HEF2E evaporative contact pad coolers are based on an energy-efficient operating principle, the natural principle of evaporation of water by an air stream as it happens in nature. The air passing through a sheet of water partially evaporates it, incorporating the water vapour into its mixture and, at the same time, it cools down as the energy required for evaporation is provided by the air itself.
This Fisair evaporative contact pad is mainly characterised by a stable composition of glass fibre sheets impregnated with additives that give it its absorption capacity without losing its stiffness. In addition, the panel is inorganic, i.e. it does not serve as a food source for bacteria and fungi, making it a highly hygienic panel. Durability and maintenance are also two strong points of these evaporative panels thanks to their structure and the way they are manufactured, with the insertion of sheets under pressure and without the use of any type of glue.
All these characteristics of the panel mean that we are dealing with contact panel evaporative coolers with excellent efficiency, hygiene and maintenance characteristics.
In general, evaporative humidifiers are used wherever the moisture content of a ducted air stream is to be increased, and are very common in data centres, in the pre-cooling of intake air and in paint spray booths. They can also be used in the textile industry, graphic arts, woodworking and other hygroscopic products as well as in the food industry.
