Plate coolers are widely used in industries such as machinery manufacturing, cement, metallurgy, power generation, and petrochemicals. Their stable performance and high heat exchange efficiency make them an essential part of many industrial cooling systems. However, improper cleaning and maintenance methods can significantly reduce their service life and even lead to irreversible damage.

Based on years of industry experience, Jiangsu Yuling Machinery Technology Co., Ltd. summarizes the most common problems encountered during plate cooler maintenance and provides professional insights to help users avoid costly mistakes.

Common Problems in Plate Cooler Cleaning and Maintenance

1. Scale Cannot Be Completely Removed

During long-term operation, minerals and impurities in the cooling medium easily form scale on the heat transfer surfaces. Conventional cleaning methods often fail to fully remove stubborn scale deposits, which reduces heat exchange efficiency and increases energy consumption.

2. Sediment Accumulation Inside the Plate Cooler

Sediment such as sludge, rust particles, or solid impurities may accumulate inside the plate channels. If not thoroughly removed, these sediments can cause partial blockage, uneven flow distribution, and localized corrosion.

3. Chemical Cleaning Causes Equipment Corrosion

Chemical cleaning is commonly used to dissolve scale and deposits, but improper selection or excessive concentration of chemical agents can corrode plate materials and sealing components.

Even more critically, if chemical solvents are not completely flushed out after cleaning, residual chemicals may cause secondary corrosion during subsequent operation. In severe cases, this can lead to plate deformation, leakage, or even total scrapping of the plate cooler.

4. Environmental Pollution from Waste Cleaning Liquids

Waste cleaning liquids generated during chemical cleaning often contain large amounts of toxic or hazardous substances. Improper discharge of these liquids can cause serious environmental pollution and may violate local environmental regulations.

Professional Solutions Require Professional Equipment

To ensure safe, efficient, and environmentally friendly maintenance, it is essential to adopt scientific cleaning methods and professional cooling equipment solutions. Mechanical cleaning, optimized flow design, and environmentally compliant cleaning processes can significantly reduce corrosion risks and environmental impact.
