CORRUGATED TUBES

A corrugated tube heat exchanger offers significant improvements both in heat transfer and energy efficiency.
When the fluid flows through a corrugated tube, vortexes are created inside and outside the tube. These vortexes increase the amount of fluid in contact with the tube surface, thus improving heat transfer compared to smooth tubes.

Another advantage of the corrugated tube is that its special shape produces turbulences that have a strong self-cleaning effect and thus prevent fouling inside the heat exchanger.
In addition, corrugated tubes do not require expansion joints for thermal stress because they can withstand high temperature changes.
Corrugated tubes are ideal for heat exchangers used in systems of the food, naval, chemical, pharmaceutical and refrigeration sectors.
