Evaporative Coolers

Description

The Hessaire® Evaporative Cooler is a natural way to condition the atmosphere. It cools by combining water

evaporation with aire movement, through carefully designed and manufactured equipment, providing maxi-

mum eciency and safety. This air conditioning system, in addition to being economical, gives more benets

than other air conditioning systems for homes and businesses. The system does not use refrigerants or compres-

sors; it cools by simply moving air through moist lters. Air temperature drops when a liquid, in this case water,

transforms into gas. Humidity is not perceived, since the air in the room is renewed approximately every two

minutes, providing a comfortable cooling eect. Continuous air circulation is a vital aspect of the cooling process

in this equipment, and gives it a distinct advantage over air conditioning by refrigeration.

Unpacking

Handle product carefully and check the packing list to account for all items. Visually inspect for shipping damage.

If damaged, immediately le a claim with the carrier.
