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.
