Vipertex® enhanced surfaces are flow optimized process surfaces that increase heat transfer through a combination of factors that include: increasing fluid turbulence, secondary flow development, disruption of the thermal boundary layer and increasing the heat transfer surface area. In addition to heat transfer enhancement, the fouling rate of Vipertube was much less than the rate of smooth tubes; additionally the total amount of fouling over a given time period was also less. This reduction in the rate of fouling is the result of secondary flow patterns that form as a result of the patented Vipertex® surface design. These secondary flows circulate near the tube surface and clean it, preventing the buildup of materials.
