SOKRATHERM Stand in Hall 2

From 23-25 May, the E-world energy & water fair will take place in Essen. In hall 2 we will present a newly developed combined heat and power unit (CHP) of the 400 kW class with an output of 357 kW electric and 445 kW thermal power at our stand 2-505.

The heart of the compact CHP unit is an 8-cylinder MAN turbo engine of the latest generation, which can already be operated with 20 % hydrogen (H2) and after a corresponding modification with 100 % H2. In natural gas operation, this CHP unit achieves an electrical efficiency of 40.2 %.

Together with the thermal efficiency of over 50 %, the exhibited CHP type GG 355 has an overall efficiency of 90.3 %, which can be increased by up to 8.8 % with an external condensing heat exchanger. Thus, under optimal operating conditions, an overall efficiency of almost 100 % can be achieved.

Compact CHP unit GG 355 in Oberhof

Our most prominent application example is the Grand Green family hotel in Oberhof, where top athletes from all over the world have competed in the luge and biathlon World Championships in early 2023. The online editions of BWK and Hotel+Technik have, among others, reported on the project. Further projects with this CHP unit type are in Magdeburg, Hamburg and Berlin.

At the fair stand, our sales engineers will be happy to answer questions about this and all other CHP unit types or further developments such as our units for the generation of compressed air and heat or the efficient combination of CHP units with heat pumps.

For free access to the trade fair, you are welcome to request an invitation code from us by e-mail to info|at|

We look forward to your visit!
