high quality 50HZ water chiller

China Custom Auto Switch 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:
1. Employing original single/double SCREW compressor, Compressor may according loading auto-adjust, add level sensor for prevent compressor low-loading to luck-oil, extent use life
2. Employing all-new imported high class component
3. Employing two sets of compressor which can be used jointly or independent
4. Switch control, easy operation and maintenance
5. The weld of brass pipe is non-oxidization
6.Condenser and Evaporator both to conform GB150, GB151, TB/T4750-2003,operation safe

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
