Specification Sheet
  • Cooling Capacity: 0.5-110kW

Oil chillers use air-cooled refrigeration to regulate oil temperature in industrial machines and keep it within a stable temperature range even during continuous operation. They circulate refrigerant through an internal cooling cycle that removes heat from the oil using a heat exchanger, which helps keep operating temperatures stable and protects equipment from thermal stress.

Applications
Oil chillers are used in machining and precision manufacturing to maintain stable oil temperature during operation, including the following applications:

  • Metal cutting equipment such as CNC machines, machining centers, lathes, milling machines, grinders, broaching machines and EDM systems for spindle and hydraulic oil cooling to maintain machining accuracy and extend equipment life.
  • 3C electronics and brittle material processing such as drilling machines, glass processing systems, quenching machines, liquid-cooled connector machines and chip packaging equipment to keep processing conditions stable and protect component performance.
Main Components
Evaporator

Evaporator
Absorbs heat from the cooling fluid as the refrigerant changes state, which lowers the temperature of the fluid in the chiller.

Compressor

Compressor
Increases the pressure and temperature of the refrigerant gas so it can release heat effectively in the next stage.

Condenser

Condenser
High-pressure superheated refrigerant vapor from the compressor enters the condenser, releases all the heat absorbed during the cycle to the surrounding air, and then turns back into liquid.

Expansion Valve

Expansion Valve
It reduces the pressure of the high-pressure, normal-temperature refrigerant liquid, turning it into a low-temperature mixture that enters the evaporator to absorb heat and complete the cooling cycle.

Other Components
ON/OFF Control System

ON/OFF Control System
It provides direct cooling by circulating industrial oil to absorb heat from high-temperature areas of the equipment and reduces local heat buildup and temperature differences.

PID Control System

PID Control System
It adjusts machining temperature in real time to match ambient conditions, keeping it within ±0.5°C and reducing heat-related deformation and expansion.

AC Variable Frequency Control System

AC Variable Frequency Control System
It connects with a remote control center through MAX485 communication and enables precise temperature control with an accuracy of ±0.1°C.

Customization Notes: The material of the heat exchanger and sealing parts must be selected based on the cooling medium. The pump also needs to be customized according to the flow rate, viscosity, and pressure of the cooling medium.
