Product Brochure

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 heat at up to 1/3 the cost of electric heat. With Multi 21 ductless systems, there are no losses due
to leaky ductwork.
Energy Savings
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. With I-Feel activated,
Multi 21 systems will sense temperatures surrounding the remote control and adj
ust compressor speed and air flow to
maintain the comfort level of your personal space.
Maximum Comfort
All duct free Multi 21 units are made from heavy gauge rolled steel and covered with a durable powder coat paint finish. Gree’s
Acrylic Resin/Anti-Corrosion Coil Protection coating provides enhanced coil protection in corrosive environments, while
improving hydrophilic properties and efficiency; and our multi-point self-diagnostics continuously monitor critical system
parameters to prevent failures. These features, along with many other design considerations, will extend the life of your
Multi 21 system.
Durability & Longevity
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.
Design Flexibility
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 Eco-friendly
R410A refrigerant.
