CELdek® Series evaporative cooling pad is used in systems where high efficiency cooling is required. It can be used for many different cooling purposes but is particularly suitable for cooling of livestock buildings and greenhouses when higher air velocity is required.
The green stripe pad consists of specially impregnated and corrugated cellulose paper sheets with different flute angles, that have been bonded together. This unique design yields a cooling pad with high evaporation efficiency while still operating at a very low pressure drop. In addition scaling is kept to a minimum and no water carry-over occurs due to the fact that the water is directed to the air inlet side of the pad.
The impregnation procedure for the cellulose paper ensures a strong self-supporting product, with high absorbance, which is protected against decomposition and rotting and therefore increasing longevity. The water flows down the corrugated surface of the CELdek evaporative cooling pad. Part of the water is evaporated by the warm and dry air that passes through the pad. The rest of the water assists in washing the pad, and is drained back to the pump station through a gutter system. The heat that is needed for the evaporation is taken from the air itself. The air that leaves the pad is therefore cooled and humidified simultaneously without any external energy supply for the evaporation process. This is nature’s own cooling process.
