CoolDraft Portable Mister
Cool Draft is an excellent way to cool down during those hot summer days. Ideal for sporting events,
equestrian events, rehab areas in industrial sites and facilities, fire fighters and more.
HEAT STRESS
Heat stress refers to the combination of factors that increase core body temperature: environmental conditions,
clothing and metabolic rate. Our bodies try to achieve a balance between heat gain and heat loss, but when this
balance is compromised the body is unable to function at its optimal level.
The major source of heat gain is the internal heat generated through activity the body undertakes. Of the energy expended
during this activity, only about 25% is translated to mechanical work; the remainder is released as heat in the contracting
muscle. The harder the human body works during a particular activity, the more it generates internal heat.
The major avenue for heat loss is evaporative cooling through sweat. When heat balance is compromised, the body will try
to direct the heat away from the core by increasing blood flow to the skin. At the skin's surface, water secreted
from sweat glands absorbs heat from the skin, changes from a liquid to a vapor and is carried off by the surrounding
air. Because the heat of vaporization is quite high, small amounts of sweat remove relatively large amounts of heat.
Based on this same process, the Cool Draft produces small amounts water (mist) that is propelled onto the skin's surface
from our high-velocity fan. By using a fan, the Cool Draft, dramatically increases the evaporation process, which results
in a 20° to 30° temperature reduction.
