Chillers are an essential part of many industrial processes. But what is a chiller, and how does it work?

This blog post will discuss the basics of industrial chillers and what they do. We will also explore some of the different types of chillers that are available on the market today.

If you are considering installing a chiller in your factory or business, this blog post is for you!

What is a Chiller?

A chiller is a piece of equipment used to cool a fluid by removing heat from it.

The fluid may be one of the following:

  • Liquid
  • Gas
  • A mixture of the two

Chilling is often used to produce ice, freeze water, or lower the temperature of a substance.

How Does a Chiller Work?

A chiller works by circulating a coolant throughout the system. The coolant absorbs heat from the liquid or gas and transports it away to reduce the temperature of what is being cooled.

The most common type of chiller uses a refrigeration cycle, which takes advantage of thermodynamic principles to move heat energy out of what is being chilled and into the atmosphere.

Heat Absorption

For a chiller to be effective, it must be able to absorb heat from the fluid or gas that is being cooled. This is done by passing the coolant through an evaporator coil, which absorbs heat energy from what is being chilled and turns it into vapor form.

Vapor Compression

The vapor then passes through a compressor, where it is compressed and condensed back into a liquid form.

The condensed liquid then passes through a condenser coil, which releases the heat energy into the atmosphere. It is essential to understand how to save energy while using this equipment.

What Makes Up a Chiller?

A typical chiller is composed of several significant components.

These components consist of the following:

  • Condenser
  • Compressor
  • Evaporator
  • Expansion valves
  • Power unit
  • Control unit
  • Water boxes

Condenser Fans

Condenser fans move the heat energy from what is being chilled into the atmosphere.

The fans are designed to ensure that the condenser coils are cooled efficiently and remain in an optimal temperature range.


The compressor is responsible for compressing the refrigerant vapor back into a liquid state.

The compression process creates pressure, which helps to move the heat energy out of what is being chilled.


The evaporator coil absorbs heat energy from what is being cooled and turns it into vapor form.

This process helps to reduce the temperature of what is being cooled.

Expansion Valves

Expansion valves are used to control the flow of refrigerant in the system. They are essential for ensuring that the system remains working efficiently.

Power Unit

The power unit provides energy to run the compressor and other components in the chiller.

This typically consists of an electric motor or a gas engine.

Here are some tips to reduce gas usage for your business using an industrial chiller.

Control Unit

The control unit regulates all of the components in the chiller, ensuring that they all work together efficiently.

The control unit enables the chiller to adjust the temperature of what is being cooled as needed.

This component is essential for ensuring that the chiller works correctly and efficiently. Without it, the chiller may not be able to achieve the desired temperature.

Water Boxes

The water boxes help to store and circulate chilled water throughout the system to maintain a consistent temperature.

The box is made up of two parts: an inlet and an outlet. The inlet is where the water enters the box, and the outlet is where the water exits.

Uses for Industrial Chillers

Industrial chillers can be used for a variety of purposes in many industries.

Get started with one today by looking into industrial chiller manufacturers, which produce a variety of chillers that can be used in various industries.

Some uses of this equipment include the following:

  • Metal Finishing
  • Food processing
  • Injection molding
  • Space cooling

Metal Finishing

Chillers are used in the metal finishing industry to cool metal parts and components during manufacturing.

Metal Finishing is a process that uses industrial chillers to cool down metal parts. The metal parts are then dipped in a coating that will protect them from rusting or corroding.

The industrial chiller helps to cool the metal parts quickly and evenly so that the coating will stick to the surface. Without the industrial chiller, achieving a consistent finish on the metal parts would be difficult.

Food Processing

Food processing is used for industrial chillers. In particular, chillers are used to control the temperature of food products as they are processed. This helps ensure that the food is not spoiled and meets all safety requirements.

Also, chillers can create certain textures and flavors in food products. For example, ice cream is made by churning a mixture of milk, cream, sugar, and flavorings while it is chilled.

This process creates a smooth texture and prevents the formation of large ice crystals, which makes the ice cream taste icy.

Injection Molding

Chillers are also commonly used in the injection molding process to cool heated plastic parts and components before they are removed from their mold.

This helps to prevent any damage to the parts due to excessive heat.

Space Cooling

Chillers are also often used in large commercial and industrial spaces to provide cooling throughout the facility.

This helps maintain a comfortable temperature for staff, customers, and any equipment in the space.

Wrap Up

Chillers are an essential part of many industrial processes and help ensure that what is being cooled is correctly maintained at the right temperature. Understanding what a chiller is and what components make it up can help you to better understand how it works and how best to use it in your industry.

By understanding how they work and how they can benefit you, you can get the most out of your chiller and save energy and money.

Chiller FAQ

What is an industrial chiller used for?

An industrial chiller is used to cool air, liquids, and other materials in various industries. It consists of four main components: fans, compressors, evaporator coils, and expansion valves. 

What does an industrial water chiller do?

An industrial water chiller is used to cool liquids, such as water or glycol, to maintain a consistent temperature. It works by using a compressor and evaporator coils to move heat energy out of what is being cooled. 

What are the three types of chillers?

The three main types of chillers are air-cooled, water-cooled, and evaporative condensers. Each type uses a different method to remove heat from what is being cooled.

How much do chillers typically cost?

The cost of chillers can vary significantly, depending on the size and features of the unit. Generally, they range from around $3,000 to over $25,000. It’s essential to do your research before purchasing a chiller to get one that fits your needs and budget. 

What are the benefits of using a chiller?

Chillers offer many benefits, including energy efficiency, improved safety, and consistent temperatures. They can help to save money on energy costs by providing cooling when and where it’s needed most. Additionally, chillers help to reduce the risk of overheating, which could lead to dangerous scenarios.
