1). Low ambient temperature cooling function (Available for MCC(D)H30A-TA3SL,
MCC(D)H65A-SA3L, MCCH130A-SA3L)
The ambient temperature is down to -10℃ in cooling mode, and heating down to -10˚C ambient by added
one board (see picture1). Wide ambient temperature range are available by adjustable address between
different conditions to meet different requirements.

Cooling: 5~17˚C (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 (Set in factory), 22~50˚C can be available by switch the address.

3).Built-in hydraulic module (Available for MCC(D)H30A-TA3SL)
The unit built-in hydraulic module to simplified installation, save space and beautification appearance,
simultaneous effectively reduce installation costs and covering area.

4).Humanized remote control (For the module with KJR-120A/MBE)
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.
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 output 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 be combined
max. 16 separate module(30, 65kW module) or 8 module (250kW module).Cooling(heating)
capacity can be increased step by step by 5kW per each time within 30kW-2000kW,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.
7).The maximum combination of the system consists of 1 main unit and 15 slave units for
65kW module, 1 main unit and 7 slave units for 130kW module, 1 main unit and 4
slave units
for 185kW 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 double pipe, 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.
11).Backup function
When unit is failed.
 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)
PE： Low temperature protection of evaporator.
P9： Outlet and inlet water temperature difference protection.

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.
Evaporator 30kW module adopts double pipe heat exchanger ，evaporator of
65kW ,130kW, 185kW and 250kW modules adopt shell and tube heat exchanger.

Note:
Please refer to the water flow volume in the above table strictly to design and install.
All the above data is measured base on the following working condition:
1. Cooling mode: water side fouling factor: 0.086m2·℃ /kW, chilled water inlet/outlet: 12℃ / 7℃, and outdoor ambient temp. of
35℃ DB.
2. Heating mode: water side fouling factor: 0.086m2·℃/kW, warm water inlet/outlet: 40℃ / 45℃, and outdoor ambient temp.
7℃ DB/6℃ WB.
