Application :
It can be widely used in many industries in industrial production.
Surface treatment industry: mainly used for profile oxidation, hard oxidation, electrophoretic coating, zinc plating, tin plating, nickel plating, gold plating, silver plating, acid copper plating, vacuum plating, ion plating, glass plating, etc.
2. Plastic and plastic industries: including injection, extrusion, bottle blowing, compression, film blowing, shower film, calendering film, casting film, opening, leather embossing, etc.
3. Machinery manufacturing industry: used in CNC machine tools, coordinate boring machines, machining centers/modular machine tools and various precision machine tools, grinders, milling machines, drilling machines, polishing, grinding, casting, high frequency welding, laser welding, electronic chips, circuit board manufacturing, ultrasonic cleaning, printing and dyeing, ink production, paper making, glass processing, concrete mixing, etc.
4. Textile and chemical fibre industry: The main technological links of application are raw material slicing, drying, yellowing machine, mixer, dissolving machine and air static adjustment.
6. Solar photovoltaic industry: In the production of solar photovoltaic products, the necessary equipment for cooling water chillers are vacuum pump, wool making, PECVD, diffusion, etching, screen printing, polycrystalline furnace, single crystal furnace, polycrystalline silicon, monocrystalline silicon, square cutter, slicer, ingot furnace and so on.
7. Processing can be customized according to different requirements of customers.
1. International well-known compressors: the use of international well-known brand fully enclosed high-efficiency flexible scroll compressor, simple compression components without wear, small moment change, high balance, energy-saving, efficient, stable and reliable, easy to operate and easy to achieve automation control;
2. Anti-corrosion fin of air-cooled heat exchanger: adopting anti-corrosion hydrophilic aluminum foil, double flanging and expanding process, copper tube and fin are more closely contacted, and heat transfer efficiency is high. There is no need to install additional cooling water pumps and towers. They are reliable in operation, convenient in cleaning, strong in cooling capacity, low in noise, long in life and easy to operate. They are especially suitable for use in areas where water resources are scarce or water quality is high in hardness.
3. Evaporator: Using steel-plastic composite shell-and-coil heat exchanger, heat exchanger tube is a high-efficiency internal threaded tube, which is a high-tech small channel product developed from international heat transfer enhancement technology. The special pipe arrangement makes the heat transfer coefficient reach the leading level in the field of heat exchanger at present, and can maximize the operation efficiency of the unit. The shell is steel-plastic composite, and the water surface is sealed engineering plastic. It has strong corrosion resistance and long service life. After many freezing tests, no internal and external cracks were found in the special designed structure, and the frost resistance was excellent. The shell is removable and easy to maintain and clean.
4. Corrosion-resistant units: using high-efficiency anti-corrosion evaporator, direct cooling without any secondary heat exchange equipment, energy-saving than ordinary units more than 36%, shorter refrigeration time, more accurate temperature control, truly achieve energy-saving and efficient.
5. Control system: Industrial-level centralized control system, all-Chinese operation interface, menu prompt easy to operate, can view the operation status of the unit at any time, adjust the working mode, accurately control the matching of refrigeration capacity and cooling load, ensure the unit to operate with the best efficiency and reduce operating costs. Internal integration of water flow, low temperature, high and low pressure, anti-freezing, reverse phase, delay start, overload, over-temperature, oil pressure difference and other security protection functions. Accurate control can control the temperature in the range of (+1). It is easy to operate, safe and reliable.
6. Electrostatic spraying shell, fully enclosed box structure, beautiful and generous shape.
