1 x GK 140 for Compressed air and heat generation

Gas engine compressor unit GK 140 in Oberndorf

In southern Germany’s metal-processing H&K plant the first gas engine compressor unit (GK-unit) developed by SOKRATHERM and our technology partner BOGE started operation in December 2022. At full load the unit type GK 140 generates 23.3 m³ compressed air per minute with 8 bar pressure and additionally 309 kW heat. Due to the smart utilization of every heat source its thermal efficiency of roughly 90 % is in the range of conventional boilers.

The article Druckluft-KWK für die Industrie („Compressed air cogeneration for the industry“) about the project and the compressed air generation with our new GK series has been published in the stadt+werk magazine. During the article publication in November 2023 this GK 140 unit had run for over 5000 operating hours and proven the reliability and efficiency of the system. In a few month another GK unit will be commissioned.
