Phoenix Manufacturing sells commercial evaportive coolers under both its Rigid Media brand and its Aspen brand. These coolers are marketed for industrial, institutional and agricultural settings.
Traditional cooling systems work by letting heat dissipate from compressed refrigerant, so they are typically efficient in all environments. Evaporative cooling, on the other hand, depends on water evaporating. As a result, evaporative cooling in less efficient in humid environments where water takes longer to evaporate. In dry areas, however, evaporative cooling can provide efficient cooling, especially in large warehouses and commercial environments. Evaporative cooling also increases the humidity in the structure being cooled, so the building owner can avoid having to purchase separate humidifiers.
