WHITE PAPER
EVAPORATIVE HUMIDIFICATION
AND COOLING FOR ALL CLIMATES
WHY HUMIDIFY AND WHY CONSIDER
EVAPORATIVE TECHNOLOGY?
Facility managers, owners and operators humidify their buildings for many reasons
the most common being the health of the people in the building and to protect equipment or products from dry air. Of course, humidification has a cost to operate.
Evaporative humidification and cooling, regardless of the climate, can be the most cost-effective way to keep your building healthy, comfortable, and profitable.
WHAT IS EVAPORATIVE HUMIDIFICATION
AND COOLING?
Humidification is simply adding water to the air of a building for health, comfort,
preservation, or process. One common way to humidify is to boil water and add the steam to the air, which is known as steam humidification. In comparison, evaporative humidification draws water into the air through the natural effect of evaporation
(hence the name). Hanging laundry to dry and using hair dryers are common examples of this. Evaporation also causes the air to cool down, like the cool breeze off a lake or the cooler air near a waterfall.

The primary methods for evaporative humidification and cooling are
High Pressure nozzles and Wetted Media Systems. High Pressure simply uses a pump to pressurize clean water and push it through small nozzles to atomize the water into the air handler or space. Wetted Media
Systems distribute water over a pad in the air handler, and the airflow over the wetted media causes evaporation. Other options include ultrasonic and pressurized air systems.
WHY CHOOSE EVAPORATIVE
HUMIDIFICATION AND COOLING?
As discussed above, humidification is important for your commercial or industrial building. Whether you need to protect your employees, or your manufacturing line needs to operate at peak efficiency, choosing the correct humidification for your application can make order-ofmagnitude differences in your annual utility costs. And this is true from the deserts of California through the frigid winters in Minneapolis.
