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.
