1，Multi safety protective system; safe running and good reliability;
Use world famous brands parts, abide by advanced design principle, in the making of safe and sound system. The system has comprehensive protection against high pressure, low pressure, oil volume monitor, oil temp.control, oil level control, motor overload control, overheating etc.
2，High efficiency, energy-saving
Original imported screw rod compressor, in low temperature working conditions, the refrigeration capability can be increased by over 35%, refrigeration efficiency increased by over 20%, it can be PLC automatic controlled when form parallel units. Compared with normal machine, it can save electricity by 20-50% in different occasions.
3，less space occupation and easy installation
Before delivery, the major refrigeration system and electric system have been tested and on customer site, they can be in operation after simple work. The units structure is compact and well designed, occupy less space which is only 1/6 of the ammonia machine room.
4，advanced PLC control that can realize remote control
The controller can realize remote control of the units, all equipment`s running in all cold rooms can be controlled and monitored in office or control room.
5，Graded power control which lead to energy-saving
According to temperature requirements, through pressure sensor to detect the system pressure and automatically control the opening and closing of several compressors, the system can be ensured in the most economical and best working conditions thus saving the running cost at most. Parallel units can decide the quantity of machines to be opened and running time due to different heat load of cold rooms. When large cold volume is needed, multiple machines are kept in work; when small cold volume is needed, single machine runs which consumes less power. Even if some machine is broke down, it will not influence other machines and this ensures system safety and stability.
Connected multi compressors in parallet,share discharge and suction pipe,condenser and liquid receiver,for bigger capacity condensing system and easy conrtol.
.Greatly reduce the failure to complete system,to improve the reliability.
