Electronic Governors for Turbines

At Alberta Governor, we carry Woodward electronic governors for turbines. As a Woodward Authorized Independent Service Facility, we are able to provide repairs and service for electronic governors. As a Woodward RTR (Recognized Turbine Retrofitter), we are able to service in our shop or on site, as well as provide assistance during the commissioning stages of a rebuild.

We carry the following electronic governors for turbines:
