Product specfication
Refrigerant: R22/R407C
Evaporator max water pressure drop: 1.0Mpa
Evaporator: fouling factor 0.018m2.℃/KW
Power supply: 380V/3P/50Hz
Allowable voltage fluctuate: ±5%
Allowable frequency fluctuate: ±2%
The unit uses high efficiency heat exchanger with advanced, unique shape design and systems. Units can be installed directly on the roof, or other well-ventilated place outdoors, without a separate room, space saving construction. Compact shape, appearance, unit uses “W” type coil design, space utilization, small unit size, in order to adapt to the outdoor weather conditions to ensure that the unit has a good operating results during the life cycle.
Friendy choose to use environmentally R407C, R134A or R410A refrigerant ect.
There may be change of the dimensions without pre notice. For accurate you are welcome to ask us for installing drawing.
