What Not To Do

Use of of roll media and window screen stops the airborne debris however, because neither the roll media nor window screen is designed for high volume airflow, this tower is virtually starved of air flow, resulting in a large drop in static pressure and a significant reduction in cooling efficiency.

This tower has pre-filter media which has been framed to enable coverage over a cooling tower intake opening. This type of media is not designed for high volume airflow and will restrict air-flow and result in a drop in static pressure and loss of efficinecy. Furthermore, when this media gets wet and takes on a debris load, airflow will be further restricted. The best approach for protecting this cooling tower would be to use air intake filters which are specifically designed for high volume airflow and use on cooling towers.

Roll filtration significantly reduces air-flow and operational efficiency. Because this unit is high off of the ground, isn't easy to reach. Furthermore, the roll media is a consumable that will continue to cost the operation.

Marley Cooling Tower with roll filter media over the face of the intake opening. Important Note: Roll filter media is not designed for use on cooling towers. It will cause an excessive increase in static pressure even before dirt and debris loads the filter. Furthermore, when roll media becomes saturated with moisture, it further impedes airflow and impacts cooling efficiency. Pulley-Mount Air Intake Filters were installed on these units.
