Every innovation begins with a vision.

Our vision is Minimal ENERGy Application. Since 1980.

To put it simply, we have stirred a great deal of air since 1980. And the aim of achieving the right mixture while doing so has recently been bringing ever more people under Menerga's roof. 

  • Founding year: 1980
  • The marketing of the first energy systems was occured by a few sales-offices
  • Today, more than 400 employees are active for Menerga  - in three company locations in Mülheim an der Ruhr as well as in an European-wide marketing and service


Menerga company was founded. Market launch of the unit series ThermoCond (intelligent swimming pool technology) and AquaCond (heat recovery from waste water)

Market launch of the automatic heat exchanger cleaning system for the AquaCond unit series

Market launch of the Resolair unit series, regenerative heat recovery with over 90% coefficient of performance (COP)

Market launch of the Drysolair unit series (energy-saving air drying)

Replacement of the recuperative aluminium heat exchanger with plastic heat exchangers developed in-house

Market launch of the Dosolair unit series (two-stage recuperative energy recovery) and the Adsolair unit series (cooling without power by means of adiabatic evaporative cooling)

Market launch of the Trisolair unit series (three-stage recuperative energy recovery)
