4 Pole Air Cooled Generators

Built upon 145 years of generator expertise, BRUSH offer customers bespoke turnkey products engineered to perform, built to last and offered with comprehensive lifetime Service support.

Overview

The 4-Pole DG generator range is designed to be driven by gas or steam turbines with outputs from 10 to 75 MVA.

With over 750 active installations, the time-proven DG range built in a European ISO accredited site are specified by leading geothermal, public utility, co-generation (CHP), industrial and offshore applications operators.

Manufactured from a one-piece forging of high-quality alloy steel, providing a minimum of 25 years’ service life, these units are based on a modular construction method that can be easily adapted to meet any turbine design. Units are factory tested, to reduce on-site testing and commissioning time.

The continued success in both gas turbine and steam turbine power generation can be attributed to BRUSH’s ability to meet the demanding interface requirements of turbine manufacturers, coupled with competitive prices and keen deliveries.
