GREE Air-ccoled Closed Control Unit Service Manual
4
Rapid dry: the evaporator has two-stage. In dry mode, by reducing heat exchange area of
evaporator and evaporating temperature, the unit can rapidly dry and precisely control ambient
temperature and humidity.
◆
Modular Design
High Precision: High precision: each module can be individually controlled. The cooling
capacity can also be individually controlled to flexibly adapt to environment and decrease
fluctuation of temperature and humidity.
Alternate operation: According to accumulated operation time, the unit which has less
operation time will start operation firstly while the unit which has more operation time will stop
firstly. Each module can alternately operate and be evenly controlled. If any module has
malfunction, others will automatically operate.
Convenient expanding of capacity: max. 253 master modules can be connected so the
problem of increasing heat load of the room can be flexibly handled and cost of further capacity
expanding by customer can be reduced.
Flexible installation: Single module can be casually installed according to layout of the
room, which makes the humidity and temperature of the room more even.
Convenient transportation: the single module is separately packaged so transportation and
installation are more convenient.

Structure Features
Separate electric control: electric control cabinet is totally separate with cold air circulation
system so there is no incipient fault caused by condensate and short circuit.
Convenient disassembly: main front panel Assy is fixed by clasp so the disassembly is very
convenient and the appearance is also nice.
High efficient filtering: There is G4 grade wide air filter in air return inlet of indoor unit to
guarantee cleanness and reduce loss of air pressure.
Snow-proof design: for outdoor unit, the air returned from the bottom and supplied from the
top to prevent the vent from being blocked by snow.

Multi products
Wide cooling range: GREE JKF series air-cooled closed control units include 5kW, 7kW,
15kW, 20kW, 25kW and 40kW units. And also, with combination of modules, customers can
easily select proper units according to their demand.
Various air outlet ways: Each kind of unit has three ways of air outlet, including free air
outlet (with cap), front air inlet and top air outlet (connecting to duct type), top air inlet and
bottom air outlet (air supplied from floor). Customers can freely select the units according to
specific conditions.
