• Multi-unit sequent control enables air compressors to operate in different combinations
• Local or Remote control functionality

Hybrid Permanent Magnet Motor

A major feature of the hybrid permanent magnetic motor is its detachable motor stator winding, allowing it to be replaced on site. The second feature is its small size and high power, the volume is only 33% of the conventional variable frequency motor , allowing it to be directly connected with the male rotor of the air end for driving. Finally, the unique layout eliminates the use of wear parts and motor bearings in the motor.

• High efficiency of up to 96%, while an asynchronous motor of the same power only operates with an efficiency of up to 93%.
• Efficiency difference increases as the load decreases, and the rotor does not need to be electrically excited, resulting in small inductive resistance and high power factor.

Reliability. Performance. Value.

The Gardner Denver variable speed drive/motor/compressor combination and the controller, are designed to meet the varying demands of your system at the lowest possible specific power, which benefits you in the form of energy cost savings.

Direct energy savings of up to 35%

The precise pressure control of the HPM compressor allows for a tighter pressure band and a lower average working pressure, resulting in reduced energy consumption.

Indirect energy savings

The lower system pressure obtained by GDK – HPM results in up to 10% additional yearly savings:

• Lower energy consumption of (other) base load machines
• Leakage loss is significantly reduced: e.g. leakage at 6 bar is 13% lower than at 7 bar
• Most compressed air applications consume less air at a reduced pressure
