Multi Zone Inverter Heat Pump
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
consistent by eliminating the harsh starts & stops of conventional systems. Each outdoor coil has
a corrosion resistant acrylic resin coating to maintain energy efficiency.
Features and Benefits:
High Efficiency up to 22 SEER
Sound Levels down to 56 dB(A)
Up to 5 indoor units
