Technical characteristics of screw industrial chillers

1, using a semi closed 5:6 asymmetric double screw compressor are advanced, motor, compression chamber integration, no seal leakage phenomenon;

2, the compressor uses the star - Triangle step-down start to avoid the impact of the grid;

3, multi segment automatic control refrigeration capacity adjustment

4, heat exchanger imported efficient heat exchange copper tube, high heat transfer efficiency;

5, equipped with a liquid injection system can effectively reduce the temperature of the compressor, greatly improving the efficiency of the unit under low temperature conditions.

6, import PLC man-machine interface for LCD touch screen, graphics display, easy to operate, Chinese and English optional. Preparation of RS485 GB standard communication interface, can be connected with the DCS system, and can access the entire factory automation network for remote control and monitoring.

7, automatic detection of water temperature or water temperature by controlling the compressor capacity regulating valve, automatically adjust cooling capacity of the unit, more energy efficient operation.

8, automatically record the first 20 fault alarm points, convenient maintenance personnel timely judgment and maintenance unit.

9, low noise, small vibration, according to industry standard design, suitable for full year 24 hours operation.

10, the machine running parts only screw bearings, maintenance costs are very low, long life.
