Benefits of evaporative cooling

  • Clean air that reduces the risk of bacteria and virus
  • No chemicals or refrigerants
  • Low energy consumption
  • Virtually maintenance-free equipment

How does it work

The outdoor hot air is moistened and cooled as it passes through water-soaked filters, then driven indoors at up to 12°C lower temperature. Thus, a constant flow of fresh and natural air is projected, which is introduced clean into the room, eliminating at the same time bad odours, germs and dust. This promotes the constant renewal of air that doesn’t recirculate, generating a healthy environment.

Why Master?

Master evaporative systems adapt to our climate and are an excellent alternative to condition large spaces with low energy costs.

The installation is simple, since it’s sufficient with the positioning of the evaporative equipment on the roof or facade and connect it to a water supply and single-phase electric current. Thanks to its lightness, it doesn’t require cranes or large supporting structures for the installation and commissioning.

Self-management water cleaning system

Thanks to its electronic structure and components (electrovalve, drain valve and level sensors), Master equipment has an automated system for cleaning, emptying and filling water tank.


The evaporative cooler enters in pre-cooling mode for one minute, just before the engine starts to operate, thus ensuring the cooling from the first moment.

Auto mode

With the previous adjustment of the required values of temperature and humidity, this mode allows to operate the equipment autonomously and efficiently by regulating its air flow rate, as well as water levels according to the values (Tº and %RH).

Auto clean

This function allows to set a period of time (hrs.) for the automation of units cleaning. Programmable period of time from 0 to 72hrs. The water drain valve opens allowing its exit and in this way the corresponding cleaning. After one minute the inlet solenoid valve opens, giving rise to a new water inlet in the tank. This self-cleaning mode is adjusted according to the measures and recommendations for prevention and control of Legionellosis.
