2 Pole Air Cooled Generators

A leading industry authority in synchronous rotating machines, BRUSH has been providing generator expertise for over a century. From standard applications to highly customised solutions that meet the most demanding environments and operation conditions in the world.


The 2-Pole DAX generator range is driven by steam or gas turbine outputs from 10 MVA to 350 MVA. With over 3,500 active installations, the time-proven DAX range of generators built in a European ISO accredited site are specified by leading industrialists, EPCs and facility operators.

BRUSH generators are compatible with any turbine up to 350MVA including aero-derivative gas turbines, heavy frame gas turbines, steam turbines and turbo-expanders. 

BRUSH’s engineering team are recognised, world-leading experts in synchronous rotating machines and provide optimised generator selections to meet customers’ unique operating conditions.
