Evaporative coolers
Master evaporative coolers cool the air using a simple natural process – the evaporating water decreases the temperature of the air. A pump takes the water from a tank and dampens a large pad made of natural cellulose. A powerful ventilator aspires air through the filter. The water evaporates from the filter and decreases the temperature of the air by several degrees. The fresh and clean air flows into the room and cools it down.

How does it work
The heart of the evaporative cooling system is the cooling pad where the water evaporates and the air passing through the pads is cooled. Evaporative cooling pads are manufactured from fluted cellulose sheets that are glued together. The material is chemically impregnated with special compounds to prevent rot and ensure a long service life and easy maintenance.
Evaporative cooling and humidity
A given volume of air at a certain temperature and pressure is capable of absorbing and holding a certain amount of water vapour. If that volume of air contains 50% of the moisture it is capable of holding, we say it is at 50% relative humidity.
The hotter the day, the drier the air, the more cooling can be done by means of evaporation. In other words, the cooling effect is best when you need it most.
Our evaporative coolers are developed to work well in high-humidity environments too, however, and will remain much more efficient than a simple fan that just circulates warm air.
Our coolers will increase humidity by 2 to 5%, depending on temperature and humidity in the environment you want to cool. The slight increase is not noticeable in ventilated areas where the air produced by the unit is exhausted.
