5).Environmental care
R410a
— the environmental refrigerant.

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, the adjustment can be made fast linear
response, making the system more stable output, the indoor temp. more uniform, and enhanced human
comfortable.
7). Compact structure
The structure of air-cooled modular chiller is compact, light weight. The system adopts double-pipe or shell
and tube heat exchanger, which not only greatly enhanced the transfer performance, but also reduced the
unit weight, the lightest single module has only 380kg.
8). 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
