The development of Corrugated Tubes is perhaps the most exciting advance in heat transfer technology. It has long been accepted that if you agitate a hot liquid it cools faster since the shaking produces turbulence that enhances the heat transfer from the liquid to the air. HRS has developed heat transfer enhancing corrugated tubes to achieve a similar result by creating turbulence in the media without using any mechanical shaking. A new style of corrugated tube is boosting heat transfer multifold at low Reynolds number with minimum increase in pressure loss.

Ecoflux Corrugated Tube Heat Exchangers (CTHE’s) are shell and tube heat exchangers, which use corrugated tubes instead of plain (smooth) tubes.

Corrugated Tubes - Development Corrugated Tubes take the best features of both the plain tube and the plate heat exchanger. Plain tubes offer the best geometry to withstand pressure but the worst for heat transfer due to rapid build-up of boundary layer. Plates in a plate heat exchanger induce local turbulence to increase heat transfer coefficient but is limiting in terms of operating pressures and temperatures due to elastomer gaskets. Also, the relatively narrow gap limits its use to fluids without large fibres and particulates.
