Ag Evaporative Cooling Systems Compared - Part 2, Pad and Fasteners

Most commercial broiler farms utilize an evaporative system to provide cooling during hot weather. Although there is no substitute for regular maintenance and cleaning, choosing the right system can reduce repairs. In part 2, we compare pad, distribution and fasteners of Hog Slat’s Evap System against competitive brands.

The Evap System features a large capacity spray bar with more holes per running foot to reduce pad streaking. Attaching the sections with bell connectors eliminates the dry areas in the pad common with coupled spray bars.

Pad saturation is enhanced because the top deflector angles the water flow to the outside of the pad. By directing the water to the outside surface, the water is pulled through the pad wetting the full 6″ width. Designs with the water deposited in the middle of the pad may not utilize the entire pad.

The Hog Slat system features three robust, easy-to-remove, Tri-Knob nuts with brass inserts to hold each aluminum pad retainer in place. Each section of the deflector and pad retainer is joined with connector clips to prevent dips or bows in the installation.

Manufactured from heavyweight Saturation Grade Kraft paper for high absorption rate and glued with proprietary resins mixed with additives for fire resistance and fungus protection. H2PAD pad is then triple cured in precisely controlled ovens and cut to exact lengths. 3/4″ ProTec edging extends pad life by protecting against UV and mechanical damage. Additional ProTec coating is available on the pad bottoms to guard against premature damage.
