INDIRECT EVAPORATIVE COOLING

In Two Stage Evaporative Cooling system, the first stage is Indirect Evaporative cooling. In Indirect Evaporative cooling stage(IEC) the water and hot air travel in different channels. Water and hot air do not come in direct contact with each other. This is why it is called Indirect Evaporative cooling. Dual-stage combined is also called the Indirect Direct Evaporative Cooling system. The heat exchanger used is a cross-flow, plate-type polymeric exchanger. Warm, primary air flows in enclosed channels. It gives up its heat to water films flowing down the other side of the polymeric plates. A secondary air stream flowing in the direction opposite to the water evaporates water before it is exhausted outside. Thus, the primary air is cooled without any moisture addition. In Two-stage Evaporative cooling, no free moisture is added to the incoming air and because of this fact it is sometimes called dry evaporative cooling. Two-stage Evaporative coolers are also known as Indirect Direct Evaporative Cooler. Evapoler has used this two-stage evaporative system in replacement of air conditioner for comfort cooling large industrial spaces where air conditioning is not feasible. All food processing applications, Industrial Kitchens where positive pressure is a concern and need a large volume of cool & fresh air, Indirect Direct Evaporative cooling system is the best cooling option.
