Evaporative cooling has been around much longer than central air conditioning and has proven to be just as good at cooling in arid parts of the country. The technology works by the same process our bodies use to control temperature—perspiration. As we sweat and our perspiration evaporates, our skin feels cooler. Swamp coolers use hot air to absorb water, and the hotter the air, the better the cooling. Warm air from outside is drawn into a fan and pushed through moistened pads. The air is then vented into a room or through ductwork. Pads are made of shaved wood (cedar...

There is wide array of industrial evaporative cooling units (or swamp coolers) on the market today. Swamp coolers are becoming more and more popular, especially when business owners and industry professionals recognize the value of efficient, low-cost cooling with low environmental impact. They are often used in commercial kitchens, dry cleaning facilities, industrial plants, warehouse/loading docks, construction, sports arenas, garages, and animal facilities to control heat. Adequate cooling is crucial in commercial and industrial settings where workers are exposed to heat. High temperatures can make workers feel uncomfortable, and high heat can be be dangerous. Extreme heat can cause a...

Evaporative coolers (or swamp coolers) can help homeowners, business owners, and industry professionals by keeping building occupants cool. Evaporative cooling increases humidity, improving the breathability of the air. It offers cooling and air filtration in one unit, as it pushes air through a layer of padding. The padding acts as a filter, removing certain contaminants from the air—especially those that can cause allergies. Swamp coolers also filter odors, making indoor work and leisure more enjoyable. Evaporative cooling technology can expose building occupants to fresh air throughout the day. Unlike central air conditioning units, evaporative coolers don’t require a building to...

Evaporative coolers (also known as swamp coolers) can lower the temperature of outdoor air by as much as 30 degrees. Evaporative technology cools without the hassle or high costs of central air conditioning, but there are some things to know know before you buy: Evaporative coolers cost half the price of air conditioners that cool the same size area. Some municipalities and government entities offer rebates for use of evaporative coolers. An evaporative cooler requires a constant supply of water and a 120-volt power supply to operate. No Freon is required in evaporative cooling. Swamp coolers create a complete air...

Exhaust fans play a major role in air quality and temperature controls for residential, commercial, and industrial applications. They work by drawing stale air out of homes and buildings to be replaced with fresh, outdoor air to meet HVAC industry-recommended air quality standards. Ventilation exhaust fans can help provide a healthful living environment by removing toxic gases, chemicals, and odors. Mold and mildew caused by heat and moisture (particularly in bathrooms, kitchens, and other areas that generate heat and moisture) can cause health problems and compromise the structural integrity of a home or building. Similarly, areas that generate smoke, chemicals,...
