1.7 Applications
The ROOF COOLER is an evaporative cooler for large rooms, such as workshops, industrial
departments, commercial and civil buildings, agricultural and livestock premises, etc., which works
based on the principle of adiabatic cooling. Warm air is drawn in from outside, flows across the high-
efficiency evaporative panels and comes into contact with the water flowing through the panels from top
to bottom. The evaporation removes heat from the air and naturally lowers its temperature. The fresh
air is then conveyed and distributed to the space to be cooled through a duct. The cooling capacity
depends on the temperature, room humidity and air distribution.
As well as a cooler, the unit can also be used as a humidifier for large room volumes, in industrial, civil,
agricultural and livestock applications, or as a simple ventilator, when cooling or humidification is not
necessary.
The materials used guarantee reliability and durability, even in the most critical environments.
This machine must only be used for the purpose
for which it was designed: "Adiabatic cooling/humidification". All
other uses are considered improper and therefore potentially
dangerous
.
