Kubota has named this new technology MERT (Mixing Element Radiant Tube). MERT is a centrifugally cast tube in Kubota's high quality alloy with a spiral mixing element on the inside surface. In 1996, the first MERT has been installed in a commercial ethylene cracking furnace. Since then, Slit-MERT and X-MERT have been developed. MERaT series has been applied to over 300 furnaces through the world.
