Cooling towers are defined as any open water recirculation device that uses fans or natural draft to draw or force air to contact and cool water by evaporation.
Evaporative coolers are cooling devices that use the evaporation of water into the air to cool the air temperature. They are sometimes called air coolers, desert coolers or swamp coolers.
Industrial cooling systems and industrial cooling equipment includes air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers; ducts and/or pipes; and other devices for removing heat from a system that contains a heat source.
