PLC with VFD

SMOOTH START-UP

The VSD is soft staring, enabling controlled acceleration and deceleration which reduces stress on mechanical components and enhances system reliability. This results in increased life of the compressor.

SMART CONTROL

VSD keeps desired line pressure constant, adjusting automatically according to system air consumption by varying motor speed. The Compressor only consumes the energy needed to produce the compressed air required by the system. In fixed speed if compressor operates on no load, energy is wasted while no work is performed. VFD with PM motor saves up to 39% energy compared to conventional cycling.

A fixed speed compressor operates on a load-unload band of at least 10 PSI around the working pressure, wheres with VSD Compressor can be operated within a band of 2 PSI. For every 2 PSI reduction in operating pressure, there is 1% power saving.
