Governors are very critical in application and forms the major control units of a Gas Enginator. The major brands of Governors used are HEINZMANN , WOODWARD and COMAP governors, Types are  normally used

1. Heinzmann for DEUTZ MWM TBG620 , TBG616 and TBG632 series. Also TCG 2020 and TCG2032 also uses Heinzmann actuators and Governors. But the TEM-EVO uses its proprietory CPU cards for speed control and load control.
2. Other gas engines like MITSUBISHI , Jenbacher and Wartsila gas generator uses WOODWARD 2301A or 701A series for Mitsubishi and Heinzmann for Jenbacher J620 and J616 Gas Engines Generators.
3. We have various Simulators and REALTIME simulators for Governor calibration and governors diagnosis. We have programmers and Hand held controllers for WODWARD and HEINZMANN governors. Also we have Function frequency generator for Cranking simulation of Gas Generators during Installatioon and Commissioning phases of Power Plants.
