General Evaporative Cooling Media Maintenance Guidelines* (*Always follow all manufacturer's advice on media maintenance)
Maintenance Rules and Information:
Simple Suggestions to Maximize the Performance and Life Expectancy of your Evaporative Cooling and Humidification Media
¨ Drying out the pads once every 24 hours helps to reduce microbial growth on the pads. ¨ Since the water evaporated from the pads is pure water vapor, minerals in the water source remain in the unit’s water recirculation system. Reduce possible scale build up on the pads by minimizing minerals in the sump – several methods are available to accomplish this task: constant bleed-off system, daily complete sump dump cycle (this removes both mineral build up and debris form sump), water treatment is available to maintain higher cycles of concentration of minerals if other methods are not available. ¨ Minimize use of oxidizing biocides (chlorine and bromine) these degrade organic resins used in the manufacturing of the pads. ¨ If chemical water treatment is required, quaternary amines can be utilized in significantly higher dosages without damage to the pads. Provide proper support under the pads to avoid media sagging and fall-out of the support system. Often this is accomplished by the addition of expanded stainless steel to support rails at the base of the pads
¨ Maintain the water distribution system to eliminate dry streaks on the pads – these dry streaks significantly reduce performance and reduce the pad’s life expectancy. ¨ Minimize the cycles of turning the water circulation pump on and off. Frequent on and off cycles will lead to scale build up and reduce the life of the pads. ¨ Maintain the pH of the recirculation water in the system between 6 and 8, this will minimize scale as well as minimize the degradation of the pad’s organic resins. ¨ Avoid direct sun light on the pads and sump area to minimize microbial growth. ¨ Pre filter the inlet air to the pads to eliminate or reduce the amount of dust, leaves, etc to the pads. Since the pads work as an air washer, debris that enters the air inlet of the pads may be washed from the air stream and into the sump – thus creating a high maintenance sump cleaning program. ¨ Quarterly cleaning and disinfection of the sump will minimize possible microbial growth sources. ¨ Maintain a clean, clog-free water distribution header system operating at design water flow across the entire width of the pads.
