Water cooled screw type industrial low-temperature refrigeration unit (-25 ℃)

Water cooled screw industrial low-temperature refrigeration unit (-25 ℃) is a series of ultra-low temperature refrigeration equipment launched by Nuo Leng Company for low-temperature refrigerants with demand (-90 ℃~0 ℃), especially the safety accidents that have occurred in ammonia refrigeration in recent years. Water cooled screw industrial low-temperature refrigeration units use non flammable, explosive, non-toxic refrigerants such as R22 and R404a

The water-cooled screw industrial low-temperature refrigeration unit is a series of ultra-low temperature refrigeration equipment launched by Nuo Leng Company for low-temperature refrigerants with demand (-90 ℃~0 ℃), especially the safety accidents that have occurred in ammonia refrigeration in recent years. The water-cooled screw industrial low-temperature refrigeration unit adopts non flammable and non explosivenon-toxicR22, R404a, etcrefrigerantThis low-temperature refrigeration unit is suitable for carrying refrigerants such as ethylene glycol solutions of different concentrations, calcium chloride salt solutions, sodium chloride salt solutions, etc; Also known as screw type ethylene glycol low-temperature unit or screw type in the same industrylow temperatureSalt water unitThis unit is widely used in industries such as food freezing and refrigeration, chemical technology, biopharmaceuticals, energy technology, and industrial freezing.
Water cooled screw typeLow temperature chillerThe group adopts a dedicated Hanzhong screw compressor with a 7-inch touch screen control, which is suitable for stable operation under low temperature conditions for a long time and has a long service life. The core of the compressor adopts a 5:6 ultra efficient double helix rotor with high-speed operation capability (3000-4500r/min), which is 20% -30% more efficient than traditional compressors. It has high reliability and efficiency, easy maintenance, precise energy regulation control, and a wide range of applications. Its unit cooling capacity is small in volume, light in weight, small in footprint, small in gas transmission pulsation, and stepless energy regulation control. It can automatically adjust the output according to different cooling capacity needs of users, saving energy and reducing consumption.At the same time, it can be designed according to usage requirements: ultra-low temperature, anti-corrosion, explosion-proof special industrial screw type industrial low-temperature refrigeration units, which can meet the requirements of different temperatures and various industries' process refrigeration.

The water-cooled screw industrial low-temperature refrigeration unit is equipped with world-renowned screw compressors such as BITZER (Germany) and HANBELL (Taiwan Hanzhong). It has the advantages of smooth and reliable operation, high efficiency with low faults, good performance, low vibration and noise, energy saving, easy maintenance, and long service life. According to customer needs and cooling capacity, single machine or multi machine combination can be used. The compressor can automatically alternate operation according to load changes, perform stepless energy regulation (25%~100%), automatically balance the operating hours of each compressor, and greatly extend the service life of the chiller unit.

Efficient shell and tube evaporator and shell and tube condenser

The evaporator copper tube adopts an internally and externally threaded reinforced tube. The surface of the copper tube has threads, the outer surface of the copper tube is smooth, and the cooling effect is good. The evaporator cylinder is insulated with a 20mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity; The condenser adopts externally threaded copper pipes, which have good heat transfer effect and increase the overall energy efficiency of the water-cooled screw chiller.

Intelligent PLC Computer Control System

The company has jointly developed a highly intelligent PLC computer touch control system with Siemens PLC, a world-renowned electrical control expert, based on the characteristics of the unit. It can be used for remote monitoring and control, and has multiple functions such as automatic loading and unloading, timed power on and off, and recording of fault causes; Easy to operate, connect the host to the power supply. Low failure rate, high safety factor, simple installation, system control can be adjusted in real time, intuitive and reliable.

Safe protective device

The protection system devices include: compressor delay start protector, overload protector, high and low pressure protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compressor frequent start protector, and abnormal indicator light to ensure the normal operation of the unit.

High quality refrigeration accessories

Refrigeration accessories such as expansion valves, solenoid valves, filters, etc. are all selected from the world's top brands SPORLAN (Poland, USA), ALCO (Ako, USA), DANFOSS (Danfoss, Denmark), etc., with excellent performance, safety and environmental protection.

Multiple refrigerant applications

The water-cooled screw industrial low-temperature refrigeration unit can use solutions such as ethylene glycol, propylene glycol, calcium chloride, sodium chloride, etc. as antifreeze refrigerants, and the system is safe and reliable.
