How far must the plume from cooling towers be from any ventilation inlet to avoid obstruction?

The correct distance for the plume from cooling towers to be from any ventilation inlet is 20 feet. This standard is essential to ensure that the steam or mist generated by cooling towers does not interfere with the air intake of ventilation systems.

By maintaining a distance of 20 feet, you help to minimize the risk of moisture and contaminants from the plume being drawn into the ventilation system. This can prevent potential issues such as reduced air quality, increased humidity levels, or even corrosion of the ventilation components over time.

Establishing a proper buffer zone not only aligns with best practices for HVAC system design but also adheres to health and safety regulations that aim to maintain optimal indoor air quality. Therefore, the 20-foot distance serves as a critical guideline to protect both mechanical systems and occupant comfort.
