The new gas engine compressor module from SOKRATHERM produces compressed air and industrial heat in a gas-fired combustion engine at the same time, achieved by connecting it with BOGE's S-4 series screw compressor.
SOKRATHERM and BOGE have proven that a heat and power plant and a screw compressor can be connected, jointly developing a series of compact and efficient gas engine compressor modules.
SOKRATHERM sales manager Joachim Voigt said the company made a technical distinction when developing the compressed air combined heat and power station.
“BOGE contributed its expertise in the area of compressor technology and we our expertise in the field of CHP. The partnership was a perfect symbiosis, because each side benefitted from the specialist knowledge of the other,” said Voigt.
The collaboration began with a specific project enquiry in 2019. One year later, SOKRATHERM won the order, and by March 2021 the unit had already been completed and delivered.
Tried and tested technology from both companies was used, resulting in a reliable system for the 50 to 200 kW mechanical power range. The new GC product range was based on the existing range of natural gas powered CHP compact modules.
Economic efficiency, small footprint
The usual running costs for generating the compressed are obviated when operating the compressor. With a thermal efficiency of almost 90 per cent, and the extra compressed air production, the GC modules have paid for themselves within two to three years if the unit is used to cover the relevant base load for heat and compressed air.
The footprint of the compact system requires a relatively small installation area. Heat exchanger, oil circuit and other components are integrated in a separate module which offers flexible positioning options.
SOKRATHERM can now provide a broad portfolio of units at varying performance levels. The modules are flexible and can adjust to different requirements, and the integrated gears of the screw compressor allow perfect coordination between the gas engine and compressor; free air delivery and pressure can be controlled individually.
