CO2-neutral heat with geothermal energy

As of October 1st, FAHRENHEIT is a member of the “Wärmewende durch Geothermie” initiative, in English: The “heat recovery through geothermal energy” initiative. The initiative works to promote using geothermal energy, the fastest possible solution for supplying urban regions with CO2-neutral heat.

Many of FAHRENHEIT’s installations occur in combination with local or district heating networks. When they are combined with geothermal energy, it is particularly advantageous for the environment. Geothermal energy decarbonizes existing heating networks and reduces energy imports.

Two examples:

In 2015, FAHRENHEIT set up DJE Kapital AG’s head office with a highly efficient adsorption cooling system on behalf of IEP Pullach, the geothermal energy provider in Pullach. The realizable environmental benefits as well as the easily calculable cooling costs, without capital commitment or maintenance costs, were a major selling point. In 2019/2020, DJE Kapital AG expanded their headquarters and a newer version of FAHRENHEIT’s adsorption technology was selected for the new building.

In 2014, FAHRENHEIT worked with the Bavarian geothermal plant operator Geovol to install a FAHRENHEIT adsorption refrigeration plant at their new energy centre. This refrigeration plant operated with district heating of approximately 90°C. With FAHRENHEIT’s adsorption refrigeration technology, Geovol reduced electrical energy consumption by around 31 MWh/y and, according to projections, also reduced CO2 emissions by around 12 tonnes per year.

Save the date! – DENEFF Symposium for Energy Efficient Networks, 04.11.2020

At FAHRENHEIT, we are committed to using energy efficiently and our technology embodies this commitment: our sustainable cooling systems use converted, unused heat and can reduce electricity consumption used for cooling by up to 80%.

That’s why we are proud members of the German Industry Initiative for Energy Efficiency (DENEFF), an independent, cross-industry network of pioneering companies and organizations, working towards effective energy efficiency policy.

At the DENEFF’s upcoming symposium for energy efficient networks on the 4th of November, FAHRENHEIT’s Managing Director, Axel Banoth, will give a talk (in German) on adsorption cooling technology for industrial plants targeted at energy technology consultants and managers as well as network providers and propagators of energy efficiency and climate protection networks. Join us to learn more about energy efficiency and adsorption technology.

The event is sponsored by the DENEFF and the Arbeitsgemeinschaft Energieeffizienz-Netzwerke Deutschland (AGEEN) and is free of charge. To register for the event, please send an e-mail to and indicate whether you would like to participate in Frankfurt or online.

Axel Banoth’s talk starts at 15:30.

Symposium for Energy Efficient Networks – (Hybrid)
Topics of interest for energy efficiency network teams and energy managers in the industry
November 4th, 2020, 13:30 until 17:00
Evangelische Akademie Frankfurt and online

Here is the program.

Save the date! – Swisspower Praxisforum Wärme, 22.10.2020

Have excess heat? Why not use it for cooling instead?

FAHRENHEIT’s Managing Director, Axel Banoth, and Head of Sales, Gregor Feig, will be giving a talk on adsorption chillers at the Swisspower Praxisforum Wärme on the 22nd of October. Interested in how to use heat for cooling? Join us to learn more about how the sustainable technology works, and explore efficient fields of application and practical examples.

Members of the Swisspower Praxisforen will be invited separately. To register as an external guest, send an email to
