Compression refrigeration directly from your waste heat - unique worldwide!

Cold - DeVeTec GmbH

Our cooling-producing heating power station

Do you have production processes that generate waste heat and also require compression refrigeration?

We offer you the possibility to generate the required compression refrigeration with your waste heat - environmentally friendly and economical!

Here are just two examples of industries where sensible waste heat utilisation is beneficial:

  • Food production: It is possible to use waste heat from baking ovens to generate cooling for your cold stores by means of our DeVeTec heating power station.
  • Chemical industry: The energy to be dissipated from exothermic processes can be harnessed for cooling process streams.

Production of compression refrigeration without the use of fossil fuels and without intermediate electricity production

Thanks to the DeVeTec technology, there is the unique possibility of driving the refrigeration compressor directly with the piston expander of the heating power station. The comparison with other methods of cooling production makes the advantages clear:

 Three different sizes are available for cooling production. If larger amounts of heat are available, a combination of several heating power stations - also with different purposes - is possible:

Each of our heating power stations is equipped with the exact refrigeration compressor that will allow the cooling to be used at your site:

  • The cooling temperatures are selected so that the heating power station produces the required cooling.
  • The auxiliary equipment of the compression refrigeration system is part of our cooling-producing heating power station.
  • It is possible to use the heat from the compressor cooling


Every waste heating power station reduces your CO2 emissions:

  • Displacing conventionally electric-powered cooling reduces the amount of electricity drawn from the transmission grid. The CO2 emissions associated with electricity production can thus be avoided.
  • The use of the useful heat from the waste heating power station leads to a reduction in the purchase of fossil fuels, such as natural gas or fuel oil, and thus to a reduction in the emissions generated during combustion.
