Centrax Limited is a privately owned company based in Newton Abbot, Devon in the South West of England.

The company was founded in 1946 by Richard H H Barr OBE and the late Geoffrey R White after both worked with Sir Frank Whittle in the Power Jets Design Team during the 1940's - pioneering the use of the gas turbine for use in aircraft propulsion.

Centrax supplies gas turbine-driven generator sets, incorporating Siemens industrial turbines in the 3.9 to 66 MW range, for the power generation, CHP and stand-by markets worldwide.
