Low-temperature screw chiller is a kind of equipment specially used for refrigeration, which is mainly applied to the occasions that need low-temperature cooling in the process of industrial production, such as chemical, pharmaceutical, food processing and other industries. This kind of chiller adopts the screw compressor as the main refrigeration element, which has the advantages of stable work, high efficiency, energy saving and environmental protection.
The working principle of low-temperature screw chiller is to use the screw compressor to inhale the low-temperature refrigerant, compress it and then exotherm it through the condenser to cool it into liquid state, and then evaporate it by cooling down through the throttle valve to absorb the heat and achieve the effect of refrigeration. Throughout the refrigeration cycle, the refrigeration effect of the chiller is adjusted by controlling the evaporation temperature, condensation temperature and other parameters.
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.
