Coolers are often made with cooling water containing calcium, magnesium ions, and carbonates. When this cooling water flows over metal surfaces, carbonates are formed. Additionally, dissolved oxygen in the cooling water causes metal corrosion, forming rust. The formation of rust and scale reduces heat exchange efficiency. In severe cases, it becomes necessary to spray cooling water onto the exterior of the casing. Excessive scaling can clog pipes, rendering heat exchange ineffective. Research data shows that scale deposits have a significant impact on heat transfer losses. Increased scale buildup leads to higher energy costs, highlighting the need for energy conservation, extended equipment lifespan, and reduced production time and expenses.
Traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water cleaning, and chemical cleaning (acid washing) have long presented numerous problems: they cannot completely remove scale and other deposits; acid corrodes equipment, creating leaks; residual acid causes secondary corrosion or under-deposit corrosion, ultimately leading to equipment replacement; furthermore, cleaning wastewater is toxic and requires substantial investment in wastewater treatment.
