Why Cooling Tower Cleaning is Important

• Efficiency: Scale deposits, sludge, and biological growth (such as algae and bacteria) can reduce heat transfer efficiency, resulting in increased energy costs.

• Health & Safety: Unmaintained cooling towers can harbor Legionella bacteria, which causes Legionnaires' disease.

• Compliance: Many local regulations and industry standards (such as ASHRAE 188, OSHA, or local water quality regulations) require regular cleaning and maintenance.

• Durability: Cleaning prevents corrosion and damage to structural parts, extending the life of the cooling tower.

Common Cleaning Processes

1. Inspection & Preparation

   • Assess the level of dirt, corrosion, and scale.

   • Perform lockout/tagout safety procedures.

2. Initial Draining & Cleaning

   • Drain the catch basin and remove large debris.

3. High Pressure Cleaning

   • Surfaces, fill media, drift eliminators, and sumps are cleaned using a high pressure machine or vacuum.

4. Scale Removal & Chemical Treatment

   • Using biocide, algaecide, or scale removal chemicals as required.

5. Refilling & Re-Operation

   • Cooling towers are flushed, refilled, and then re-run with appropriate water treatments.

Recommended Cleaning Frequency

• Light load systems: Once per year (before summer).

• Heavy load/humid climate: Twice per year.

• Hospitals, data centers, or high-risk locations: Quarterly inspection and cleaning as needed.

Tips for Choosing a Cleaning Service

Choose a service provider that has:

• Certification in Legionella risk management.

• Experience with your cooling tower make/model.

• Use of environmentally friendly and regulatory compliant chemicals.
