
Chlorine-free and environmental friendly refrigerant, zero ozone depletion potential.

High-density refrigerant, therefore, less refrigerant required.

Leak-tight refrigerant circuit, Brazed refrigerant connections for increased leak-tightness.
6) Economical operation
New design adopts electronic expansion valve precise refrigerant control in wider range. Electronic
expansion valve allows operation at lower condensing pressure, adjustment can be made fast linear
response, making the system more stable output, the indoor temperature more uniform, and enhance
human comfortable.
7).Back up function
When unit is failure

If master unit fails, all the units will stop.

If one slave unit fails, this unit will stop but the others will
keep running.

When the master unit fails, any of the slave one can be set
as the master unit by manual setting.
When unit is under protection
 If master unit’s protection occurs, this unit will stop but the
others will keep running.
 If slave unit’s protection occurs, this unit will stop but the
others will keep running.

( Except PE, P9
protection happen
)
8).Strong micro-computer intelligent control and monitor function.
Optimizing the design of system and using varieties of protection devices, to make the system more safe
and reliable.
9). Superior reliability
System will be more reliable with new type efficient heat exchanger. The 30kW module adopts double pipe
heat exchanger, the 60&120&180kW module adopt shell and tube heat exchanger for evaporator.
