Kuul Vitality™ evaporative media (a type of rigid evaporative media) is designed to achieve optimal cooling in agricultural environments, including poultry houses, swine, cattle, horticulture, and potato storage. At industry-standard air velocity, Kuul Vitality meets efficiency standards and exceeds pressure drop requirements. Not only do the Kuul evaporative cooler pads last longer, but they help lengthen the life of the whole cooling system by adding less stress to moving components.
The natural process of evaporation involves the active use of water recirculation. In an agricultural setting, fixed systems hold pieces of evaporative media along the outer walls of production buildings. When water is pumped to the top of the Kuul Vitality evaporative media and distributed evenly across the surface, cool air is generated . Gravity pulls the water down and it flows through the evaporative media. The evaporative media absorbs the water and facilitates water molecule evaporation into the air. One interesting fact: more water is pumped to the top of the media than required for the evaporation (or cooling) process for even distribution. The evaporative media is designed so the extra water “washes” or cleans the outer surface of the evaporative media. Remaining water is then returned to the reservoir to be recirculated.
With an understanding of how Kuul Vitality evaporative media works, it’s important to also understand how to maximize the efficiency and longevity of the media. To keep Kuul Vitality evaporative media in tip-top shape, proper maintenance activities are necessary during use. Proactive maintenance is key not only to achieve optimal cooling but also to eliminate any concern for harboring potentially harmful bacteria in the evaporative media.
Good water quality is a necessity for achieving efficient cooling with evaporative media in agricultural environments. The definition of good quality water is having a neutral pH (neither acidic nor basic) and less than 100 ppm of dissolved salts (e.g., calcium, sodium, potassium, etc.). Therefore, we recommend that operators regularly check water quality and analyze for high pH and scaling properties. High pH requires a dosing system for neutralization.
Automatic dosing systems are utilized to protect the evaporative media from scale deposit which includes heavy concentrations of diluted salts, high pH, and algae. Regular maintenance of Kuul Vitality evaporative media includes a shock-dose with household bleach (Sodium Hypochlorite – NaClO) for algae and/or household white vinegar (Acetic Acid – CH3COOH) for lime descaling, if necessary. For bacterial growth control, a solution of household bleach (Sodium Hypochlorite) should be used to ensure the water remains clean and living organisms are unable to grow.
Additionally, a bleed-off or sump/reservoir dumping system is necessary to help control salt concentration and prevent scaling. Automated filtration points and flushing systems are built into most operators’ cooling systems. This allows any dirty sump water to be discharged during the maintenance cycle. This process also ensures that excess, soiled water is regularly dumped.
These dosing and filtration methods help ensure the cleanliness of the overall system. For an easy, at-a-glance overview, here are the top tips to maximize the life of Kuul Vitality evaporative media:
