Chillcel pads do need to be cleaned or changed about once per year. These pads are to be used with Breezair EXT, EXV, EXH, and EM series evaporative coolers.
Chillcel™ pads are the evaporative medium that is rapidly becoming the standard in the industry because they provide maximum evaporating efficiency. The special design of Chillcel pads ensure that the water flows evenly over the entire surface of the pad and is directed towards the air inlet side the pad where most evaporation occurs. Chillcel pads are essentially self-cleaning, with dust and pollen particles being flushed away by water flowing over the pad and carried to the sump below. This increases the efficiency of the unit as well as prolongs the life of the pad.
