Parameters Description
Temperature range is -20℃~+100℃, which can be extended to +135℃ according to the actual situation, and the temperature control accuracy is plus or minus 0.5℃. The equipment can control the flow and pressure independently while controlling the temperature, and different customized solutions are required for simultaneous control.
The tested object is attached to a test platform adapter.
The inside of the part was cooled and heated by an aqueous solution of ethylene glycol.
The test component needs to go through a specific temperature profile and record changes in temperature.
When performing a tolerance test, it usually takes an infinite loop.
Equipped with a powerful circulation pump while ensuring the delivery of highly viscous liquids.
Control the flow output with variable frequency regulation or proportional control valve to achieve high precision control total range 5%~100% adjustment.

Configuration Details
Working Principle
Temperature simulation for vehicle quality test: battery life test, fuel injector/motor test bench, airbag test, component test bench, etc. It can simulate the external environmental conditions in the climate chamber or replace the internal system, which can create the necessary actual temperature conditions for the test bench.
Test temperature of main test items of vehicle electronics:
IC test conditions for locomotives: -40℃~125℃, wind blowing, sun exposure, high vibration;
Instrument panel operation test test conditions: -40℃~85℃;
Motor controller test conditions: operating test temperature: 40 ℃ ~ 110 ℃;
Satellite positioning (GPS) Test conditions: high temperature operation test temperature: 85℃; low temperature operation test temperature: -40℃;
Compound vibration: -40℃~80℃;
Obviously the best solution is for the test house to have temperature simulation system equipment.
The model KRY -20℃~100℃ products can water-cooled and air-cooled.
