Specialized in Refrigeration and Air Conditioning

Turbo-CDI is designed for light hydrocarbon condensing.  The integral helical fins on the outside of the tube are modified to enhance the condensing heat transfer coefficient.  The inside heat transfer coefficient is improved because of increased surface area and turbulation induced by integral helical ridges on the inside surface.

The availability of plain ends and intermediate lands makes Turbo-CDI especially suitable for shell and tube condensers.

The increased ID ridge count improves the overall heat transfer efficiency of Turbo-CDI over Turbo-C, while slightly increasing the ID pressure drop.
