Finned tube evaporator coil adopts φ7.94mm, φ9.52mm, φ12.7mm, φ15.88mm or φ16mm copper pipe, white nickel copper pipe, stainless steel pipe; Fin materials have no coating aluminum foil, hydrophilic aluminum foil, epoxy resin anticorrosive aluminum foil, copper foil, stainless steel sheet for customers to choose, to meet the needs of different working conditions and various combinations.
Graphene-coated anti-corrosion evaporator coils are also called nano-coated evaporators. In order to improve the corrosion resistance of finned evaporators, it is necessary to add a layer of graphene material to the surface of the finned evaporators, thereby improving the corrosion resistance performance of bare aluminum fin evaporators. Foshan Linklong Technology Co., Ltd's nano coating anticorrosion evaporator coil uses aluminum foil made of nano-protection, which can be used in combination with copper pipe anti-corrosion treatment to provide three-dimensional protection equipment and extend the service life of the equipment.
Principle of finned tube evaporator coils:
Fin tube evaporators are a device used in the liquid evaporation process. Its principle is to heat the liquid to reach the boiling point, so that the water or other components in the liquid are evaporated. During the evaporation process, the temperature of the liquid will rises and produces water vapor. When the water vapor reaches a certain concentration, the evaporated gas can be re-condensed into a liquid through the condenser and returned to the evaporator coil to continue the cycle. The function of the condenser coil is to convert the refrigerant from gaseous state to liquid state and release a large amount of heat. In a refrigeration system, the fin tube condenser is usually located after the compressor and is an important part of the refrigeration cycle.
Evaporator coil can quickly convert liquid refrigerant into gaseous refrigerant, thereby absorbing a large amount of heat and achieving a rapid cooling effect. In addition, finned evaporators can be designed and manufactured according to specific application needs to meet different cooling capacity and temperature requirements.

The anti-corrosion evaporator coil customized by Foshan Linklong Technology Co., Ltd. has the following advantages:
1. Long-term corrosion resistance, suitable for various chemical environments, reducing the maintenance cost of epoxy resin corrosion-resistant evaporators. ;
2. Excellent energy-saving effect, greatly reducing the rising energy consumption caused by corrosion;
3. Doubling the service life of evaporators, condensers, surface coolers and heat exchangers in severely corroded areas, such as ports, islands, oil and gas, power generation, chemical industry, etc.;
4. The evaporator coil and surface air cooler of special air conditioners can be changed to copper tube aluminum fin structure, which greatly reduces the cost of materials;
5. It is not easy to frost, prolongs the defrosting cycle, can effectively reduce energy consumption, and is suitable for freezing and refrigeration, food refrigerators, etc.;
6. Anti-frost and anti-bacterial, with significant advantages in food, medicine, fresh-keeping and other fields, improving health and reducing energy consumption;
7. Anticorrosion evaporator coil has the function of self-cleaning. It does not stick to dust, does not stick to oil, and prevents scale formation. Generally, it can be rinsed with clean water, saving daily maintenance and cleaning and maintenance work;
8. Reduce operating and after-sales service costs caused by problems such as corrosion and defrost.

Application fields of fin-tube evaporator coils:
Corrosion resistance evaporator coil is widely used in chemical, pharmaceutical, food and other fields. In these fields, equipment that needs to use heat exchange equipment includes reactors, dryers, distillation towers, etc. These devices need to transfer heat to the heated liquid or gas to realize the reaction, drying, distillation and other processes. The efficient heat transfer and high corrosion resistance of epoxy resin foil evaporators make them ideal for these devices.
In the chemical industry, epoxy resin aluminum foil evaporators are often used in reaction kettles to transfer heat to the reactants to control the temperature and temperature distribution of the reaction to ensure the smooth progress of the reaction.
In the field of pharmaceuticals, copper tube aluminum foil evaporators are often used in dryers to transfer heat to drug solutions to achieve drug drying and concentration.
In the food field, nano-coating aluminum foil evaporators are often used in distillation towers to transfer heat to food raw materials to achieve distillation and separation of food raw materials.
In short, aluminmum fin tube evaporator heat exchanger is an efficient, corrosion-resistant, high-temperature stable, wear-resistant, thermally stable and environmentally friendly heat exchange equipment, which is widely used in chemical, industrial, pharmaceutical and food fields. Evaporator coil heat transfer equipment can not only improve production efficiency, reduce equipment maintenance costs, but also guarantee product quality and safety.
