Features:

1. The air-cooled screw machine uses a low-speed cooling fan to discharge heat smoothly, thereby reducing the sound to a minimum. The unit has low vibration and simple installation. It is suitable for areas where water sources are scarce, and no water tower is required.

2. The unit of the air cooled screw machine can realize intelligent program control according to the demand of the load, save energy consumption, adopt a full-touch screen human-machine interface, and accurately monitor. The unit adopts hierarchical or stepless energy control to achieve the highest energy efficiency ratio.

3. The unit of air cooled screw machine adopts imported brand-specific air-cooled semi-closed screw compressor. The operation is reliable, efficient, easy to maintain, accurate capacity control, wide application range. The system uses the latest asymmetric rotor tooth shape, and built-in differential pressure supply. Oil lubrication system: low vibration, low noise, high sealing performance.

4.Complete protection devices for air cooled screw machines: Compressor anti-frequent start, over-current relay protection, compressor motor over-heat protection, anti-freeze protection, sight glass, oil heating protection, compressor phase protection, high / low voltage protection , exhaust high temperature protection, safety valve, easy plug, cut-off protection, etc.


Chillers are commonly used in injection molding and blow molding in the plastics industry, metalworking cutting oils, welding equipment, die casting and machining, chemical processing, pharmaceutical development, food and beverage processing, paper making, cement processing, vacuum systems, X-ray diffraction, Power supply and power stations, analytical equipment, semiconductors, compressed air and gas cooling. They are also used to cool high thermal energy projects such as MRI and laser, and in hospitals, hotels and campuses.

 

Plastic industry: Accurately control the mold temperature of various plastic processing, shorten the cycle of beer and plastic, and ensure the stability of product quality.

 

Electronics industry: Stabilize the molecular structure inside the electronic components on the production line, improve the qualification rate of electronic components, and apply it to the ultrasonic cleaning industry to effectively prevent the damage caused by the volatilization and volatilization of expensive cleaning agents.

 

Electroplating industry: control plating temperature, increase the density and smoothness of plating parts, shorten plating cycle, improve production efficiency and improve product quality.

 

Machinery industry: control the pressure oil temperature of the oil pressure system, stabilize the oil temperature and oil pressure, prolong the oil quality use time, improve the efficiency of mechanical lubrication and reduce wear.

 

Construction industry: The chilled water for concrete is used to make the molecular structure of concrete suitable for the purpose of construction, and effectively enhance the hardness and toughness of concrete.

 

Vacuum coating: Control the temperature of the vacuum coating machine to ensure the high quality of the plated parts.

 

Food industry: used for high-speed cooling after food processing to adapt to packaging requirements. There is also a temperature for controlling the fermented food.

 

Pharmaceutical industry: It is mainly used in the pharmaceutical industry to control the temperature control of fermented drugs. Pharmaceutical enterprises should make full use of the chiller equipment, continue to strengthen technological innovation on the basis of exerting their advantages, and enhance the cost performance of the chiller to better serve the pharmaceutical sector.
