Evaporative Air Coolers

Portable Evaporative Air Coolers 

Evaporative cooling is a method of converting hot air into a cool breeze using the process of evaporating water. It is similar to the cool refreshing effect you feel when you immediately step out of a pool.

Evaporative coolers utilize the natural process of water evaporation along with an air-moving system to create effective cooling. Fresh outside air is pulled through wetted filters that cool the air through water evaporation. A blower wheel then circulates the cool air throughout a room, home, or business.

    Cooler Temperatures - More Comfort!
    Evaporative air-cooling creates cooler temperatures a number of ways:

        • It lowers actual temperature and will nearly always deliver cooler air under a wide variety of typical summertime climatic conditions.
        • It lowers effective temperature - the temperature you feel - by at least an additional 4º to 6º. In some cases, the temperature will be lowered more, depending on relative humidity. The rapid motion of cool air increases skin surface evaporation resulting in body heat loss.
        • It reduces radiated heat. The constant flow of cool air absorbs heat from all exposed surfaces and results in a reduction of the heat radiated to the human body.

Evaporative coolers will add humidity to the air and performs best in dry climate conditions, they are widely used and most effective in arid, desert regions such as the southwestern USA. Evaporative coolers are also used to cool green houses in any type of climate condition and is ideal because it will add humidity to the plant environment.

Advantages:
Less costly to use
Easy to install
Will add humidity to a dry climate area

Disadvantages:
Not recommended for high humidity areas such as the south east USA
Requires a constant supply of water
Can create odors if not kept properly cleaned
