RB211 Gas Turbines

for oil & gas applications

energ

Reliable, proven power

The RB211 gas turbine package matches the technologically advanced Rolls-Royce gas generator with the efficiency of the RT56, RT62 or RT61 power turbine. The aeroderivative industrial design has demonstrated outstanding reliability, with hundreds of RB211 gas turbines installed worldwide, with 12 million hours operating experience.

Delivering high availability with ease of maintenance, the rugged RB211 is well suited for a variety of power generation and mechanical drive applications, including harsh environments and remote locations. Also available with Dry Low Emission (DLE) technology, RB211 gas turbine packages offer a wide range of power output options.
