France/Finland: Saint-Gobain has collaborated with Finland-based measurement equipment supplier Vaisala to develop dew point monitoring solutions that reduce the energy used in drying gypsum wallboard. Saint-Gobain already uses electric drying systems at two of its plants.
Saint-Gobain drying process team leader Jérôme Cantonnet said "These conditions present a significant challenge for sensors. We tried a number of different humidity and temperature sensor suppliers in the early days and found their products to be insufficiently accurate."
