Among other things, Menerga develops products that are based on the efficient, natural principle of indirect evaporative cooling. This means that you make use of the physical effect that evaporating water extracts heat from the air and that the air is thus cooled. The exhaust air is humidified where it enters the countercurrent heat exchanger. With evaporative cooling, the air temperature can be lowered by up to 14 K, without having to add any energy for cooling.
