Compact CHP ready for connection, mainly
Integrated heat exchanger basket, mainly
consisting of
consisting of
- serially manufactured Industrial-Gas-Otto-engine
- air-cooled synchronous generator
- expansion tank in motor circuit
- relief valve in motor circuit and heater circuit
- exhaust heat exchanger integrated in primary
- filling valves, cleanout valves and exhaust valves
- plate heat exchanger
cooling circuit
- 3-Way catalyst integrated in exhaust heat exchanger
- oil reservoir with automatic oil refilling
- pumps for motor circuit and heater circuit
- 3-way mixing valve for return temperature increase
- control cabinet with programmable controller and
operating unit
- gas train
Water and gas connections are executed with compensators. All water-side connections are directed upwards
above the heat exchanger basket.
Motor and generator are connected through a pluggable elastic metal-plastics coupler to compensate radial offset,
axial offset or angular offset. It is mounted on a framework vibration-reduction.
Furthermore the framework is uncoupled through oscillation decoupling elements.
The control cabinet is executed as a separate unit. All regulation and control functions as well as control elements are
part of the control cabinet. Assisted by a menu-navigated touch-screen performance data and state data can be
read and adjusted easily.
The drive of the CHP is caused by a water-cooled Otto-Gas-Engine. It is a stationary engine designed
for permanent operation. A microprocessor-controlled ignition ensures an optimal adaption of the ignition point and the
ignition energy to the gas quality (methane number).
The oil level control is carried out by a sight glass with oil level deficit indication, which is connected with the oil pan.
