Frequently Asked Questions

• Evaporative air coolers are excellent for health
• They supply 100% fresh, filtered air into your building that is not recirculated, improving Indoor Air Quality (IAQ) of the space, supporting customer and staff well-being
• They remove unhealthy pollution from your indoor environment
• They provide basic moisture that the human body needs
• They remove static electricity; they can assist in reducing the effects of illnesses such as asthma.

Yes, evaporative coolers are the same as evaporative air conditioners. The words have the same meaning with regards to types of air conditioning. Evaporative air conditioners are also known as adiabatic coolers and in some regions are colloquially known as swamp coolers or desert coolers. Seeley International is world-leading in the evaporative cooling market, designing and manufacturing premium quality evaporative cooling solutions that are durable, guaranteed and ultra-efficient.

Depending on the technology you will be choosing, our local partner (or Seeley International) will elaborate the estimated count of coolers needed for your specific situation. We want to make sure your space is correctly sized with the right number of coolers, so do not hesitate to get in touch with us.

It is extremely important to properly manage water quality to extend the life of the pads and reduce maintenance. Seeley International evaporative air conditioners have a bleed feature that discharges a small amount of water to reduce the salt concentration in the tank reservoir. If fitted, the automatic Water Management System constantly checks water quality with a probe that sends a signal back to the electronic module, which then drains some water that has higher salt concentration and replaces it with fresh water.

A high inlet water temperature does not have a marked effect on the supply temperature of Seeley International’s evaporative air conditioners.

In an evaporative air conditioner (cooler) a pump circulates water from the reservoir on to a cooling pad, to fully saturate it. A fan draws air from outside the unit through the moistened evaporative cooler pad. As it passes through the evaporative cooler pads the air is cooled by evaporation.

Yes. Outdoor areas have no walls to contain the cool air. These spaces would be impossible to cool using refrigerated air conditioning because this relies on recirculating and reusing air from a sealed area. Evaporative air conditioners can easily supply a flow of fresh and cool air to open and semi open areas since the air is exhausted naturally.

Refrigerated air conditioners tend to deliver less cooling as ambient temperatures rise, and  eventually will end up failing altogether in extreme temperatures. The way evaporative air conditioning technology works, it continues to cool as temperatures rise. Evaporative coolers performance also increases as temperatures rise – again, in complete contrast to refrigerated systems.

In most cases evaporative air coolers marginally increase humidity, keeping in mind that temperature has also dropped significantly. It is the combination of temperature, humidity and airflow that creates human comfort and evaporative air conditioners are used widely around the world because they can create comfortable conditions. For example, 80% humidity and 30°C is very uncomfortable, but 80% humidity and 16°C is very comfortable. Comfort is also improved by increasing air velocity in hot conditions and evaporative air conditioners create sufficient air movement to minimize the effects of humidity.

Often, in large industrial buildings, there are locations inside the plant where heat is concentrated for a variety of reasons. It might be a furnace operation, part of a painting process, concentration of people or a cluster of injection moulding machines. In all these cases, when you do not need to air condition the whole building, you only need that particular spot to be more comfortable. Spot cooling with an evaporative cooler can dramatically improve the conditions in a set location and the productivity of the plant; costing much less than refrigerated air conditioning.

Air inside the building collects heat, moisture and impurities and must be exhausted. The evaporative air conditioner (cooler) provides 100% outside air which must be relieved from the building. If the building is sealed, the effectiveness of the cooler(s) will be reduced. Mechanical extraction or even just leaving some doors or windows open helps remove unhealthy air from the indoor environment by supplying 100% fresh, filtered air. For this reason, evaporative air conditioners (coolers) are much healthier than refrigerated air conditioning.

There are several options with ducted evaporative air conditioning, the most common being on the roof with simple “drop ducts” to deliver the air where you need it. Because evaporative cooling moves more air than refrigerated air conditioning, it’s usually easier to place cooling where you need it without extensive ductwork. You can contact one of our Commercial team by clicking here for further information and advice on system design.

Properly maintained evaporative air conditioners (coolers) will not transmit the bacteria because they do not produce aerosols. Evaporative air conditioners should not be confused with cooling towers or evaporative condensers, which involve different technology. Evaporative air conditioner water temperatures are much lower which prohibits the growth of legionella.

Secondly, in a high quality evaporative air conditioner (cooler), water is drained from the unit when it is not being used, so there is no standing water that could rise to ambient temperature. Above all, well designed evaporative air conditioners do not produce aerosols, meaning that even if bacteria were present in the cooler, there is still no mechanism that could transfer the bacteria to humans. Moreover, there are no recorded cases of this technology causing Legionnaires’ disease and research indicates transmission of the bacteria is not possible by the evaporative cooling method.

Yes. With the MagIQtouch controller you can control up to 60 coolers and set up with a 7-day program: program mode divides each day into four different time periods. You decide how you want your system to work. With the MagIQcool controller, you can decide how long you want the evaporative cooler to delay power on and off.

Evaporative air conditioning prices vary depending on the size of building, location and requirements. You need to speak with one of our sales engineers or local partner to get an accurate price for evaporative air conditioning. We can direct you to your nearest contractor: contact us by clicking here.

Yes. With no recirculated air (as from traditional refrigerated systems), evaporative cooling is the best solution for industrial plants, especially in production and packaging areas. Keeping doors or windows open (or using an exhaust fan), the fumes, germs, CO₂ and odors are drawn outside while the cooler brings in 100% fresh air.

Yes, it is possible. The water drained from your evaporative air conditioner can be used for industrial or agricultural purposes, for example to fill the firefighting tank or for irrigation. Check with your local authority for waste water regulations in your area.

Seasonal maintenance services must be performed before and after the summer season. For evaporative coolers working for more than 12 hours per day all-year-around, it is necessary to follow the service intervals and instructions outlined in the Owner’s Manual. The frequency of cleaning depends on water quality used and operating conditions. For standard scheduled servicing and technical advice you can contact us by clicking here.
