Start-up sequence of cold dryer and air compressor

The starting sequence of the cold dryer and air compressor is: first open the cold dryer, then open the air compressor. At the same time, the shutdown sequence is opposite to the startup sequence, that is, the air compressor is closed first, and then the cold dryer is closed.

During the operation, it is necessary to pay attention to prohibiting frequent opening and closing of the cold dryer to avoid burning the compressor motor. When the equipment is shut down, the manual drain valve should be opened to drain the condensed water clean, so as to avoid the freezing of the condensed water causing damage to the refrigerated dryer when the ambient temperature is too low. In addition, after the stable operation of the cold dryer, it should be observed whether the value of the refrigerant pressure gauge is within the normal range.
