You schedule a chemical clean of the eliminators, dropping amp draw by 12% and extending motor life by years.
A 500-ton induced draft tower is drawing 15% more current (amps) than last month. The water is cold enough, but the fan is laboring. cooling towers principles and practice pdf
The PDF reminds you that fan amp draw increases with air density or resistance. High resistance means blocked airflow exit. You schedule a chemical clean of the eliminators,
You turn to the chapter "Drift Eliminators." The cross-section diagram shows that drift eliminators (chevron-shaped) collect water droplets. If they are coated with algae, the velocity pressure increases. The PDF reminds you that fan amp draw
It answers the critical questions that tachometers and thermometers cannot: Why is the drift velocity too high? How do I balance water flow to three cells when one is offline? What is the maximum allowable calcium hardness given my current silica level?
