Product description:

Water-cooled screw chiller because of its key components - the use of screw-type screw-type water-cooled screw chiller, the unit from the evaporator out of the state of the gas refrigerant; compressed by the compressor after compression, into a high temperature and high pressure state. Compressed gas refrigerant, in the condenser, isostatic cooling condensation, after condensation into liquid refrigerant, and then through the throttle valve to low pressure, into a gas-liquid mixture. Which low-temperature low-pressure liquid refrigerant, in the evaporator to absorb the heat of cold matter, re-become a gaseous refrigerant. The gaseous refrigerant is reintroduced into the compressor via piping to start a new cycle. This is the four cycles of the refrigeration cycle. It is also the main working principle of the screw chiller.

 

Application areas

Dawson air - cooled screw chillers. Widely used in chemical, extrusion, aluminum processing, food processing, medicine, refrigeration and other needs of refrigeration and cooling areas. Davos is committed to refrigeration for many years, with more than industry technical elite. Continuous improvement of the product to improve. I am the Secretary for the whole process to provide customers with the selection program and installation of all-round technical support.

 

Features:

1 use of imported international brands BITZER Germany (Bitzer) Taiwan HANBELL (Han Zhong) efficient energy-saving compressor matching high-quality condenser and evaporator, high efficiency and stable performance Low noise long life Industrial PLC unit centralized control, with the compressor energy ratio, can be timely and accurate control unit cooling capacity and cooling load matching to ensure the best efficiency of the unit to run and reduce operating costs.

2 internal integrated water temperature low temperature and low pressure anti-freeze phase delay start reverse phase overload motor overheating oil pressure and many other security protection and processing functions.

3 full Chinese operation interface, menu prompts, can be set up the unit running status, home appliances operating environment.

4 capacity control can be used four-stage (100% -75% -50% -25%) or three (100% -66% -33%) and no-stage control system.

5 unique built-in hydraulic system, no oil pump to ensure that the compressor to maintain the best lubrication effect, oil separator with double filter, filter effect is good, thermal converter can play the maximum capacity.

6 efficient internal thread copper tube, enhance the heat transfer effect, more energy efficient. Using the latest CAD / CAM design and processing technology, CNC machining center production is completed, compact, small size 15, durable months. U-type structure of the heat transfer tube bundle, to facilitate maintenance, to prevent the phenomenon of refrigerant leakage.
