Two Stage Evaporative Cooling System for 100% fresh and healthy air
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.
