A large rotary heat exchanger wheel in a steel casing, topped by a "EUROVENT CERTIFIED PERFORMANCE" sign, faces the aisle on the Kastt stand. A moss wall, wood panelling and a forest graphic frame the exhibit, and the pale green wall behind reads "KASTT. ENERGY FOR NEW SOLUTIONS" and "A subsidiary of VINCI".
