• Offer Profile
  • Our Company. Your Partner.

    We are an Austrian company that manufactures biomass energy systems for the international market. With our work we bear an economic, environmental and social responsibility for present and future generations.

    Biomass plants with IQ: Listen, observe, understand

    The many years of practical experience of plant operators in the daily interaction with energy from biomass is a constant element of KOHLBACH's continued development. We also carry out regular test runs for our customers and then immediately incorporate the results into the system concept. A KOHLBACH plant is always "state of the art", which is why we put our name on it.

     

Product Portfolio
  • Combustion systems

  • The combustion systems are individually adapted to the fuel and provide an optimal combustion of the biomass material.

    We have the suitable furnace solution for the biomass fuel of the customer: sawdust, bark, wood chips, landscaping residues, nawaro wood, very wet or dry fuels with very high ash content, rough and inhomogeneous fuels or fine fuels, admixture of selected agrarian fuels — your solution is our combustion systems.
