Anti-Corrosion Air Conditioner
Corrosion refers to the process of loss and damage of metal and non-metal under the action of surrounding medium (water, air, acid, alkali, salt, solvent, etc.), no matter where it is, corrosion problems are everywhere, corrosion problems bring high cost. Anti-corrosion air conditioner is an air-conditioning system specially designed to improve the production and living environment. The anti-corrosion air conditioner adopts abroad special anti-corrosion technology, which can prevent pollution corrosion and reduce unnecessary energy loss of heat exchangers. It is widely used in pulp and paper, energy and chemical, power generation, metallurgical industry, food storage and deep processing, sewage treatment, coastal salt spray corrosion environment.

Pulp and Paper Industry
The pulp and paper workshop is a high-humidity and highly corrosive working environment. It produces a large amount of corrosive gases such as water vapor, chloride, sulfur dioxide, chlorine dioxide and hydrogen sulfide in the process of pulping and paper making which has strong causticity. In particular, sulfur dioxide and chlorine dioxide gas may cause sulfurous acid or chlorous acid which is highly corrosive to the air conditioning system, causing corrosion of the air conditioning system, damage to the components, and leakage of the refrigerant. Directly causing the ambient temperature of the electrical room to rise, the shutdown and damage of electrical components and production equipment, causing huge economic losses to the enterprise.
In view of the special industrial environment of paper mills, based on years of anti-corrosion experience and philosophy, our company adopts high-corrosion-resistant accessories from R&D, design, two parts and various components, and carries out special anti-corrosion treatment on key parts of the system. Targeted year-round cooling design. It has been well received in the paper mill industry.
Energy and Chemical Industry
In the process of processing and application of fossil fuels, deep processing of coal, and deep processing of crude oil, various harmful corrosive gases such as dust, sulfur dioxide, ammonia, and hydrogen sulfide are generated. Sulfide corrosion is not isolated, and sulfur interacts with other corrosive media such as inorganic salts, naphthenic acids, nitrides, water, hydrogen, ammonia, etc. to form a complex corrosive environment. It will cause different corrosion to various system parts such as air conditioner casing, copper pipe, fins and fans.
With the experience of many years of on-site unit use, RISITA has cooperated with major research institutes for a long time. According to the different processing technologies of each chemical industry, it has developed anti-corrosion air conditioners for various dust and corrosive applications.
Power and Power Generation Industry
When the thermal equipment of a power plant is in operation, the medium in contact with various qualities of water, steam and flue gas has different parts and different characteristics of the medium. The operating conditions of the equipment change, the characteristics of the medium also change, and the various corrosive components in the medium will also cause serious corrosion to the equipment. The main corrosion comes from oxygen corrosion, acid corrosion, and concentrated corrosion of the boiler medium. , coal smoke corrosion and so on. Corrosive impurities and gases are particularly corrosive to air-conditioner enclosures, copper tubes and aluminum fins in corrosive environments.
Our company combines years of anti-corrosion experience and on-site use environment to develop professional anti-corrosion air conditioners for various corrosive environments, which can effectively prevent various types of corrosion in different sections of power plants.
Most of the metallurgical industry is used in high temperature, heavy load, high wear and specific corrosive environment. The production environment is harsh and the corrosion problems are prominent. For example, in the steel industry, chemical corrosion in high temperature environment such as slag, molten iron and blast furnace gas. In the electrolytic aluminum and electrolytic copper industries, the hydrogen fluoride, sulfur dioxide and other gases in the workshop are exposed to water to produce acidic corrosion such as hydrofluoric acid and sulfuric acid. Hydrometallurgy in the lead and zinc industry requires acid leaching, alkali leaching, salt leaching and other processes, and various acid and alkali corrosion. Corrosion is quite serious in the metallurgical industry system, causing serious economic losses to the enterprise.
Our company has been digging deep into the metallurgical industry for many years, constantly exploring and developing special anti-corrosion air conditioners for metallurgical industry, effectively preventing the corrosion of air-conditioning systems on site and greatly improving the service life of on-site air conditioners.
Food Storage and Deep Processing Industry
Food storage and deep processing industries, including grain storage, cooked food products, condiment manufacturing, corn deep processing, potato deep processing, sweet potato deep processing and other industries. Products include: soy sauce, sauce, cooking oil, starch, protein powder, starch sugar, edible alcohol, fuel ethanol, glutamic acid, lysine, xylitol, chemical alcohol, cellulose, vitamins and other thousands of varieties. Corrosive gases such as sodium chloride, sulfurous acid and phosphine are produced during production and storage, and copper, aluminum and iron in air conditioning equipment are corroded to varying degrees, which seriously affects the service life of air conditioners.
The company has penetrated the industry site for many years and developed special anti-corrosion air conditioners for food storage and deep processing industries, and targeted anti-corrosion treatment for air conditioners.
Sewage Treatment Industry
Contaminants cannot be effectively treated, which will seriously affect the production and life of residents, and the necessity of sewage treatment can be seen. The main corrosion of sewage is: acid ion corrosion, microbial corrosion, and pollution gas corrosion. Acid ion, chloride ion is one of the most powerful activators of steel. Chloride ion and water produce hydrochloric acid and are volatile. Sewage treatment process is accompanied by a large number of pungent gases, including ammonia, hydrogen sulfide, methane, humic acid, volatile phenols, benzene series and so on. Among them, hydrogen sulfide and ammonia react with water in the air to form a compound with strong corrosion. Therefore, the production equipment in this production environment does not effectively protect the corrosion, which affects the accuracy of the equipment, thereby affecting the production and reducing the life of the equipment. This results in greater economic losses.
The company developed a special anti-corrosion air conditioner suitable for sewage treatment sites for the corrosive environment of sewage treatment sites. After a large amount of feedback on the use of the site, the anti-corrosion effect is excellent, and the service life is 5 times that of the ordinary air conditioner.
Coastal Salt Spray Corrosion Industry
The marine environment is complex and variable, with varying degrees of corrosion impact on a wide variety of metallic materials. High humidity and high salt are the characteristics of the marine atmosphere. For air conditioner, the water vapor in the ocean atmosphere is easily attached to the surface of the air conditioner casing, copper pipe and heat exchanger under the influence of capillary action, adsorption and chemical condensation. A water film that is invisible to the naked eye is formed. The water film contains dissolved oxygen, chloride ions, sulfate ions and other salts, which cause corrosion of the air conditioner and affect the service life of the air conditioner.
After years of research and development, combined with the characteristics of the marine environment, the company produces special anti-corrosion air conditioners for the marine atmosphere. Whether it is at the seaside factory or the oil drilling platform in the sea, it can work well, stably and for a long time. To ensure the safety and stability of electrical equipment.
