The management

Dr. Jürgen Süß has been the managing director of Efficient Energy GmbH since 2013. An expert in the field, he relies on his congenial character to inspire and motivate the team of technicians, engineers and specialists.

The inventor

Water (R718) as a coolant – in the beginning it was just a vision of Holger Sedlak, who soon found a comrade-in-arms in Oliver Kniffler. With ingenious approaches, persistence and the right partners and experts on board, they developed nearly all required components themselves, since they were not available on the market. After 8 years of development, eChiller was presented to the general public for the first time at the Chillventa 2014.


From research project to future-forging enterprise

Thanks to its first rate, exceptionally qualified staff and know-how, efficient energy has become a strong, competitive enterprise with an unrivaled product: eChiller®.
