Evaporative Cooler Airconditioning CELdek Pads 5090 Series

CELdek® 5090 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 evaporative coolers for commercial and domestic use. The pad consists of specially impregnated and corrugated cellulose paper sheets with flute angles (45 deg) that have been bonded together. This unique design yields a cooling pad with high evaporation efficiency while still operating with 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. This is where most of the evaporation takes place. 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 distribution pad constitutes a vital part of a complete system and should always be ordered in combination with CELdek evaporative cooling pads. Placed on top of the cooling pad it ensures a uniform supply of water to the cooling pad and minimises the risk of dry spots.

The evaporative cooling technology

Water is circulated through a pump station and supplied to the top of the cooling pad via a distribution manifold. A distribution pad on the top of the cooling pad ensures an even water distribution. 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 natures own cooling process.
