custom Flooded Type Screw Type Chiller,Flooded Type Screw Type Chiller exporter

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. Min.outlet temperature can be -60℃.

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.
