Corrugated and dimpled tube heat exchanger [c&dt] is perhaps the most exciting advancement in heat transfer technology. It offers shell and tube heat exchangers with special operating features over the conventional shell and tube heat exchanger. The most important feature of c&dt is the corrugated tube which induces turbulence in both flows [product and service] at lower velocities. This turbulence ensures uniform temperature distribution and results in improved heat transfer co-efficients by up to 60% over smooth tube unit. User advantages are: compact tubular heat exchanger; longer running time as the turbulent flow reduces fouling; ideal for high temperature and high pressure applications; very low maintenance costs, minimum spares requirement;uniform thermal processing;high response to cleaning-in-place; and higher coefficients result in closer temperature approaches between product and service fluids.
