GREE Multi 21 systems, with inverter technology, are some of
today’s most advanced ductless split heat pumps. Providing
both cooling and heating comfort, in as many as five separate
zones, they are the perfect solution for many residential and
light commercial applications. Multi 21 systems reduce
energy waste, maximize efficiency and achieve up to 22
SEER, with our G10 inverter driven compressors. Best of all,
the ultimate in reliable room comfort is generated with Ecofriendly R410A refrigerant.
Design Flexibility
Gree introduces project layout flexibility by simultaneously powering up to five indoor units with one outdoor unit. For
even greater flexibility, mix and match your choice of Wall Mount, Ceiling Cassette, Concealed Duct, Universal Floor/
Ceiling and Mini Floor Console indoor units to create your unique Multi 21 heating and cooling system.
Energy Savings
Gree Multi 21 systems are highly efficient zoning heat pumps that will keep operating costs under control, year round.
No need for a bulky add-on coil or expensive-to-operate electric heat. Our variable speed heat pumps, powered by the
G10 inverter, provide the same heating capacity as electric heat, while using as little as 1/3 the electricity. With Multi 21
ductless systems, there are no losses due to leaky ductwork.
Maximum Comfort
Multi 21 systems eliminate irritating temperature swings, by continuously monitoring comfort levels and adjusting
compressor speed and refrigerant flow according to the cooling and heating needs of each room. Additionally, you can
create your own personal-comfort-zone, by activating the I-Feel function on the remote control. With I-Feel activated,
Multi 21 systems will sense temperatures surrounding the remote control, and adjust compressor speed and air flow to
maintain the comfort level of your personal space.
Durability & Longevity
All duct free Multi 21 units are made from heavy gauge rolled steel and covered with a durable powder coat paint finish. Gree’s
enhanced Gold-Fin coating provides condenser coil protection in corrosive environments, while improving hydrophilic
properties and efficiency; and our multi-point self-diagnostics continuously monitor critical system parameters to prevent
catastrophic failures. These, along with many other, design considerations will extend the life of your Multi 21 system.
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
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.
