Combined Heat and Power

R-Gen Gas CHP

The Remeha R-Gen Combined Heat and Power (CHP) range is the sustainable solution to providing highly efficient heat and power for applications with consistent heating and electricity. Converting gas into both electricity and heat in a single process at the point of use, the R-GEN NG operates at a higher level than traditional generation. It delivers a primary energy saving of up to 30% and up to 20% reduction in emissions. The R-Gen 20/44 NG and 50/100 NG models can achieve outstanding total-fuel efficiencies of 103-104%, reducing greenhouse gas emissions by up to 60% and primary energy consumption by up to 40%.
