Micro-renewable hot dry machineMicro-hot renewable Adsorption compressed air dryer is the use of PSA, the principle of renewable heating, so that compressed air flows through the two alternate adsorption tube, that is, when a cylinder pressure in a state of moisture adsorption, and the other cylinder from gas pipeline will be re-heated dry and access to low-pressure gas, the moisture desorption desiccant. It has no hot dryer regeneration of simple structure, high degree of automation and renewable hot dryer less air consumption, in-depth the advantages of desorption. At the same time, in order to avoid the structure of renewable hot huge disadvantage of large power
