Reduce Emissions.  Boost Profitability. No Piping Changes Required.

Numerous operating companies are retrofitting their shell and tube heat exchangers with revolutionary TWISTED TUBE® Heat Exchanger technology for improved performance.

Join the Evolution! 

Elimination of Damage-Induced Vibration

Due to the generally longitudinal flow pattern of the shell-side fluid and the multi-point support structure of the bundle, the potential for flow-induced damaging vibration is mitigated.

Increased Heat Transfer

Allowing for more surface area in a given shell size, the throughput can potentially be increased based on the application. Increasing the tube-side heat transfer coefficient can provide increased heat transfer, based on the application.

Reduced Pressure Drops

The longitudinal flow allows for a lower relative pressure drop when compared to segmental baffle designs.

Potential Fouling Mitigation

The elimination of shell-side baffles eliminates dead spots where sediment can accumulate and cover heat transfer surface area.

The swirl flow on the tube side increases the shear velocity, ultimately decreasing the fluid boundary layer.

Reduced NOx and Emissions

TWISTED TUBE® Heat Exchanger tube bundles can enhance performance and increase the outlet temperatures of your crude oil or feed upstream of a fired heater, reducing energy consumption and NOx emissions from those fired heaters.
