Industrial evaporative coolers from 18.140 to 36.678 m3/h 

Evaporative coolers are a natural cooling system that uses water as a cooling element. Its basic operating principle is to suck in the outside air and pass it through some cooling panels moistened with water. Once the air passes through this panel, it cools and increases its humidity.

Once this process has been carried out, the air is propelled inside the premises to be air-conditioned and, based on the appropriate renovations and extraction of air, a comfortable comfort temperature and adequate indoor air quality are achieved for people.

AD BIG PREMIUM evaporative air conditioners, develop an air flow from 18.140 m3/h to 36.678 m3/h with an available pressure at a maximum flow of 100 Pa, its cooling capacity is suitable for premises from 300m2 to 615m2. For larger surfaces more units can be installed.

Its operation is totally ecological due to the fact that no type of refrigerant gas is used in addition to requiring 80% less electrical energy compared to conventional air conditioning equipment.

Another aspect to keep in mind is the constant renewal of indoor air that guarantees eliminating stale environments of odors and fumes.


The installation of evaporative air conditioners consists of a single-phase or three-phase electrical connection depending on the selected model, a mains water connection, support bench, electrical control panel and air diffuser elements or ductwork.

Its maintenance consists of carrying out an annual review of the cooling panels and a general cleaning of the equipment.
