Gas Valve Unit

  • The GVU is a stand-alone auxiliary and regulates the gas supply under all required conditions for engine operation. It is designed for natural gas operation and is therefore equipped with special safety devices. Within the GVU, the incoming natural gas is separated into ignition and main gas. Special sensors and valves enable the pressure and leakage detection to shut-off both lines. The equipment of the gas valve unit shown in the picture above is the variant according to European standard.

Cooling water and lube oil combined module

  • The combined module includes the main components of the cooling water system and the lube oil system and is located in the power house. It provides the engine with a sufficient amount of cooling water and conditioned lube oil. The selection of the appropriate module is made by Caterpillar Motoren GmbH & Co. KG. To prevent contamination from expanding, each engine is equipped with its own combined module.
