Water-cooled screw chiller is a kind of high-efficiency and energy-saving refrigeration equipment, which is widely used in industrial production and commercial fields. It discharges heat by water cooling and adopts the working principle of screw compressor, which has the advantages of high refrigeration efficiency, stable operation and low energy consumption.
Water-cooled screw chiller is mainly composed of compressor, condenser, expansion valve and evaporator. In the working process, the compressor will be low-temperature and low-pressure steam inhalation and pressurisation, forming a high-temperature and high-pressure gas, and then through the condenser and the cooling water for heat exchange, cooling and condensing into a liquid state, and then through the expansion valve cooling and decompression, into a low-temperature and low-pressure steam, so as to achieve the cooling effect.
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.
