1.4Products characteristic

(2).HFC refrigerant technology

To protect the environment, we have adopted the HFC refrigerant. The HFC R407C is of zero ODP

for the purpose of environmental protection.

(3).Ceiling/console convertible,flexible installation,convenient maintenance,saving

the users' expenditures

(4).Adopting single-phase or three-phase power supply,applicable for household

and commercial usage

(5).Dual air outlet design,floor air blowing,accelerating the indoor air circulation,

quick temperature adjustment

(6).Long-distance air blowing,large power,large cooling/heating ratio

(7).Intelligent remote control,convenient and flexible control

(8).Super-slim indoor unit design,luxury and nice-looking,saving space,harmonious

and unitive with the indoor environment

(9).Adopting screw-fastening for the air inlet grill,firmly fixed;adopting slipway

insert-lock fastening method for the filter screen,convenient cleaning or replacing

the filter screen without opening the air inlet grill.

The system can run the cooling operation at the low ambient temperature -15

(1).Low ambient temperature cooling technology

(10).Group control,units up to 128 sets can be controlled
