ID/OD Enhanced Surface for Improved Boiling Heat Transfer

Turbo-ELP is designed for boiling of low pressure refrigerants. The integral helical fins on the outside of the tube are modified to enhance the initiation of nucleate boiling sites, thus improving the over all heat transfer coefficient. The inside heat transfer coefficient is improved over smooth bore products 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-ELP suitable for shell and tube evaporators.

The external configuration and the ID ridges have been modified in such a way to match the Turbo-BIII LP performance.
