Invt Compressor Driver Gd300-21

GD300-21 (Compressor Driver)

Special driver for screw and fan drive for Screw Air Compressor application

Unlike traditional solutions, INVT GD300-21 series screw compressor machines have dual motor outputs. However, both screw and cooling fan motors are driven by independent PID control algorithms. In this way, optimum efficiency can be achieved in the energy consumption of the machine. It has an easy-to-use Turkish interface with touchscreen HMI display.

3 phase power range; 380-480 VAC

15-90[kW]
