Combined Heat and Power

YANMAR’s Combined Heat and Power (CHP) system uses an internal combustion engine, powered by clean natural gas, to produce both heat and electric power. Save on bills and protect the environment!


Variable Refrigerant Flow

Using a natural gas-powered engine to drive dual scroll compressors, YANMAR’s Variable Refrigerant Flow (VRF) Heat Pump maintains heating performance by capturing heat off the unit’s engine to increase efficiency.
