Jiangsu low temperature chiller high configuration, quality assurance, low temperature chiller for the pharmaceutical, chemical, beverage bottling, food processing, photovoltaic and other special industries, and design a new generation of low-temperature refrigeration equipment, the temperature range of 30 degrees to minus 120 degrees between arbitrarily adjusted automatically. The cooling range 14200 - 2036600Kcal / h, chilled water temperature range of-350C to-100C. Refrigeration system pressure control and safety valve device to ensure the safety of crew work. The application areas of pharmaceutical, chemical, petroleum, food, freezing, cold storage and other fields. The unit features (1) high temperature: minimum evaporating temperature reached-50C, mainly applies to large and medium-sized supermarkets, hotels, restaurants, refrigerated display cases, food preservation, library, hospital, pharmaceutical, electronics and other industries. Low temperature screw chiller (2) medium temperature: minimum evaporating temperature up to-100C, is mainly applied to the food processing industry, beverage industry, cold storage, hospitals, pharmaceutical, electronics and other industries. (3) Low temperature: minimum evaporating temperature up to-200C, mainly applicable to the needs frozen, fresh, shelf life of a large cold storage, transportation, hospitals, pharmaceuticals, electronics and other industries. (4) ultra-low temperature type: lowest evaporation temperature of-400C, mainly applicable in frozen, fresh, cold storage, hospitals, pharmaceuticals, electronics and other industries, (5) investment less: a modular design, reduce late early investment and equipment maintenance maintenance fee. (6) Intelligence: microcomputer touch screen control system, can be connected to households central control system, all-round monitoring unit operation. Cold water chiller glycol as the secondary refrigerant, 5 ... -50 ℃ chilled liquid to low temperature and low humidity provide the necessary cold source. When winter still refrigeration unit can be equipped with a special control system, the unit remains the cooling operation at low temperature of -50 ℃ environment. Low temperature chiller saline as the carrier refrigerant, 5 --- 50 ° C chilled liquid low temperature 5 - 90 ° C chilled liquid cryogenic chiller chiller refrigerant contained, alcohol or dichloromethane quality and cheap
