Cooling pad with a high evaporation efficiency
This unique design yields a cooling pad with a 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 placed on top of the cooling pad it ensures a uniform supply of the water to the cooling pad and minimises the risk of dry spots.
Water is circulated via a pump station and supplied to the top of the cooling. A distribution pad on the top of the cooling pad ensures an even water distribution. The water flows down the corrugated surface of the EVAP-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. 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.
