Screw chiller

Description

Applicable industry of screw chiller
▲ Cold injection molding, extrusion, bottle blowing, thermal molding, mechanical cutting, noncutting, casting, surface treatment, laser technology, welding, plastic molding, etc;
▲ Temperature reduction of ferry oxidation equipment, plastic, electronic manufacturing, electroplating, pharmaceutical and chemical industry, ultrasonic cooling, printing, and other chemical industries

Features of screw chiller:
▲ The screw-type chilled water compressor adopts an international brand, a new type of high-efficiency spiral rotor compressor, which is 20% – 30% more efficient than ordinary compressors and has obtained patents in Europe, America, and many countries and ISO9001 international quality certification.
▲ High efficiency 5:6 patented asymmetric rotor tooth profile.
▲ Four segments (100% – 75% – 50% – 25%) or three segments (100% – 66% – 33%) and nonsegment control systems can be used for capacity control.
▲ A timely a-type axial thrust balance drum combination design of 11 bearings is adopted, which greatly improves the bearing life by 2.5-3.5 times.
▲ The high-efficiency silicon steel sheet and special groove design are adopted, and the internal and external omnidirectional design cooling channels are equipped so that the compressor motor can play the highest efficiency under any load.
▲ The unique built-in oil pressure system ensures that the compressor maintains the best lubrication effect without oil pump.
▲ The oil separator adopts the double layer filtering mode, with a good oil filtering effect, and the heat exchanger can give full play to its capacity;
▲ A variety of refrigerants are available. In addition to R22 refrigerant, R134a, R407c, and other environmentally friendly refrigerants can also be selected.
▲ Full-text bit compression volume ratio (Vi=2.2/2.6/3.0/3.5) is optional, which can effectively avoid additional energy consumption caused by over-compression
