Product Description

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.

Application areas:

Widely used in the process cooling of petrochemical, machinery, pharmaceutical, electronics, chemical and pharmaceutical intermediates. Cooling of the plating solution, hydraulic oil and machine tool coolant.

Features:

1. It adopts imported high-efficiency economizer semi-closed twin-screw compressor with high energy efficiency, reliable operation and long service life.

2. Adopt microcomputer controller, touch screen display, the screen can display the unit running status at any time, and can be displayed in two ways of graphical and text table parameters, at a glance. At the same time, it has a fault inquiry function, which is convenient for maintenance inspection.

3. Multiple protection functions: compressor exhaust over temperature, motor over temperature, cold water antifreeze and other temperature protection; over current, phase loss, reverse equal electrical protection; refrigerant system high and low pressure, oil level, water and other state protection.

4. Select the thermal expansion valve, solenoid valve, check valve and other control components of international famous brands to ensure efficient and reliable operation of the unit within a wide range of working conditions.

5. After the machine has passed the comprehensive inspection and the full-load operation test, it will be shipped with the refrigerant to ensure that the equipment can work after the water and electricity are in place.
