Semi closed Screw Type Chiller,Flooded Type Screw Type Chiller factory
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℃.
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
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.
