A compact precision chiller continuously removes heat from process water and returns temperature-controlled water to the connected equipment.

 

Step 1 – Warm Water Return
Water carrying heat from the machine enters the chiller.

 

Step 2 – Heat Transfer
The process water passes through the plate heat exchanger.

 

Step 3 – Refrigeration
The refrigeration circuit extracts heat from the circulating water.

 

Step 4 – Heat Rejection
The air-cooled condenser releases the extracted heat into the surrounding environment.

 

Step 5 – Temperature Control
Hot-gas bypass control regulates cooling output to maintain the required water temperature.

 

Step 6 – Chilled Water Circulation
The integrated pump returns cooled water to the connected machine.

 

Step 7 – Continuous Cooling
The closed-loop process repeats to maintain stable equipment temperature.

 

The smaller models use rotary compressors, while the GKS2200B-V uses a scroll compressor. The system also incorporates an integrated water tank to provide additional thermal stability during short load variations.

Compact Machine-Side Cooling

The compact format makes these chillers suitable for individual machines, laboratories and smaller workshops where plant-scale cooling is unnecessary.

 

Precise ±1°C Control

Temperature control within approximately ±1°C helps protect sensitive equipment and maintain process consistency.

 

Small Cooling Capacity Options

With models from 1.8 to 8.7 kW, customers can select cooling capacity closer to the actual machine heat load.

 

Integrated Water Tank

An in-built water tank provides thermal storage and simplifies the closed-loop cooling arrangement.

 

High-Pressure Pump Options

Integrated centrifugal and multistage centrifugal pump configurations provide dependable circulation, with applicable models capable of pressures up to approximately 6 bar / 60 m head.

 

Durable SUS316 Heat Exchanger

The brazed plate heat exchanger uses SUS316 plates for robust heat transfer and durability.

 

Easy Mobility

Caster-mounted construction allows the chiller to be positioned conveniently near the equipment it serves.

 

Simple Maintenance

Dust-filter mesh, water-level indication and pressure gauges make routine monitoring and maintenance easier.
