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

• Baffle-free design directs shell side fluid to true longitudinal flow.
• Each Twisted Tube is extensively supported at multiple contact points along its entire length.
• Tube fretting and failure due to vibration is eliminated.

• Twisted Tube technology's longitudinal swirl flow reduces the high pressure drop associated with segmental baffles.
• Twisted Tube exchangers are usually shorter in length and have fewer number of passes, for a lower pressure drop on the tubeside.
