Semi closed Screw Type Chiller
Water Cooled Screw Chiller
Description:
The series water chiller adopts efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient. The unit heat exchanger adopts high-efficiency heat exchange tube to improve the refrigeration efficiency, and the unit is equipped with multiple protections to make the unit operate safely and reliably.
Features of chiller:
Safety system:
1 Compressor reverse protective
2 Freeze protector protective
3 Refrigerant safety valve
4 Buzzer
5 High-pressure gauge and Low-pressure gauge
6 Power phase failure protector
7 Coil over-heat protector
8 Temperature auto-switch
9 Refrigerant shortage protective
