2 Features
1). Low ambient temperature cooling function
the ambient temperature is down to -10 ℃in cooling mode with low ambient kit，this function should be
activated by S8 switch on the PCB board.

2). Wide range of outlet water temperature
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 water system.
Heating: 40~50˚C (Set in factory), 22~50˚C can be available by switch the address.

3).Digital scroll technique
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. Digital scroll technique, provide maximum reliability,
high efficiency and quiet operation.
4).Modular design, flexible combination
The unit adopts modular design, which can make more units to connect together. The unit can be combined
max16 modules (30&65kW module),5 modules (200kW module) or 8 modules (130&250kW
module),meanwhile every separate module can be operated as main unit, also each module can be a slave
unit with modules combination(The digital unit must be operated as main unit if the system has digital unit.),
more convenient for design and installation.
5).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.

6). Backup functions
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 happens, this unit will stop but the others will keep running.
If slave unit’s protection happens, this unit will stop but the others will keep running.
( Except PE, P9 protection happens)
PE：Low temperature protection of evaporator.
P9：Outlet and inlet water temperature difference protection.
7).Built-in hydraulic module (Available for MGCSL-F(D)30W/RN1)
The unit built-in hydraulic module to simplified installation, save space and
outstanding appearance, simultaneous effectively reduce installation costs and
covering area.
8) 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.

9).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.
Note: When use the remote control function, the wired controller will be invalid.
10). Easy transportation and installation
Air cooled scroll chiller structure is compact, light weight, easy transportation and installation, no need
cooling water tower, significant cost-savings.
Easy to transport No need cooling water tower
11). Reliable protections
Many kinds of protection are adopted to make sure the safe running for chiller.
12). Super reliability
System will be more reliable with new type efficient heat exchanger.
Evaporator of 30kW module adopt double-pipe heat exchanger，evaporator of 65kW ,130kW,200kW and
250kW modules adopt shell and tube heat exchanger.
