Capacity : 40 - 400 USRT
Unit Features :
High efficiency and low noise domestic double screw compressor
The use of high efficiency mesh copper pipes with liquid pipe operation room for future maintenance and repair
3. Water cooler
Adopt high efficiency internally threaded cooper tube, dry heat exchanger, and the outer layer is covered with 3/4" thick PE foam insulation
Imported external pressure equalizing thermal expansion reading
5. Distribution box
The unit includes power distribution for control, including Y delta starters and phase-switching related electrical appliances required for machine control function
Refrigerant liquid pipe line filter, refrigerant high pressure meter, low pressure meter
7. Protective device
There are protection for high pressure which too high, low pressure which too low, outlet water temperature function which too low, compressor motor overload protection, compressor motor coil overheat protection, main power reverse phase protection, pre-flow water flow switch chain protection contact
The standard unit performs insulation work in the factory and fills the refrigerant required by the unit before performing various protection. After the device is tested and the unit is in operation, and after the quality control inspection is passed, the unit is ready shipped out
Low noise and high efficiency
The compressor adopts the most advanced 5 to 6 asymmetrical toothed twin screw rotor, which has smooth operation, low vibration and low noise, high efficiency and other advantage
Multi-stage volume control, free adjustment of refrigeration lad changes
The compressor has a 25%-50%-75%-100% four-stage volume control system, the main unit has a low starting current, and is suitable for changing the freezing load condition, the energy saving function can be achieved.
Fewer parts and simple maintenance
The screw compressor has fewer parts fewer failure points, and the motor and the body are of separate design, easy to repair and maintain.
Safety protection device
The unit is equipped with multiple protection such as high and low voltage switches, antifreeze switches, fusible plugs, overload protection devices, line country overheat protectors. reverse phrase protectors, and other multiple protection device.
