Product Brochure

High Efficiency Multi 21 heat pump units can heat and cool up to 5 zones without distribution boxes.
Each Multi 21 is powered by Gree’s energy efficient G10 inverter and a variable speed compressor.
Our G10 inverter technology saves energy, reduces outdoor noise and keeps room temperature
steady by eliminating the harsh starts & stops of conventional systems. Each outdoor coil has
a corrosion resistant Gold Fin coating to promote energy efficiency and prevent coil corrosion
incorrosive environment.
