Upd - Cooling Tower Overflow

The consequences of ignoring overflow extend far beyond the water bill. Cooling tower water is treated with biocides, corrosion inhibitors, and scale preventatives. When the tower overflows, these expensive chemicals are literally washed down the drain. Furthermore, the introduction of excessive fresh (makeup) water changes the chemistry of the system, potentially lowering the cycles of concentration. This introduces new minerals and oxygen, accelerating corrosion rates and scale formation on the fill media and heat exchangers. Left unchecked, the tower’s efficiency plummets, requiring more energy to achieve the same amount of cooling.

The most frequent culprit is a mechanical float valve that has become stuck, misaligned, or corroded. If the valve fails to close tightly when the basin reaches its set level, makeup water continues to flow indefinitely. cooling tower overflow

Cooling tower overflow is more than just a minor plumbing hiccup; it is a signal of systemic inefficiency that can lead to staggering water loss, structural damage, and regulatory fines. For facility managers and engineers, understanding why a tower spills over—and how to stop it—is critical for maintaining a sustainable and cost-effective HVAC or industrial process system.
