Designed to deliver energy savings

A new range of variable-speed air compressors from FPS Compressors uses advanced techniques to deliver energy savings.

Called the Galileo range and manufactured by Power System Group, the new machines use direct drive, permanent magnet motors and sophisticated controls.

The new Galileo compressors are based on the PS-DV Series platform of variable-speed compressors with efficient compressor air end, direct drive and sophisticated controls. The adoption of a new generation permanent magnet motor however brings further gains in energy efficiency.

The company says the specially designed synchronous motor, using permanent magnets provides several benefits over asynchronous motors.

These are said to include the avoidance of extra field current normally required to generate the magnetic field in the rotor, very high flux density, high and constant torque, high power factor and efficiency across a wide range of operating speeds.

Sophisticated controls include the capability of connecting to external control, monitoring or visualisation software or even business management applications via a LAN, serial interface or web-connected modem. This allows remote computer-based monitoring and diagnostics functions to be implemented.

There are more than 25 models in the Galileo range, offering a wide range of performance - from 9 to 180kW, - with operating pressures between 7.5 and 13 bar, and with capacities that range from 1570 to 30,000L/min.
