Complete control system
for CHP engines and modules

E²CON-CHP

[Translate to English:] AVAT BHKW Standard Application

The flexible system for engine,
generator and all auxiliary units

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 our flexiblehardware 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.

With our modular principle, you implement the control for engine, generator and auxiliary units up to central SCADA systems with just one concept. Ultimately, you decide what we deliver: The standard application or a solution ready adapted to your requirements, on which our or your developers can continue to work.

Certification: For the use of E²CON-CHP according to VDE-AR-N 4110 (TCR Medium Voltage) Code of Practice, a certificate is available. Request our list of certified combinations of gas engines, generators and electronic components already certified with E²CON-CHP. If our already certified modules do not cover your requirements, our modular TCR certificate at a fixed price will help you – contact us now!

The "Technical Connection Rules Medium Voltage" VDE-AR-N 4110 (TCR Medium Voltage) Code of Practice, defines the requirements for energy systems at this voltage level. Manufacturers have to comply these technically binding standards in Europe in order to enhace the energy plants and grids in the long term.
