Water-cooled chiller small size, large refrigeration capacity, the use of imported compressor, low temperature performance is good, reliable and durable, products according to the characteristics of industrial applications design, built-in low-temperature circulating water pump and stainless steel refrigerated water tank, easy to use, all materials in contact with water are made of anti-corrosion materials, can prevent rust, corrosion, microcomputer LED quantity controller, with temperature display, set temperature, automatically adjust the frozen water temperature and compressor delay protection function, the selection of good contactors, relays and other electrical components, equipped with perfect indicators, Switch, operation at a glance, built-in electronic water level indication and alarm device, low water level automatic alarm, the operator through the control panel can grasp the water level of the refrigerated water tank, timely water replenishment, modular design, each compressor system independent, even if a system problems, will not affect the normal work of other systems. 1. The compressor of the unit adopts the original imported brand of French Maneurop, Copeland (Copeland (Copelen)/Carrier (Carrier), Germany BITZER (BITZER) and other low-temperature compressors; 2. Use refrigerants such as R404A, R410a, R22/R407C, etc., to meet the refrigeration temperature and environmental protection requirements; 3. Temperature selection range: can provide process frozen water between -5 °C ~ -60 °C (users according to different production needs, select different outlet water temperature unit specifications; 4. According to the needs of users, a variety of refrigerants (frozen water) can be selected: ethylene glycol aqueous solution, alcohol, ternary mixed solution and other alcoholic refrigerants, and the evaporator can also be designed according to anti-corrosion requirements and use calcium chloride aqueous solution.
