60 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.

Characteristics of air-cooled screw chiller:
1、 Compressor
Adopting German Bitzer/Taiwan's revival/Hanzhong semi enclosed screw compressor and original imported twin-screw series compressor. twin screw5：6The gear ratio and advanced linear design are energy-saving and efficient.
Efficient active valve energy control, achieving graded or stepless energy control. Balanced design ensures ultra quiet and smooth operation.
Strict handling of moving parts, special oil balance block design for exhaust, long maintenance cycle, and trouble free operation41000More than hours.
Efficient oil separator, with an oil output of less than1.5%Effectively improve the heat exchange between the two devices, making them more energy-efficient and durable.

2、 New high-efficiency evaporator

The new high-efficiency internally threaded copper tube enhances heat transfer efficiency and is more energy-efficient.
Using new methodsCAD/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、 Microprocessor control system
Industrial gradePLCCentralized control of the unit, combined with the adjustable system of the compressor, can timely and accurately control the matching of the cooling capacity and cooling load of the unit, ensuring efficient operation of the unit and reducing operating costs. Internally integrated with multiple safety protection and treatment functions such as water cut-off, low temperature, high and low pressure, antifreeze, phase loss, delayed start, reverse phase, overload, motor overheating, oil pressure difference, etc. Full Chinese operation interface, menu style prompts, allowing for arbitrary setting of unit operation status, and a home appliance based operating environment.
