Five

High and low pressure rapid balance There is a pipeline connecting the high and low pressure sides of the machine head. Controlled by a solenoid valve. Before the compressor is started, the solenoid valve opens and the high and low pressures are quickly balanced, thereby avoiding excessive shaft torque, protecting the motor, and reducing inrush current.

Six fault memory functions There is a fault memory module in the electrical control cabinet of this unit. It can automatically reset and start, keep the fault light flashing, and record the type of fault, which greatly shortens the fault diagnosis time. Configuration of seven units
