2. Features of Product
Gree JKF Series Air-cooled Closed Control Unit is specially designed for the room where
communication equipment, computer, and precise instruments are placed. Applying
components with high performance, wide and touchable screen, advanced system design as
well as powerful control logic, the unit can efficiently control ambient humidity and keep stable
and long-term operation. The unit has been thoroughly tested with high standard and has been
under strict production control. All units have reserved remote monitoring function. Cooling
capacity of a single unit is between 5kW
～
40kW and can be expanded by combination of
modules.
◆
Powerful control function
Touchable screen control: with 7’ touch screen to achieve easy, swift and convenient
control and operation.
All-sided monitoring: inspect the operation of the unit in all sides, including ambient temp
and humidity, temperature of evaporator, status of each component of the unit. (such as indoor
or outdoor fan, compressor, electric heater, etc), voltage, current, etc)
Multi functions display: use value, phrases, and curves to display data regarding operation
of the unit or environmental phenomenon.
Human-friendly control: each parameter or warning can be set according to the demand of
user. If malfunction occurs, the unit will give warning and, at the same time, it will keep running
or stop, which is selected according to the type of the malfunction.

◆
High performance and high reliability
High performance: using brandname scroll compressor, female screw thread copper pipe,
Hyrophilic film aluminum fin, condensate fan with stepless regulation, the unit can reach high
efficiency and be energy-saving.
High reliability: All components are brandname products and be inspected by IQC of Gree.
The unit is strictly tested and can stably operate for long-term.
Operation under ultra low temperature: the unit can reliably operate even though outdoor
temperature is -35
℃
. The room temperature and humidity can be stable under all kinds of
rough conditions.
High sensible heat: it is designed for work condition with high sensible heat and can reduce
repeated humidifying as well as avoid condensate.
Huge air volume: use high efficient centrifugal fan which produces huge circulated air
volume to rapidly make temperature and humidity in the room even and clear local heat
generation.
