Cooling towers are essential in industrial settings, ensuring efficient heat rejection and stable production. However, maintenance is crucial to avoid fouling and equipment contamination. This guide outlines rapid maintenance methods for both open and closed-circuit cooling towers.

Maintenance of Open-Type Cooling Towers

Open-type cooling towers expose process cooling water to the atmosphere, leading to potential contamination. The supply process may also increase CaCO3 levels, causing fouling and production instability.

Steps for Maintaining Open-Type Cooling Towers

  1. Clean the Basin: Remove impurities at the bottom of the basin.
  2. Clean the Spray Pipe: Ensure it is free from blockages.
  3. Circulate Cleaning Agent: Use a cleaning agent with water to wash the system.
  4. Add Antifoaming Agent: This eliminates foam during operation.
  5. Check Heat Exchanger: Ensure the heat exchanger is clean.
  6. Neutralize pH: Add a neutralization agent to achieve a pH value of 7.

Disadvantages of Open-Type Cooling Towers

  • Hard to detect issues.
  • Ineffective use of cleaning agents.
  • Potential for acid washing damage.
  • Equipment breakdowns due to impurities.
  • Increased maintenance costs due to frequent issues.

Maintenance of Closed-Circuit Cooling Towers

Linkcooling's closed-circuit cooling towers use a heat exchange coil to separate the cooling system into an "inner water system" and an "outer water system," keeping the process fluid clean and contaminant-free. This design ensures high efficiency in production processes.

Advantages of Linkcooling Closed-Circuit Cooling Towers

  • Utilizes #304 stainless steel for durability.
  • Features detachable and simple maintenance components.
  • Equipped with an anti-fouling device to reduce coil scale.

Steps for Maintaining Linkcooling Closed-Circuit Cooling Towers

  1. Distribution Tube

    • Open the device case.
    • Turn the sprinkler tube 90° counter-clockwise.
    • Ensure the spray hole faces upward when reassembling.

  2. Fill :

    • The fill is piece-by-piece and located under the sprinkler tube.
    • Use a screwdriver to remove it and clean out any dirt.

  3. Heat Exchanger Coil

    • Open the intake louver underneath.
    • Clean using a high-pressure washer.

  4. Clean the Basin

    • Thoroughly clean the basin before operation to avoid reusing dirty water.
