Application of variable frequency technology
CMN variable frequency screw air compressor can change the rotating speed precisely according to the air consumption in the case of the stable exhaust pressure, which makes the air compressor only produce the required air capacity. The purpose of the energy saving, thus it can be achieved and saved energy exceeds the cost of air compressor itself.
Efficient power returns
The displacement of the variable frequency compressor can combine with the air consumption perfectly to avoid the loss of the unloading power completely. The 0.2MPa pressure is reduced and it makes the machine save 14% energy directly.
Arbitrary pressure set, and keep constant pressure supply
The machine can be satisfied the pressure setting by the users within 0.4-1.2MPa(Note: the maximum pressure shall be confirmed when purchase the machine) and the machine unit always keeps the air supply of constant pressure± 0.01MPa. When the air consumption increases, the machine unit will improve the rotating speed automatically; when the air consumption decreases, the machine unit will reduce the rotating speed automatically to keep the pressure supply of the system constantly.
More reliable operation
The soft start of variable frequency prevents the impact of the power grid and avoids the mechanical impact from the machine itself. There is no contactor, free of electric contact failure and the operation is more stable and reliable.
