The duct structure of Walk-In environmental test chamber has gained a patent for invention. The duct structure ensures that the temperature in each testing area of the test chamber is uniform, thus guaranteeing higher test accuracy.
Oil separator and oil returning and shunting device: The oil contained in the high-pressure steam discharged by refrigeration compressor is separated to ensure safe and efficient operation of the refrigeration system. Oil returning and shunting device (Simplewell’s patented technology) is mainly used to ensure the long-term operation of compressor or operation in high temperature. It prevents compressor failure or shortening of compressor service life due to lack of oil.
