Water-cooled ScrewCold Water CoolerGroup is a demand for -45℃~0℃ refrigerant refrigeration equipment, especially in recent years, the impact of the safety of ammonia refrigeration, water-cooled screw chillers by the user's favor, the unit uses non-toxic, non-flammable and explosive refrigerant R22, R134a, r404a, The cryogenic chiller is suitable for a variety of refrigerant: ethylene glycol solution, calcium chloride solution, sodium chloride solution, etc. also, the industry is also known as ethylene glycol low-temperature unit or brine low-temperature Unit, the unit is widely used in food refrigeration, chemical technology, bio-pharmaceutical, energy technology, industrial refrigeration and other industries. water-cooled screw-type cryogenic chiller uses a dedicated Han-clock screw compressor, 7-inch touch screen control, suitable for a long time in low temperature operating conditions stable operation, long life. Its core is 5:6 ultra-high efficiency spiral rotor compressor, with high speed (3000~4500r/min), more energy-efficient than the general compressor 20%~30%, reliable and efficient operation, easy maintenance, accurate energy control, wide application, its unit refrigeration volume of small, light weight, small footprint, Gas pulsation Small, stepless energy regulation control, according to the user's different cooling requirements of the automatic adjustment of output, energy saving and consumption.
At the same time, according to the requirements of the use of design: Ultra-low temperature, anti-corrosion, explosion-proof type of special industrial screw-type low-temperature chiller, can meet different temperatures, a variety of industries, the requirements of the process of refrigeration.
Our water-cooled screw type cryogenic chiller matching Bitzer (Germany Bitzer), Hanbell (Taiwan Han Zhong) and other world famous screw compressors. The utility model has the advantages of smooth and reliable operation, low efficiency, good performance, low vibration noise, energy saving, convenient maintenance and long life. According to customer needs and the size of the cold, the use of stand-alone or multiple machine combination. Compressor can be changed according to load, automatic alternating operation, stepless Energy Regulation (25%~100%), automatically balance the operating hours of each compressor, greatly extend the service life of chillers.
High efficiency shell-tube evaporator and shell-tube condenser
Evaporator copper tube with internal and external thread-type reinforcement tube. There are threads on the copper tube surface, the outer surface of copper tube is smooth, the cooling effect is good, the evaporator barrel body is insulated with the 20mm thick PE insulation board, does not dew, the cooling quantity loses less; the condenser adopts the external thread copper tube, the heat transfer effect is good, makes the water-cooled screw type Chiller machine run the energy efficiency ratio to
