China Custom Auto Switch Water Cooled Screw 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.
Jiangsu Huazhao Refrigeration Equipment CO., Ltd. is a manufacturing enterprise focus on high quality industrial refrigeration equipment research and development, production and sales.
Our company various industrial chiller with competitive price include: Air cooled chiller; Water cooled chiller; Low temperature glycol/brine water cooled chiller; Heat pump hot water chiller; Maglev inverter centrifugal water chiller; Oxidation dedicated water cooled chiller.
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
