1.4 Features
1). Wide range of outlet water temp. (For MGBT-D60W/RN1, MGBT-F250W/RN1)
Cooling: 5~17˚C (7˚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 (45˚C set in factory), 22~50˚C can be available by switch the address.

2).Humanization remote control (For MGBT-D60W/RN1, MGBT-F250W/RN1)
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 module and acquire the running
information on real time in door.
3).Digital scroll technique，new type air-cooled modular 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% after modules combined, 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.
4). Easy and fast installation
The unit adopts modular design, which can make more units connect together. The unit can combine 16
separate module(equal and less than 65kW) or 8 module(250kW).Cooling(heating) capacity can increase
step by step by 5KW per each time within 15kW-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.
The maximum combination of the system consists of 1 main unit and 15 slave units for 25kW&30kW&60kW
module，1 main unit and 7 slave units for 120kW module, 1 main unit and 4 slave units for 180kW module, 1
main unit and 7 slave units for 250kW module.

Easily connect 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.

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)

9).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.
10). Superior reliability
System will be more reliable with new type efficient heat exchanger.
Evaporator of 25KW and 30KW module adopt double pipe heat exchanger，evaporator of 60kW ,120kW and
180kW modules adopt shell and tube heat exchanger.
