An evaporative air cooler (also called water cooler, swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by employing water's largeenthalpy of vaporization.The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants.

The cooling potential for evaporative cooling is dependent on the wet bulb depression, the difference betweendry-bulb temperature and wet-bulb temperature. In arid climates, evaporative cooling can reduce energy consumption and total equipment for conditioning as an alternative to compressor-based cooling. In climates not considered arid, indirect evaporative cooling can still take advantage of the evaporative cooling process without increasing humidity. Passive evaporative cooling strategies offer the same benefits of mechanical evaporative cooling systems without the complexity of equipment and ductwork.

Q: Are evaporative coolers more suitable for specific climates?

A: Evaporative cooling is especially well suited where the air is hot and hu midity is low. However, in higher humidity areas there are many proven cost effective uses for evaporative cooling that make it the right choice. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses, spot cooling (loading docks, warehouses, factories, construction sites, athletic events, workshops, garages, and kennels) and confinement farming (poultry ranches, hog, and dairy)

Q: What advantages does evaporative cooling have compared to refrigerated cooling systems?

A: Evaporative cooling will provide substantial energy savings over refrigerated air units. The simplicity of the design allows low maintenance requirements. The evaporative cooler will provide fresh, filtered air. The outside air that has been cooled will blow the stale inside air out. With the substantial savings on energy and the air constantly changing, the industrial / commercial evaporative cooler is ideally suited for area cooling or spot cooling in factories, laundries, churches, schools, agri-businesses, restaurants and many other applications.

Q: How often do I clean my pads?

A: Pads should be cleaned at least once a season prior to storing for the winter . In hard water areas, cleaning may be required more frequently. Periodic, visual examination is required. Remove the back or top of the cooler following the instructions in the operating manual. Look at the pads. If they show signs of heavy mineral deposits they will need to be cleaned.

Note: Be sure to unplug the unit before you access the inside.

Q: How do I clean my pads?

A: Remove the back or top of the unit following the instructions in the operating manual. Note: Be sure to unplug the cooler before you access the inside of the unit. Remove the pad from the unit or back panel. Rinse the pad with fresh water using a hose or soaking the pad in a tub until the mineral deposits disappear. You may want to change the tub water occasionally to accelerate the cleaning process. Allow the pad to sun dry. Reattach the pad to the cooler back panel or reinstall inside the cooler. Replace the top or back panel on the cooler.

Q: How often should the pads be replaced?

A: Pads should be changed when they no longer cool as effectively as they did when new. This generally happens when mineral deposits on the pads become so heavy that the water running over them during operation cannot be absorbed. If a pad is properly cleaned and maintained, its life can be three to five years or more. But, we advise customer replace the pad every 2 or 3 years to keep the best cooling efficiency.

Q: Why is the cooler not cooling like I expect?

A: First check and make sure that the water tank is full. The water indicator located on the top or face of the unit should be in the full position.

Evaporative cooling is humidity sensitivity ? the higher the humidity of the air being cooled the less the cooler will be able to lower the temperature. If the unit is not cooling properly check the humidity of the outside air being drawn into the unit. If it is over 55%, the unit is producing the lowest temperature that an evaporative cooler of its size and type can produce.

If the outside humidity is low then the unit may not be set up properly. Windows and doors must be left open and cross ventilation provided for. Please review the quick guide included with each unit for more detailed instructions.

Q: Why do you have to have windows and doors open?

A: Unlike refrigerated air conditioning, to enable an evaporative cooler to perform to its maximum potential, it is necessary that it draw warm, dry outside air across the water saturated pads. This causes evaporation to take place and that results in a drop in air temperatures. However, this cooling process increases the humidity of the air that enters the room. The increase in humidity necessitates that a window or door on the other side of the room be left open to allow the moist, cool air to exit. If the cooler were allowed to operate in a closed room, it would be able to draw only the air inside the room, air that is already saturated with humidity. If allowed to persist the temperature and the humidity levels in the room would quickly rise to an uncomfortable level.

Following the quick guide set up instructions included with each unit is critical for getting the a maximum performance from your evaporative cooler.

Q: How much water do I put in?

A: The amount of water required will vary depending on the size of the unit you own. To help determine the correct level, each evaporative cooler is equipped with a water level indicator. It can be found on bottom sump of the unit. Add water until the indicator shoes that the water reservoir is filled. Water will leak from the unit if it is overfilled.

Q: At start-up, the air has a slight odor?

A: Occasionally an evaporative cooler may give off a slight odor when first put into use. To eliminate this odor, run the unit for an hour, drain all the water from the tank and add fresh water. If odor persists repeat the above procedure until it is eliminated.

Q: How often do I have to fill the mobile unit?

A: The length of time will vary depending on the dryness of the air and the speed at which the cooler is running. Typically water supplied should last from for one day, or half day, because we design the tank for 8 hours use or 4 hours consumption.

Q: Can the pump run dry?

A: The unit can be safely run without water in the tank. It will cause no harm to the cooler or the water pump. Never choose cooler with submersible pump that usually used in glass fish bowl. It will burn while lack of water and cause danger.
