Nowadays is very popular to use air coolers for low-cost cooling on several kinds of premises. Especially outdoor cooling, like cafeterias and restaurants, in warehouses or garages etc

What is an air cooler?

It is a device that cools the passing air using the cooling fan and the evaporation of water. Evaporative cooling is completely different from other air conditioning and cooling systems.

The whole concept is based on the fact that water will absorb an amount of heat from the air in order to evaporate. The temperature of the passing dry air can be dropped significantly through the phase transition of liquid water to water vapor. This method can cool air using much less energy than air conditioners which use a compressor and freon.

Types of the evaporative air coolers:

Firstly we have the small portable evaporative units. These are suitable for small areas and only a few people to be cooled. Applications are small kitchens, garages for 1 person, small verandas, and other places with just a few occupants/users.

Secondly, we have the more commercial style portable evaporative coolers. These can handle much bigger areas. They provide quite big air flows and sometimes they accept permanent water connections on the supply line. Therefore these units are usually used in restaurants and cafeterias, warehouses or garages. Even big verandas and similar areas.

Finally, we have the ducted type commercial units. These need an air ducting system and have quite a big static pressure capacity. They handle big air flows (more than 10000m3/hr) . We use them in big factories warehouses stadiums and many other huge areas
