Answer: In order to drain the condensed water in the cold dryer out of the machine in a timely and thorough manner, the simplest way is to open a drain hole at the end of the evaporator, so that the condensed water generated in the machine can be discharged continuously, but its disadvantages are also obvious. Because while draining, the compressed air will also be discharged continuously, causing the compressed air pressure to drop rapidly, which is not allowed for the air source system. Although it is feasible to manually drain water at a fixed time with a hand valve, it requires additional manpower and a series of management troubles. Using an automatic drainer can automatically drain the accumulated water in the machine at a fixed time (quantity).
