About Twisted Tape

Twisted tape geometries divide the flow within the tube, creating spiral flow paths resulting in higher velocity at the tube wall. For many conditions they also induce swirl flow which increases local velocities and promotes mixing.

Nevertheless, they have lower effectiveness than hiTRAN® Thermal Systems across the whole flow range but can be suitable options where available pressure drop is limited.

As performance correlations are in the public domain and not owned by CALGAVIN®, thermal performance guarantee will not be provided for this enhancement product.
