This pad is a high efficiency evaporative cooling media. It is manufactured with high absorption cellulose Kraft paper, treated with advanced resins and additives to achieve long-lasting and low maintenance. <br><br> High performance heavy virgin Kraft paper, treated with wetting additives and anti-rot agents. Plus, high-quality adhesives and rigidifying agents for increased resistance make a top-quality cooling pad. <br><br> HOW does an evaporative Cooling system work? When passing hot dry air through thin layer of water film, water uses heat from the incoming air to evaporate so the air coming out is cooler and wetter, causing an initial drop in temperature of up to 15 degrees depending on the temperature and humidity present in the air. <br><br> WHERE you can use it? As we have seen the evaporative cooling process depends on water and dry air to achieve optimal cooling conditions, so the operation of evaporative cooling equipment is more efficient in the desert and dry environments. In desert areas of our country evaporative equipment is used in homes, offices, shopping malls, industrial plants, every where. <br><br> We also carry assembled water walls of different sizes that’s ready to be installed on your greenhouse or other facility. Because of large size, freight shipping is needed. We are located in Lancaster, California. Contact us to discuss your needs.
