About Twisted Tape

About Twisted Tape

A twisted tape type tube insert is a historically well-known heat transfer enhancement device, with a variety of heat transfer and pressure drop correlations available in the open literature.

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.

Knowledge & Expertise

Knowledge & Expertise

CALGAVIN®’s engineering team has grown its heat transfer knowledge through the innovation and research of its heat transfer enhancement products.

In case you are not sure regarding the final specification of your Twisted Tapes, a vital skill set in modelling thermal and hydraulic ratings of heat exchangers is at the core of what we do. We have the possibility to provide various engineering design services by analysing existing heat exchanger performance, further levels of enhancement possible and CFD (computational fluid dynamics) services, typically used to investigate complex fluid flows around heat exchange equipments, such as vibration, maldistribution or bypass issues.

Further to CALGAVIN’s product offerings, our engineering team is proficient in providing detailed thermal design analysis, including TEMA and API type heat exchanger configurations.
