VSD ENERGY-SAVING TECHNOLOGY

MAIN MOTOR INVERTER
DESIGN CONTROL

Stable constant pressure

The SCR GV compressor’s fluctuating variable speed range provides a stable constant pressure control that reduces power consumption. SCR’s exclusive inverter and energy-saving logic control can optimise energy savings, regardless of the load condition. They can react to pressure changes to quickly maintain pressure fluctuation at ±0.01 MPa.

INOVANCE VARIABLE SPEED DRIVE (VSD)

Inovance has been used on SCR VSD compressors in Australia for over ten years. Its proven reliability in some of the country’s toughest environments and its innovative energy saving features make Inovance the perfect choice for the GV series.
