Features and Advantages:

Coolant Chiller manufactured by TopChiller is of particular importance for its top features and benefits executing for different applications as:

  • The hot coolant of processing machines is being cooled by transferring a heat exchanger through a filter. The heat exchanger absorbs all of its additional heat by refrigerant and transfers it back for machines’ cooling.


  • During machine processing, heat is produced in large amounts from their rotating spindles. The heat, damaging for machines, is being liberated by chilled coolant circulation around spindles increasing machine service life.


  • Microprocessor temperature controller is also integrated, configuring the inspection of coolant temperature coming from machines before it enters the evaporator. In this way, the temperature of the coolant is peculiarly regulated as pre-requisites.


  • All of the waste heat accumulated from machine coolant is needed to discard from the system. Chilled water or fresh air is provided to circulate over condenser coils. It absorbs refrigerant to heat and cools it for the next cycle.


  • Prevents from parts variation of machine that occurs due to thermal changes configured by chilled water supply provided by the cooling tower and water pump.

You will inspect the machine and ensure that all the components are in the right condition.

Apart from that, you must also refill the refrigerant reservoir to allow the proper supply of the key factor.

As soon as that is complete, you will begin the process by configuring the machine from the control panel.

You will press the start button which will trigger the refrigerant release from the refrigerant storage tank.

2) Compression of the Refrigerant

One of the fundamental operations that lead to the cooling of coolants is the compression of the refrigerants.

In other words, the refrigerant will flow from the storage tank to the compressor which will increase the pressure.

You can opt for one of the numerous types of compressors to increase the pressure and speed of refrigerant flow.

3)  Absorption of Heat

Here, the refrigerant moving at high velocity under high pressure will flow over tubes and pipes that contain hot water.

The tubes and pipes have hot water which contains the heat that was released by the coolant you intend to cool.

So, you will increase the residence time of the refrigerant within the evaporator as it absorbs the heat.

It will change state from liquid to gas due to the absorption of heat from the hot water.

4) Elimination of Heat

As soon as the refrigerant has enough heat load, it will flow from the evaporator straight to the condenser.

While in the condenser, it will encounter a stream of cool water or air which will eliminate the heat.

Your choice of coolant chiller will determine the type of chiller which can either be air or water.

The refrigerant will release the heat into the flowing water or air and then condense it back to a liquid state.

5) Refrigerant Setting

With the same velocity, the liquid refrigerant will flow to the expansion valve which restores it to its original settings.

Implying that, you will set the expansion valve to reduce the speed and pressure of the refrigerant accordingly.

It will then deliver the refrigerant straight to the compressor in specific quantities and the whole process begins once again.
