Cooler Routine Maintenance

- Apr 15, 2019-

Most of the coolers contain calcium, magnesium and acid carbonates due to cooling water. When cooling water flows through the metal surface, there is a formation of carbonate. In addition, oxygen dissolved in the cooling water can also cause corrosion of the metal to form rust. The heat transfer effect is reduced due to the generation of rust. In severe cases, it is necessary to spray cooling water outside the casing. When the scale is severe, the pipe will be blocked, and the heat exchange effect will be lost. The research data shows that scale deposits have a great impact on the heat transfer loss. As the sediment increases, energy costs will increase, saving energy, extending the service life of the equipment, and saving production time and costs.

For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc., have many problems when cleaning equipment: it is impossible to completely remove deposits such as scale, and acid corrosion causes corrosion of equipment. The residual acid causes secondary or scale corrosion on the material, which eventually leads to replacement of the equipment. In addition, the cleaning waste liquid is toxic and requires a large amount of funds for wastewater treatment.

Cleaning the condenser with cleaning agent is efficient, environmentally friendly, safe and non-corrosive. It not only has good cleaning effect but also no corrosion to the equipment, which can ensure the long-term use of the condenser. Cleaning agent (special addition of wetting agent and penetrating agent can effectively remove the most stubborn scale (calcium carbonate), rust, grease, slime and other sediments produced in water equipment, without causing harm to the human body. It will not cause corrosion, pitting, oxidation and other harmful reactions to steel, copper, nickel, titanium, rubber, plastic, fiber, glass, ceramics, etc., which can greatly extend the service life of the equipment.
