A TIME TESTED, SIMPLE CONCEPT -

As the name implies, evaporative cooling works by evaporating water in the air stream. In order for this to happen, the water must absorb heat. In the case of evaporative cooling, heat comes from warm or hot outdoor air being supplied to the building. The heat that's absorbed by the water is lost (or given up) by the air, causing the air to become cool.

This principle is best illustrated in a personal way by the chilling effect you feel when you come out of a swimming pool and a breeze blows across your body. The chill you feel is caused by the evaporation process of the water drying quickly from your body.

The same thing happens when you perspire. The feeling of a “cool breeze” is just air flowing over your body evaporating the perspiration. It is Nature's way of keeping you cool during hot weather or physical exertion.

EVAP COOLING - As easy as 1, 2, 3, and 4 & 5!
HERE ARE THE BASICS: Outdoor warm or hot air is drawn to
the evaporative cooler. A pump draws water out of the evap cooler's water reservoir and directs the water onto an evaporative cooling pad, also called “media.” A water distribution header makes sure this water disbursement is consistent and uniform.
The warm or hot air causes some of the water to evaporate from the surface of the media, which makes the air cooler. An air moving device sends this clean, cooled air through ductwork into the building. Temperature is controlled by adjusting thermostats located in the building, just as with
any heating or cooling system.

There is also some minimal maintenance required for optimal performance, and one very easy decision to make: WHAT BRAND OF MEDIA TO USE TO GET THE VERY BEST PERFORMANCE FROM YOUR EVAPORATIVE COOLER.

	Glacier-Cor evap pads (called “media”) are distributed and sold by a national network of highly knowledgeable, independent installers, engineers, and/or manufacturers who will help you design the most efficient, cost effective system for YOUR specific needs. They're nearby, and they're ready to help in any way they can.
	Glacier-Cor quality evap pads are backed by years of research and development. That's because quality pad construction delivers superior cooling efficiency, ease of maintenance, pad durability and longer life. Simply put, Glacier-Cor's quality pads allow MORE AIR to move through the cooler, providing excellent COOLING EFFICIENCY and HIGH AIR VELOCITIES. They CLEAN AIR BETTER, and LAST FIVE TIMES LONGER OR MORE than most pads, which means fewer replacement costs.
	Glacier-Cor quality evap pads are RIGID and SELF-SUPPORTING. They don't require wire grids or framing to keep them in place. This allows you to replace a single pad without removing adjacent pads!
