BIOGAS AND OTHER GASES 

Economical. Sustainable. Clean.

Today and in the future, our focus is on developing and implementing system solutions for producing energy from climate-neutral regenerative fuels: such as combined heat and power systems (CHP) for biogas.

The principle of a CHP system based on biogas is simple: biogas is generated during fermentation of organic material and collected. It is then used by a cogeneration system to create heat and power to be used locally or fed into the national power grid (as provided for by the Renewable Energy Act in Germany). The generated heat can be used during fermentation processes or to heat commercial buildings or residential areas.  

Our biogas powered CHP systems represent the ideal solution for multiple applications:

  • Agricultural farms
  • Sewage and water treatment
  • Landfills

Electrical power range: 175 – 400 kWe

Minimum space. Maximum efficiency.

Features of the extended Series 400:

  • Flexible scope of supply: All systems are available in open or soundproofed designs, either for building into existing facilities or as turnkey systems.
  • Modular design: The generator set can be configured to your specific requirements. All modules are designed to work together in perfect harmony.
  • Standard interfaces and components enable our systems to be installed quickly and maintained easily.
  • Unceasing design improvement and development work for over 35 years
  • Best overall efficiency in this power range (up to 91.9%)
