Summary
The Boortmalt malting plant’s solar thermal plant in Issoudun is one of the largest installations of its kind in Europe for an industrial site. It provides renewable and sustainable heat to this industrial site using solar thermal collectors that produce hot water, stored in a tank to ensure a continuous heat supply, day and night. This heat is then used to preheat the air for the barley drying process, limiting gas use and optimizing the share of renewable energy.
Solar thermal is a reliable source of heat, and the plant offers economic advantages compared to the price of gas, as well as environmental benefits by reducing our CO2 emissions, all without making any noise.
