4).Humanization remote control (For MGCSL-F(D)30W/RN1 ,MGB-D65W/RN1, MGB-F250W/RN1)
S7 address on PCB should be switched to ON to realize remote
control, here are reliable: Remote ON/OFF, remote heating and
cooling mode selection, remote alarm. The customer can simply
and conveniently control the module and acquire the running
information on real time in door.
5)Digital scroll technique，new type modular air-cooled chiller
system.
Capacity output is controlled depending on controlling compressor to on/off in traditional modular air-cooled
chiller system control. The precision of the control mode is not very good, and the compressor is frequently
on and off, which is very bad for the compressor’s life.
Digital scroll modular air-cooled chiller system breaks traditional design, which is inconceivably designed
with digital scroll compressor and constant scroll compressor parallel connection. the system can achieve
linear capacity adjustment within 0.5%-100%,the scope is widest in industry. When the system operates at
the part-load, the system can accurately adjust cooling and heating capacity output basing on actual
requirement of the indoor room.
6).Modular design, flexible combination, more convenient for design and installation.
The unit adopt modular design, which can makes more unit connect together. The unit can combine 16
separate module(25,30.55.60.65KW module) or 8 module(250KW module).Cooling(heating) capacity can
increase step by step by 5KW per each time within 25kW-2000kW,meanwhile every separate module can
operate as main unit, also each module can be a slave unit with modules combination, more convenient for
design and installation.
Max 8 modules
250KW
250KW
2000KW
7).The maximum combination of the system consists of 1 main unit and 15 slave units for
25,30.55.60 and 65KW module, 1 main unit and 7 slave units for 130KW module, 1 main unit and 4
slave units for 200KW module，1 main unit and 7 slave units for 250KW 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.

8).Environmental care
Ecological R410A 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.
9) 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.
10).Compact structure
Air cooled modular chiller structure are compact, light weight. The system adopts tube in tube, shell and tube
heat exchanger, not only greatly enhanced the transfer performance, but also reduce the unit weight, the
lightest single module only has 380kg.
The characteristic of unit decided cooling tower is not needed, not only reduced installation costs, but also
resolved the cooling tower generated noise when running.
11).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

12).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.
13). Superior reliability
System will be more reliable with new type efficient heat exchanger.
