The cooling, low temperature, constant temperature and damp heat of the equipment provide the required cooling capacity. According to the different test states of the equipment, the refrigeration system will automatically start to provide cooling capacity for the corresponding test process, so as to meet the performance index of the equipment.

Air Tightness Testing Equipment For Auto Air Conditioning Compressor， places the test piece in the vacuum chamber and connects the test piece interface with the quick connector in the vacuum chamber. After the door of the vacuum chamber is closed, the system can automatically complete the whole procedure of large leak and strength detection, evacuation, helium filling, medium leak and micro leak detection, and helium recovery. The production cycle is fast and the leak detection accuracy is high.
