Low Temperature Screw Cooler

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
Intelligent PLC Computer control system
Company and the World electric control expert Siemens PLC automatic control company for the characteristics of the unit, the joint development of a high intelligent PLC computer touch control system, can do remote monitoring and control, with automatic loading and unloading, timing switch machine and record the reasons for the multiple functions, simple, host and power connection Low failure rate, high safety factor, simple installation, system control can be adjusted immediately, intuitive and reliable.
Powerful protective devices
Protection system devices are: Compressor delay start protector, overload protector, high and low voltage protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection relief valve, compressor overheating protector, compressor frequent start protector and abnormal indicator, to ensure the normal operation of the unit.
Domestic and foreign advanced refrigeration accessories
Refrigeration accessories such as expansion valve, solenoid valve, filter, etc. all selected the world's top brand Sporlan (U.S. Poland), ALCO (USA yike), DANFOSS (Denmark Danfoss), performance excellence, safety and environmental protection.
Adapt to a variety of refrigerant
HOT88热竞技The water cooled screw type cryogenic chiller can adopt the solution of ethylene glycol, propylene glycol, calcium chloride and sodium chloride as antifreeze coolant, and the system is safe and reliable.
