Details: Heat Recovery Units

The hot air saturated during the drying process, is expelled into the atmosphere from the chimneys and replaced with fresh air; this replacement reduces the temperature inside the dryer until the incoming air is not heated. The heat exchanger has the function of preheating the air that enters through the chimneys exploiting the hot air saturated that comes out.
Consists in a heat exchanger with fins and reversible fans who work in extraction/introduction and that allow a saving of thermal energy from 18 to 25% in addition to a decrease in air pollution.
