INDUSTRIAL EVAPORATIVE COOLERS
Evaporative cooling is a process in which air is cooled by using the heat in the air to evaporate the water. The temperature reduction depends on the ambient condi-tions. Ideally the temperature reduction of 10o to 20o C can be achieved by passing the hot air through the cooling pads.
An evaporative cooler basically consists of a blower and water wetted pads. Fresh ambient air is cooled by passing it through the pads. The air is first passed through the pre-filter before being passed
through the cooling pads. The cooling pads cools the air and also act as secondary air filters. The fine dust trapped on their wet surface is washeddown into the sump, where it is contained.
