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

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.
