2. Features
1). Wide range of outlet water temperature
Cooling: 5~17˚C (7˚C is default, set in factory), 0~17˚C can be available by switch the S5 on PCB, the
antifreeze must be put into pipeline.
Heating: 40~50˚C (45˚C is default, set in factory), 22~50˚C can be available by switch the address.

2).Humanized remote control
S7 address on PCB should be switched to ON to realize remote
control, which including remote ON/OFF, remote heating and
cooling mode selection, remote alarm. The customer can simply
and conveniently control the chiller and acquire the running
information on real time in door.
3).Modular design, flexible combination, more convenient for design and installation.
The unit adopts modular design, which can make more units to connect together. The units can be
combined freely, meanwhile every separate module can be operated as main unit, also each module can be
a slave unit with modules combination, more convenient for design and installation.
4).The maximum combination of the system consists of 1 main unit and 15 slave units for
30kW&60kW modules, 1 main unit and 7 slave units for 120kW module, 1 main unit and 4 slave units
for 180kW module.
Easy connection between main unit and slave units.
All the units can be connected together with a wired controller in series type. Using three-core shielded
twisted wire as communication wire.

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.
