What Is a Swamp Cooler?

Swamp coolers also known as Evaporative Coolers  are a type of cooling device used in warehouses, factories, and other places to reduce high heat temperatures. Generally, swamp coolers have also been known to be called desert coolers or wet-air coolers. They work by sweeping hot circulating air through a wet media pad and converting it into cool air being pushed into the facility in a circulating function.   

Evolution of Evaporative Coolers

Evaporative coolers use the same science as sweating for most terrestrial beings and plants. The mechanism is simple, but we all do it differently. Going back as far as 6,000 years.

Plants employ a form of evaporative cooling known as transpiration. On the leaves of plants, tiny pores allow water to be drawn from the soil to the leaf's surface. This water evaporates and cools the plant. Plants have mechanisms to increase the likelihood of this phenomenon, including increasing their leaves and increasing themselves higher from the ground until they suffer too much evaporation and wilt (dry up).

Dogs' panting helps the blood to circulate from their nose, throat, and lungs to the lining of their brains, allowing them to cool down. Their unique blood vessels act as heat exchangers between the inside of their noses and brains, allowing the latter to be cooler than the rest of the body.

Cats also use a physical mechanism to regulate their temperature. While the primary reason for licking their fur is for cleansing, the moisture on a cat's fur as it grooms itself evaporates, anchoring its temperature. 

Other animals, like pigs, often wallow or roll to coat themselves in mud, then let the water from the mud evaporate, cooling themselves.


Swamp Coolers: The Early Signs of a Soon-to-Be Major Trend

It can be challenging to pinpoint when humans started using evaporative cooling. From the earliest periods of human history, people have included fountains in construction. This is merely an opening way for evaporative cooling. As air splashes up with water, some moisture evaporates, keeping the air cool. The water exposed to the air in bubbles or spray has a more pronounced evaporation effect than misters, even though the two are somewhat related. 

It is a known fact that ancient Egyptians hung wet blankets or reeds by their doors for air to cool before entering their houses.

Patenting & Powering Swamp Coolers

The swamp coolers we now typically refer to as Evaporative Coolers  were invented quite early in our century. Numerous people have already tried to create these coolers, but today, they function differently than ever since they were patented. These coolers utilized an evaporative medium, like wood wool. An evaporative medium works just like cloths surrounding the water jug; it increases the surface area for the fluid to adhere to and water evaporation. This improves the cooler's cooling capabilities. 

One noteworthy use of swamp coolers in the 20th century was automobile coolers. These were containers that were attached to the outside of a vehicle. They were filled with water and contained an evaporative medium. As the vehicle started, the cool air forced water through the tubing, which evaporated and cooled the air.


Concluding history, swamp coolers are now widely used devices, especially in large industries. They are great for cooling down your work facilities no matter the size. For all demands and needs you can guarantee a Portable Evaporative Cooler can provide the comfort you are looking for.
