Coolant Chiller-An Ultimate FAQ Guide by TopChiller.

What is a Coolant Chiller?

A Coolant Chiller is a soothing device that monitors and stabilizes the temperature of the coolant by eliminating the extra heat absorbed by it during machine processing.

The maintenance of the cooling temperature of the coolant is crucial for maximum working of the chiller. An electromechanical process is used for this purpose.

The chilled coolant is then circulated in the chiller to offer maximum heat exchange. The lower the coolant temperature, the greater the heat transfer because of the increased temperature difference.

It reduces the vibrations and noises produced by thermal changes and also increases thermal stability.

Coolant Chiller is primarily used in water-soluble coolants used for grinding and cutting. NC grinding machines, plastic industry, ceramic industry, and other material synthesizing industries use it for added thermal stability and higher efficiency.

What are the Significant Components of a Coolant Chiller?

Control Panel

The primary purpose of the control panel is to control and operate your Coolant Chiller, including the starting up, maintenance settings, or powering off.

Pneumatic System

The pneumatic system is installed to manage and properly control the pressure within the unit.

Its strong connection with the control panel enables the user to operate the pressure system efficiently.

Electronic Unit

The electric unit supplies the energy or power for this whole cooling system to work. This power is adjustable with the help of different parts of the electric unit.

Refrigeration Unit

The refrigerant unit is responsible for supplying the refrigerant, which has one of the significant roles in absorbing extra heat.

You will find a refrigeration tank in the refrigeration unit, which holds up the reservoir refrigerant.


Compressing the refrigerant is done by the compressor, allowing it to move quickly at high speed.

Centrifugal, screw, and scroll compressors are commonly used compressor types used in Coolant Chillers.

Condenser Unit

The condenser unit deals with heat dissipation while the refrigerant is turned into a liquid from the gaseous state.

The refrigerant comes into direct contact with chilled air currents or water currents. The heat from the refrigerant is absorbed as it flows through the coils.

This heat can be later transferred to the environment or can be used for any other process.


The heat that has been removed from the coolant can be used here for converting the liquid refrigerant into a gaseous form.

The surface area of the evaporator must be more significant. It allows greater evaporation as the surface molecules are more in number, and they tend to break free from the rest of the refrigerant as they gain energy.

Expansion Valve

The speed and pressure of the refrigerant have to be controlled so that it can be managed and fed to the system according to the requirement.

It allows the proper use of the refrigerant for maximum advantage.

Coolant Chiller Control Panel

How Does the Coolant Chiller Work?

The Coolant Chiller has a cyclic working mechanism that is repeated to obtain the highest efficiency and allow minimum refrigerant usage.

The working mechanism consists of several phases, which are explained below:

Preparation Phase

This phase ensures that the chiller is in the optimum working stage. It is done by checking all the connections and inspecting all the components to see if they are in place.

You must check the refrigerant level in the reservoir to ensure proper supply throughout the cycle.

Now you have to set the values on the control panel according to the requirement of your application.

The temperature, pressure, humidity, and other external conditions must be maintained, and therefore you should set a narrow range for these quantities.

Once you are sure about all the preparations, press the start button to initiate the release of the refrigerant from the reservoir.

Compression of the Refrigerant

As the refrigerant flows from the storage tank to the compressor, high pressure is applied to reduce the volume. It also decreases the intermolecular spaces between the molecules.

In this way, you can increase the velocity of the molecules to direct them into a specific orientation. Various compressors with particular properties can be used in a Coolant Chiller.

Absorption of Heat

The high-velocity refrigerant flows around the pipes and tubes under high pressure. These tubes contain hot water, which has become hot due to the heat transfer from the coolant of the chiller.

The residence time of the refrigerant is increased in the evaporator as it absorbs heat and converts from a liquid to a gaseous state.

Elimination of Heat

When the refrigerant has had enough heat loads, it starts flowing directly to the condenser from the evaporator.

Cold water and air currents flow in direct contact with the refrigerant in the condenser. The temperature difference allows maximum heat transfer.

As the refrigerant has lost the heat, it converts back into a liquid state. The conversion of gas into a liquid is called condensation.

Refrigerant Setting

The velocity and press of the refrigerant must be controlled as it flows through the system.

The expansion valve allows you to brain this function by releasing only a certain amount at one time, that too, with the set pressure and speed.

The whole cycle runs again when the refrigerant directly goes to the compressor in substantial parts.

What are the Advantages of a Coolant Chiller for your Industry?

Some of the significant advantages of a Coolant Chiller are listed below:

Standard Setup

It will aid in maintaining temperature and pressure and maintaining the desired level of water in standard design.

Coolant Chiller Applications

How Does High Temperature Affect your Coolant Chiller?

The high temperature for long hours can negatively affect your Coolant Chiller and dramatically affect efficiency. Here are a few ways in which it causes damage to the system:

Scrapped or Rejected Components

High temperatures tend to melt the sensitive parts of the components made up of any low melting point material.

With these parts melting, the components lose their function and directly affect the chiller’s efficiency as they disrupt the refrigeration cycle.

Reduction in Service Life

High temperatures decrease the chiller’s service life by denaturing the main components.

The valves and the tube network also undergo degradation leading to a lag in the normal flow.

Wastage of Resources

If the coolant is exposed to high temperatures for long hours, it might evaporate. It is impossible to restore all the evaporated coolant, which gets wasted.

Wear and Tear

Due to high temperatures, the system parts that run against each other tend to wear out and lose their function.

The shape and architecture details are lost, and therefore the function is not performed correctly.

What is the Most Suitable Refrigerant for your Coolant Chiller?

There is a wide variety of refrigerants that can be used in a Coolant Chiller. However, the most preferred and widely used is glycol.

Glycol is a water-soluble compound with excellent dissipation properties and high heat absorption.

The mixture of glycol is more efficient than the glycol alone. It goes well with the properties of a suitable refrigerant which are as follows:

  • It must not damage the ozone layer like the chlorofluorocarbons.
  • It shall be environmentally friendly.
  • The cost should be within the range of the user.
  • It shall have no adverse effects on the system.
  • There should be the maintenance of a proper refrigerant level in the system.

What is a Stand-Alone Type Coolant Chiller?

In a Stand-Alone Type Coolant Chiller, an inbuilt pump is already installed. The function of this pump is to remove fluid from the coolant tank that is present remotely.

This happens when this pump gains energy. Next, it pumps the fluid back to the tank by passing it through the evaporator installed in the unit.

In the next step, the temperature of the fluid making its way inside the chiller is sensed by the temperature controller. This controller also works for controlling and maintaining the refrigeration effect.

As a result, it helps maintain the required temperature of the fluid present inside the tank. It would be best to consider here that you must install the cooler nearest to the tank.

Stand-Alone Type Coolant Chiller

What are the Different Compressor Systems for your Coolant Chiller?

The primary function of installing a compressor in your Coolant Chiller is to lower the volume of the gas and increase its pressure.

It helps transport the fluid through the pipes and reduces fluid pressure.

Low temperature and low pressure of the fluid are achieved by removing vapors from the evaporator before sending the fluid to the condenser.

In the case of a Coolant Chiller, you have three different options for choosing the best compressor system.

The essential function of all these compressors is the same, but there is a slight variation in their construction and working mechanisms.

Scroll Compressor

There are orbiting as well as fixed scrolls involved in the main construction of this compressor.

The purpose of installing both these scrolls is to help efficient refrigerant compression. These compressors are best to be used in applications in schools, offices, and clinics.

Screw Compressor

Next comes the screw compressor, which involves the installation of two rotors for its working.

These rotors help compress the refrigerant and turn it into a high-pressure liquid from a low-pressure one.

The essential purpose of these rotors, also called screws, is to entrap the refrigerants before converting high-pressure refrigerants.

Centrifugal Compressor

As the name says, a centrifugal compressor uses the principles of centrifugal force for the compression of refrigerants.

The ideal situations for using a centrifugal compressor include medium to high capacity applications.
