Semi closed Screw Type Chiller

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. Min.outlet temperature can be -60℃.
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. The unit adopts a 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.
2. The unit heat exchanger adopts high-efficiency heat exchange tube to improve
the cooling efficiency. At the same time, in order to reduce the lubricating
oil entering the heat exchanger, the unit increases the secondary oil content,
minimizes the amount of oil entering the heat exchanger, and passes the
specially designed ejector. The oil return device directs the lubricating oil
in the heat exchanger back to the compressor to improve the refrigeration
efficiency of the unit and also improve the reliability of the unit operation.
3. The unit is equipped with multiple protections to make the unit operate
safely and reliably. The unit adopts direct cooling mode, which reduces the
loss caused by the intermediate heat exchange and greatly reduces the running
cost.
4. Environmentally friendly 134a refrigerant is used to improve unit operating
efficiency. The unit is equipped with multiple protections to make the unit
safe and reliable.
