Coolant Chillers

Precision coolant chillers designed to maintain stable cutting-fluid temperatures, helping improve machining accuracy, tool life and consistency during continuous CNC operations.

Introduction

Atcorp offers precision coolant chiller solutions for CNC machining, grinding and other metalworking applications where cutting-fluid temperature directly affects machining accuracy and tool performance. The circulation-type design incorporates a built-in pump and connects directly to an existing coolant tank, while precise temperature control helps reduce thermal variation, coolant evaporation and bacterial growth.

Key Benefits

Reduced Thermal Variation
Built-In Circulation Pump
Lower Coolant Evaporation
Improved Coolant Quality
Easy Maintenance
Compact Construction

Why Choose Coolant Chillers?

During high-speed machining and material removal, significant heat is transferred into the cutting fluid. If coolant temperature is not controlled, thermal expansion, tool wear and dimensional variation can affect finished-part quality. A dedicated coolant chiller continuously removes this heat and maintains a stable coolant temperature, helping CNC machines maintain more consistent machining conditions.

A coolant chiller continuously removes heat from the cutting fluid and returns temperature-controlled coolant to the machine.

 

Step 1 – Warm Coolant Return
Heated cutting fluid returns from the CNC machine or machining process.

 

Step 2 – Coolant Circulation
The integrated self-priming pump circulates coolant between the machine tank and chiller.

 

Step 3 – Heat Transfer
The coolant passes through the SS304 shell-and-coil heat exchanger.

 

Step 4 – Refrigeration
The refrigeration circuit extracts heat from the coolant.

 

Step 5 – Heat Rejection
The air-cooled condenser releases the extracted heat into the surrounding environment.

 

Step 6 – Temperature Regulation
Hot-gas-bypass control regulates cooling output to maintain the required coolant temperature.

 

Step 7 – Cooled Coolant Return
Temperature-controlled coolant flows back to the existing machine tank.

 

Step 8 – Continuous Cooling
The cycle continues throughout machining to maintain stable cutting-fluid temperature.

Stable ±1°C Temperature Control

Maintaining coolant within approximately ±1°C of the set point helps reduce thermal fluctuations during machining.

 

Improved Machining Accuracy

Stable cutting-fluid temperature helps minimize thermal expansion of the workpiece and supports tighter dimensional control.

 

Better Tool Life

Controlling coolant temperature helps reduce excessive thermal stress on cutting tools during high-speed machining.

 

Reduced Coolant Evaporation

Temperature-controlled coolant can reduce evaporation losses compared with uncontrolled open-tank operation.

 

Reduced Bacterial Growth

Stable coolant temperatures can help reduce bacterial growth, decomposition and unpleasant odours.

Built-In Circulation Pump

The integrated pump allows the chiller to connect directly to an existing coolant tank without requiring a separate circulation pump.

 

Easy Heat Exchanger Cleaning

The SS304 shell-and-coil heat exchanger can be disassembled for easier cleaning and maintenance.

 

Compact & Mobile

Tall-boy construction and caster-mounted design make the unit practical for machine-side installation and relocation.

Frequently Asked Questions

Find answers about coolant chillers, CNC coolant temperature control, cooling capacity, installation, maintenance and machining applications.
A coolant chiller is a temperature-control system designed to remove heat from water-soluble metalworking fluids used in machining and grinding. Maintaining stable coolant temperature helps support machining accuracy, tool life and production quality.
High spindle speeds and rapid material removal generate heat that transfers into the cutting fluid. Uncontrolled temperature changes can contribute to workpiece thermal expansion, tool wear and dimensional variation.
The referenced GCC series supports a liquid operating temperature range of 15°C to 35°C, with temperature control precision of approximately ±1°C.
A conventional tank primarily stores coolant, while a coolant chiller actively removes heat and maintains the coolant at a controlled temperature. This is particularly valuable for high-speed and precision machining where coolant temperature affects dimensional stability.
Yes. The circulation-type configuration is designed to connect to an existing coolant tank using the integrated pump and simple hose connections, reducing the need for additional equipment.
Yes. Atcorp can help Indian manufacturers evaluate machine type, coolant volume, heat load, required temperature, flow rate and operating conditions to identify and supply a suitable coolant chiller solution.
