Evaporative air cooling is natural cooling similar to wind flowing across a lake. They deliver 100% fresh filtered cool air at much lower cost than a refrigerated air conditioner making evaporative air coolers the most viable & economic option for cooling large & open areas. Evaporative air coolers also eliminate the need to shut doors and windows instead when doors & windows are left open.
An Evaporative Cooler works on the principle of evaporation of water. Each cooler contains specifically designed large cooling pads. As the hot air passes through the wet pads, water absorbs some of the heat as it evaporates. The perfectly cooled fresh air is then delivered into the building.
Alongside the benefits of low-cost cooling, evaporative can also be used to humidify dry air and can be used as a humidification device, the windows and doors should be closed. This allows the humidified air to accumulate.
