Your Professional CNC Chiller/ Water Cooling System Manufacturer and Supplier Over 20 Years

CNC water cooling systems or CNC chillers are specially designed and manufactured for cooling CNC spindles and CNC machines.

TopChiller® is a professional CNC cooling system and CNC chiller manufacturer for over 20 years.

More and more CNC machines involve high spindle speeds and fast material removal rates which generate a lot of heat.

This heat is directly added to the cutting fluid/coolant associated during the process. The high temperature is not advisable as it can cause many problems including rejected /scrapped components, reduced tool life, and coolant wastage due to increased evaporation.

CNC cooling systems and CNC chillers manufactured by TopChiller are used to maintain precise coolant temperature by rapidly rejecting the heat added during the machining process.

You will benefit by using our high-quality CNC cooling systems and CNC chillers:

*To prevent the main shaft of CNC working machinery from affecting the accuracy due to the change of oil temperature.

*CNC cooling system can prevent oil shock and oil deterioration, and keep the lubricating oil degree unchanged, to make the spindle operate stably.

*CNC cooling system adopts the body synchronous temperature control panel to make the oil temperature follow the room temperature to prevent the mechanical structure from thermal expansion and cold contraction.

*The CNC cooling system has the function of automatic fault detection and display and informs the CNC host of the fault condition through the computer online, to avoid the damage of the parts.

These cooling systems or chillers are used to operate with water as well as oil-based coolant fluids.

CNC cooling systems and CNC chillers designed at TopChiller are available in the following configurations: packaged type chiller, Dip in / Submersible type from cooling capacity 0.5KW to 48KW.

Our professional&skilled team is experienced in the demanding requirements for cooling CNC equipment and machinery and can assist you in selecting the best CNC cooling system or CNC chiller for your application.

CNC Chiller-The Ultimate FAQ Guide by TopChiller.

What Is CNC Chiller?

CNC Chiller is a cooling device that works on the refrigeration principle to cool CNC machines for working efficiently.

The heat from rotating spindles of the CNC machine is firstly collected and finally discharged from the system by chilled water or ambient air over the condenser.

Constant cooling supply to spindles by CNC Chiller ensures the long service life of CNC units.

What are the Main Components of a CNC Chiller?

Hermetic Rotary/Scroll Compressor

It provides compression pressure for an efficient flow of refrigerant.


Water-cooled condenser for heat dissipation from CNC machines.

(PHE) Plate Heat Exchanger:

It configures the collection of heat from the spindle of CNC machines.

Water Tank and Water Pump

Tank for chilled water storage and water pump to enforce water flow over refrigerant for cooling.

What is the Working Principle of a CNC Chiller?

CNC Chiller works on refrigeration, compression, heat flow, and phase change principle.

The refrigerant that is installed inside a CNC Chiller, absorbs heat from CNC machines, changes the phase from liquid state to gaseous state.

Gaseous refrigerant gets compressed by the compressor and moves towards the condenser for heat dissipation.

How does CNC Chiller Perform its Function?

CNC Chiller works to produce a cooling effect for CNC machines in the following steps:

Step 1:

Scroll compressor applies a compression force over gaseous refrigerant for fluent flow.

Step 2:

The water-cooled condenser dissipates heat from the refrigerant and reduces the temperature by applying pressure.

Step 3:

The condensed refrigerant absorbs the heat dissipated by CNC spindles and produces a cooling effect.

Step 4:

By cooling the oil of the machine, the refrigerant changes its phase and again move towards the compressor for recycling.

What is the Cooling Capacity of a CNC Chiller?

The range of a chiller at which it can discharge heat from a heated fluid is called cooling capacity.

The cooling capacity of a CNC Chiller ranges from 500Kcal/hr to 15000Kcal/hr.

What is the Temperature Control Range of a CNC Chiller?

At a specific set point of temperature, a CNC Chiller performs its function efficiently.

25°to 40°C is the best temperature control range for its working.

How can a CNC Chiller Increase the Service Life of your CNC Machine?

A CNC Chiller increases the service life of a CNC machine by discharging extra heat produced by spindle rotation.

The temperature controller regulates the temperature at a specific set point suitable for the best working of the machine.

Protection devices maintain pressure, power supply, and pressure configuring an increased service life.

What are Some Leading Applications of a CNC Chiller?
