Why is it Called a "Swamp Cooler," Anyway?
The swamps of Louisiana and Florida comprise some of the largest areas of wetlands in the United States. A swamp, essentially, is a flooded forest whose vegetation is primarily trees. Swamps are known for a tranquil outer appearance, and, typically, a very high humidity. Conversely, a MasterCool evaporative cooler is an energy-efficient air conditioner designed for use in very dry climates like the Southwestern United States, with characteristically high summer temperatures and very low humidity.
So, if swamps are humid places, and swamp coolers will not function effectively in humid environments, why do people call evaporative coolers “swamp coolers?”
Simple: evaporative coolers add lots of much-needed humidity into the air. MasterCool evaporative coolers work by blowing a fan across specially-designed saturated rigid media pads. This process results in two very important benefits for homeowners in hot, dry climates. First, the home’s air is cooled, without the use of chemicals and refrigerants. Second, the MasterCool evaporative cooler pumps humidity into the air as it cools, so your home is more comfortable and the air is moist.
Now, if your evaporative cooler starts to smell a little swampy, that’s a problem you need to fix. As with anything that contains water, you want to keep your MasterCool cooler clean. If water stands too long, it can get musty (this is another reason it’s important to ensure that the water is completely drained when you winterize your swamp cooler!). Performing regular maintenance and using a purge pump are two fantastic ways to avoid this. A purge pump periodically flushes the water from the evaporative cooler and replaces it with fresh water. It also prevents scale and mineral buildup in your swamp cooler.
So now you know the link between swamps and evaporative coolers. And while your swamp cooler will make your home comfortable, you can rest assured you’ll never find an alligator in your swamp cooler.
