The Opsinox Triple Flow is a patented combination solution for collective flue, air ventilation and exhaust. It combines several air flows in one chimney, consisting of concentric ducts: the inner duct takes care of wasted gases, the centre duct ensures the supply of fresh air for the combustion boiler, the outer duct regulates the removal of contaminated ventilation air. Due to the specific design of the top element, the different air flows do not influence each other.
Since Opsinox Triple Flow is designed for connection of closed heating boilers, the risks associated to poor combustion is impossible.
