G-Box 50 - The compact solution for professional applications


The G-box 50 is a module developed by 2G systems to contribute significantly to the reduction of energy costs and to protect the environment. In comparison to uncoupled heat and power production, the 2G innovation can operate with 40 percent less primary energy. CO2 emissions are reduced by up to 60 percent. With an electrical output of 50 kW, the G-box 50 reaches a total efficiency of up to 103 percent (based on the lower heating value of gas and max. 50 ° C return temperature). The heat loss is virtually zero, because the exhaust emissions temperature is cooled to 60 ° C and the generator has its own water cooling system. The module also demonstrates excellence in sound protection: the sound pressure level is consistent with structure-borne sound and guards in a meter's distance a maximum of 52 dB (A).

Typical Applications:


Senior centers and hospitals

Shopping centers

Swimming pools
