380V Water Cooled Screw Chiller 50HZ / 60HZ Screw Compressor Chiller

Screw chiller is a kind of commonly used industrial refrigeration equipment, whose function is to absorb the heat in the air and achieve the cooling of air. Screw chiller adopts screw compressor as the compressor, which has the advantages of high efficiency and energy saving, stable operation, low noise, simple maintenance and so on, and is widely used in industrial refrigeration field.

The working principle of screw chiller is to compress the low temperature and low pressure vapour into high temperature and high pressure gas by screw compressor, then dissipate the heat and cool into liquid through condenser, and then decompress into low temperature and low pressure vapour through expansion valve, and the cycle is repeated to achieve the purpose of cooling. Screw chiller has the feature of high efficiency and energy saving, which can ensure the cooling effect and reduce energy consumption at the same time.

Screw chiller is widely used in industrial production of air conditioning, refrigeration equipment, machine tools, injection moulding machines, laser machines and other fields, can provide stable temperature and humidity conditions for the production environment to ensure the normal operation of equipment. In some special environments, 200HP screw chiller can also be used with other equipment to form a fully automated temperature control system to achieve remote monitoring and management, improve production efficiency and product quality.

Performance Features

Efficient and precise temperature control:

Can provide 5-35 ℃ out of water, precise adjustment of temperature ± 1 ℃; four-segment or no-segment control, automatic energy regulation (25%-50%-75%-100%), reliable operation, high energy efficiency ratio; microcomputer precision intelligent control, through the touch screen on the set of precise control and perfect protection, the interface displays the set of operating conditions, parameter settings, alarms, etc., at a glance, easy to operate, with RS485 remote communication function.

High-quality core parts:

Selected original imported brand-name semi-closed screw compressor, good performance, low noise, according to customer needs using a single machine or multi-machine combination, the compressor can be based on the load changes, automatic alternating operation, balancing the number of hours of operation of the compressor, greatly extending the life of the unit; copper pipe using internal and external threaded enhancement of the tube, enhance heat transfer capacity, good cooling effect, evaporator cylinder body with insulation board insulation, non-condensation, less loss of cold, smooth surface, easy to clean and maintain the copper pipe. Smooth surface, easy to clean and maintain; the use of American ALCO, Danish Danfoss and other international first-class brand accessories, excellent performance, safety and environmental protection.

Comprehensive safety protection:

With compressor delay start protector, compressor frequent start protector, compressor overheating protector, overload protector, high and low voltage protector, anti-freeze switch, fusible plugs, etc., to ensure the normal operation of the unit, with a lack of phase/reverse-phase protection, lack of water/insufficient flow protection, low temperature/anti-freezing protection and other functions.

Industry wide application:

Applied to large-scale production lines in injection moulding, electroplating, food, medicine, new energy, new materials and other industries.
