A swamp cooler generated air from the one gotten from the building or environment where it is being used. Swamp coolers keep the air humid as it distributes water while eradicating heat and producing much-needed air. Let us try a little experiment. Try dipping your feet or take a shower without drying off and covering. You can feel the breeze hitting you and leaving you much cooler than the shower itself. This same feeling applies to the cooler.
For a swamp cooler to produce the desired effect, the environment it intends to be used has to be dry and hot. Not cool and wet. The air an evaporator produces is moist and does not dry up quickly because one of the major components of evaporative cooling, is the water which is kept there to keep you cool and refreshed. This method is so fast and effective that even Biblical Pharoah adopted its use in ancient Egypt. Thinking of eradicating the hotness in the air? You should get yourself one of these. It is cost-effective, easy to use and if damaged, the parts are easy to replace. The maintenance cost will not send you running but will surprise you.
Environment and health-wise, a swamp cooler is the safest choice. It is not made with any hazardous chemicals harmful to your health but with water, fan, pump. In this era, where different skin terminal issues are on the rise, it will be best to be well informed of what you allow into your space or breathe in. This is one thing you should not take lightly. It is not useful in a damp environment. You need to put this in mind as well. If an area is damp, the effect of the evaporative cooling cannot be felt due to the humidity.
To enjoy the evaporative cooling for a long time, you need to always clean and change anything that seems to be rusty or not in the best condition. The evaporative cooler helps to expel the humidity in the air and does this with water. All too soon you will notice the air smelling soggy which you will find unpleasant but cleaning will help to prevent this. You also need to ensure that there is a steady and close supply of water to keep the air as cool and fresh as it can be in very hot weather conditions.
