b!klimax+ Twin Copper is a high-output system for ceiling heating and cooling with hanging structure. It consists of metal tiles with sound absorbing properties, which are installed by means of M6 threaded rods or steel rods. b!klimax+ Twin Copper radiant panels contain copper coils of Ø 12 mm and are characterized by the capacity to spread and absorb the heat on both sides, which implies higher thermal performance in winter and in summer, above all in commercial buildings with tall rooms and very high heat loss and heat gain.
