50 horsepower air-cooled screw chiller

In industrial applications, cooling pumps for chilled water or other liquids are operated through processes or laboratory equipment. Industrial chillers are used in various industries to control the cooling of products, mechanisms, and factory machinery. They are commonly used in the plastic industry for injection molding and blow molding, metal processing cutting oils, welding equipment, die-casting and machining, chemical processing, pharmaceutical formulation, food and beverage processing, papermaking, cement processing, vacuum systems, X-ray diffraction, power supply and power plants, analytical equipment, semiconductors, compressed air and gas cooling. They are also used for cooling high thermal energy in specialized engineering projects such as magnetic resonance imaging machines and lasers, and in hospitals, hotels, and campuses. Industrial application chillers can be centralized, with each unit cooling to meet multiple needs, or dispersed in each application or device with its own refrigeration unit. Each method has its advantages. It may also have a combination of central and decentralized refrigeration units, especially when the cooling requirements are the same for certain applications or uses, but not all.

Frozen water is used to cool and dehumidify large commercial, industrial, and institutional alliance (CII) facilities in the air. The chiller unit can be water-cooled, air-cooled, cooled, or evaporative. Water cooled chillers are incorporated into cooling towers to improve the thermodynamic efficiency of refrigeration compared to air-cooled chillers. This is due to high temperatures or the wet bulb temperature of nearby air, rather than rejecting high, sometimes much higher, dry bulb temperatures. Evaporively type refrigerators provide better efficiency than air cooling, but lower than cold water.

Qingjin Refrigeration brand air-cooled screw chiller is used for:

Laser, chemical, electroplating and oxidation, precision equipment, ink, printing, papermaking, hardware, casting, bottle blowing, injection molding and vacuum forming industries, food cleaning and freezing, pharmaceutical industry, electronic circuit boards.

Characteristics of air-cooled screw refrigeration unit:
1、 Compressor

1、Adopting German Bitzer/Taiwan's revival/Hanzhong semi enclosed screw compressors and original imported single screw and twin-screw series compressors.

2、twin screw5：6The gear ratio and advanced linear design are energy-saving and efficient.
3TheEfficient active valve energy control, achieving graded or stepless energy control. Balanced design ensures ultra quiet and smooth operation.
4、Strict handling of moving parts, special oil balance block design for exhaust, long maintenance cycle, and trouble free operation41000More than hours.
5、Efficient oil separator, with an oil output of less than1.5%Effectively improve the heat exchange between the evaporator and condenser, making them more energy-efficient and durable.

IINew high-efficiency evaporator
The new high-efficiency internally threaded copper tube enhances heat transfer efficiency and is more energy-efficient.
Apply expertiseCAD/CAMDesign and processing technology,CNCThe machining center has been completed, with a compact structure, small size, and durability. Convenient for cleaning internal scale and maintenance.
Dry evaporator, convenient for oil return, improves compressor life and system reliability.

3、 Air-cooled condenser
The heat dissipation fins are punched by high-speed punching machines, and the flipping quality is reliable. Secondary flanging ensures closer contact between the copper tube and fins, resulting in high heat transfer efficiency. The use of fully imported copper pipes and fully automatic elbow welding greatly enhances oxygen tightness and prevents refrigerant leakage. Especially suitable for use in areas with scarce water resources or high water hardness.

4、 Advantages of Qingjin Refrigeration brand air-cooled screw chiller products:
