The TWISTED TUBE® bundle advantage

Improving efficiency

Improvements over conventional shell & tube heat exchangers:

Increased heat transfer coefficient

• Swirl flow creates turbulence resulting in higher tubeside coefficient.
• Uniform fluid distribution combined with interrupted swirl flow results in optimized shellside coefficient.

Lower pressure drop

• The longitudinal swirl flow of TWISTED TUBE® bundle technology reduces the high pressure drop associated with segmental baffles.
• TWISTED TUBE® heat exchangers are usually shorter in length and have fewer passes, for a lower pressure drop on the tubeside.

No vibration

• Baffle-free design directs shellside fluid to true longitudinal flow.
• Each tube using TWISTED TUBE® bundle technology is extensively supported at multiple contact points along its entire length.
• Tube fretting and failure due to vibration is eliminated.

Reduced fouling

• Baffle-free design eliminates dead spots where fouling can occur.
• Velocity is constant and uniform.
• Constant flow distribution controls tube wall temperature.
