ID/OD Enhanced Surface for Improved Boiling Heat Transfer

Turbo-BIII is designed for light hydrocarbon boiling. The tube is configured in variations for both high pressure and low pressure refrigerant applications. 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 because of increased some

surface area and turbulation induced by integral helical ridges on the inside surface. The availability of plain ends and intermediate lands makes Turbo-BIII suitable for shell and tube evaporators.

The ID ridges have been modified to improve the overall heat transfer efficiency of Turbo-BIII over Turbo-BII.
