E²CON-CHP: complete control system
for all kind of engines and CHP modules

The further development of gas engines and new cogeneration plant operating concepts demand a flexible engine controller. One that can keep the engine operating safely at the limit of its mechanical performance while at the same time integrating it seamlessly into the cogeneration plant or into a whole network of plants.

Based on the open and flexible openECS hardware and software components, the E²CON-CHP creates a control system for the entire CHP modules including the gas engine. For typical applications we already have tried-and-tested configurations - from circuit drawings to system visualization. The ideal starting point for coming to your new and scalable solution with minimal adjustments. Further information about the openECS principle here.
