What’s Adsorption Drier Is Used for in Temperature Humidity Chamber Adsorption drier applied very widely in temperature humidity test chamber. Today I will make a brief introduction for this device. The function of adsorption drier is to make the compressed air filter and try to make the water inside the compressed air being adsorbed. Then the air comes out will have very less water (like nitrogen). When the chamber from low temperature to high temperature. Because the test specimen is a little cold. If the air inside the chamber is wet, the surface of the test specimen will have dew formation. If at this time, we input the dry air from the Adsorption drier, then it will dilute the water in the air, to make the air become dry, then at the surface of the test specimen, it will not produce condensation
