FAQs

Cooling tower maintenance audits should be conducted at least quarterly, with more frequent inspections during peak cooling seasons or in harsh environments.

Key areas include water quality testing, mechanical component inspection, fan and motor performance, fill media condition, and overall system cleanliness.

Cooling tower maintenance audits should be performed by qualified facility engineers, HVAC technicians, or specialized cooling tower maintenance professionals.

By identifying and addressing issues such as scale buildup, clogged nozzles, or inefficient fan operation, the audit helps maintain optimal heat transfer and reduces energy consumption.

Safety considerations include proper lockout/tagout procedures, fall protection measures, personal protective equipment usage, and awareness of potential biological hazards such as Legionella.
