E²CON-GE: The Jenbacher Retrofit for more
flexibility and an independent gas engine

Increasing the efficiency of gas engines in the context of modernization and new cogeneration plant operating concepts demand stable and performance-enhancing components as well as a more open and flexible gas engine control system. One that can keep the engine operating safely at the limit of its mechanical repowered parts while at the same time integrating it seamlessly into the cogeneration plant or into a whole network of plants.

With the Jenbacher engine specialized control system, system upgrades are straightforward while providing more options for your individual specifications.

The tailor-made engine controller for Jenbacher gas engines is a specialized control system which is open for all types of expansion. Functions, modules and subsystems harmonize with a high performance user interface to form a single unit. The application for Jenbacher engines covers all your known requirements.

A reliable and flexible solution

The flexible and open Engine Control System is based on openECS by AVAT and on classic PLC components. A wide range of interfaces make them an ideal control center for integrating all types of components. To control gas engines in cogeneration plants, sensors and actuators are needed that cannot be connected to a classic PLC. This is where the AVAT technology software and hardware modules, e. g. against knocking and misfire, came into use. Further information about the openECS principle here.
