorbs heat and releases it. A key to the process is refrigerant, which changes from a liquid to a gas as it passes through the four parts of the water chiller unit.


The function of the compressor is to create a pressure difference that moves the refrigerant through the system. Compressors come in various shapes and sizes and include centrifugal, screw, scroll, and reciprocating. Regardless of the variations of compressors, all types are designed to perform the same function.

The compressor is located between the condenser and evaporator and is attached to an electric motor that provides power. The motor of a compressor may be installed internally or externally depending on the design of a water chiller.


The condenser removes the absorbed heat from the refrigerant that it picked up in the evaporator. With water type condensers, the water is cycled continuously between the cooling tower, where the heat is released, and the condenser. The refrigerant is contained in a set of pipes against which the water that collects the heat passes.

Expansion Valve

The expansion valve receives the refrigerant that is under high pressure from the condenser. The pressure of the refrigerant has to be lowered before it can move on to the evaporator, which is the job of the expansion valve. As the refrigerant passes through the expansion valve, its pressure lowers to a point such that it can be vaporized in the evaporator. The expansion valve controls the flow of refrigerant according to the load on the evaporator.

There are several types of expansion valves that include capillary tubes, thermostatic, low side float valves, and constant pressure ones.


The evaporator collects the heat that it receives from the water that has cooled the process and moves it into the refrigerant such that it can be removed through the cooling tower. The water cools as heat is extracted by the refrigerant and is pumped back to the process to continue the cooling cycle.

Power Unit

The power unit supplies power to a water chiller. It can be mounted on the chiller or on a wall near the chiller. The power unit controls the flow of power to the chiller and has a starter, circuit breaker, speed controller, and monitoring device.

Control Unit

The control unit monitors the performance of the chiller and makes it possible to adjust various aspects of the chiller process. It has an alarm system that shuts down the system when there are errors or problems during operation. Modern water chillers have a building management system (BMS) that makes it possible to send data to the control unit in regard to temperature, pressure, and on and off status.

An essential part of the performance of a water chiller control unit is to gather data and critical information from all aspects of the chiller system. The data is centralized and examined for trends and helps in making decisions regarding chiller operation.

Benefits of a Water Chiller

Chillers are an essential part of industrial operations and are used to remove heat to create cold conditions for processes and equipment. The most common types of chillers are air cooled and water cooled where an air cooled chiller removes heat using fans while a water cooled chiller uses water. Both types have their benefits that need to be considered when making the decision to purchase.

The benefits of a water chillers are:

Long Working Life

Water chillers are housed inside a building away from the elements, a factor that gives them a long working life. The fact that water chillers remain inside further enhances their use since they can be used by companies that do not have access to outdoor space.


Water chillers work quieter than air chillers due to the fact they do not have the ducts and vents that air chillers do. The flow of water does not create the expansion and contraction noise that air does, which is important for the use of chillers in hospitals and schools.


With industrial operations and applications, efficiency is important since it guarantees the quality of a product and cost savings. The process that water chillers use to transfer and remove heat is efficient and energy saving. Water is continuously used and recycled removing the need for depending on the city water supply.

Equipment Protection

Water chillers are designed to protect valuable equipment, which cuts down on repairs and maintenance. They operate year round, regardless of the weather, and are dependable in all kinds of environments. Water chillers eliminate heat from spot welders, injection molding, and laser cutting processes. They can be used with any application that requires the limitation and removal of heat.

Choosing the Proper Water Chillers Manufacturer

To make sure you have the most productive outcome when purchasing water chillers from a water chiller manufacturer, it is important to compare at least 4 to 5 manufacturers using our water chiller directory. Each water chiller manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information.
