Features

Baffle-free Design

The tube geometry allows for the tubes to be self-supporting, eliminating the need for baffles. 

Cleanable Triangular Pitch

The assembly geometry creates multiple cleaning lanes, which allows for the center of the bundle to be accessed. 

Compact Tube Bundle

Due to the self-supporting tube geometry triangular pitch, more tubes can fit into a single shell size as compared to conventional round tubes.

E-F Conversion

The shroud design of the TWISTED TUBE® heat exchanger allows for a more efficient F bundle used inside an existing E shell. The shroud creates a two-pass configuration and eliminates a full-length leaf seal that would be prone to damage. 


TWISTED TUBE® Bundle Technology

Designed to Be Different

We looked at typical problems with Shell & Tube exchangers and made it our mission to solve them with a revolutionary bundle construction. Through ongoing research, TWISTED TUBE® heat exchangers can be more efficient, reliable, and trouble-free when compared to conventional shell and tube heat exchangers.

Our innovative design eliminates baffles and damaging tube vibration. The uniquely shaped tubes are arranged on a triangular pattern that provide adjacent support as fluid swirls freely alongside. Gaps between the tubes make it easier to clean on the shell side. Rounded ends allow for the use of conventional tube-to-tubesheet joints.

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.

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.

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.
