The company specializes in creating pure space environments for clean room applications such as hospital operating theaters, laboratories, pharmaceutical facilities and micro-electronic assembly areas.

Ener-G already owns Hungarian cogeneration company EnerR-G Energia Technologia, which was acquired in 2006, and the enlarged group is expected to benefit from synergies between the two Hungarian enterprises.

The acquisition of Klima Controll brings Ener-G’s major transactions to four in 10 months, following its purchase in October 2007 of utilities services company CMR Consultants; energy metering and control business Switch2 in December 2007; and renewable, geothermal heating and cooling specialists Ground Source Solutions in April 2008.

Klima Controll was acquired from the family of Imre Koszta, who will continue to run the business together with Zoltan Ballago as project manager and Zsolt Racz as service manager. Ener-G group managing director Derek Duffill, together with Peter Szabo and Balazs Marialigeti of Ener-G Energia Technologia, will join the Klima Controll board.
