Turbo E tube
Far a wide range of demanding evaporator applications the
integral helical fins on the outside ot the tube are modified to
enhance the initiation at nucleate boing sites improving over
all heat transfericcefticient.
The inside heat transfer coefficient is improved because ot
increased surface area and turbulation induced by integral
helical ridges on the inside surface.
