Helixchangers

Tired of cleaning shell & tube bundles due to high-fouling on the shell-side?

Helixchanger® shell & tube heat exchangers are best suited to high-viscosity and/or high-fouling shell-side processes. The helical baffle design allows us to maximize the shell-side velocity within an allowable pressure drop.  

Altex Industries was the first Helixchanger® Licensee in Canada and has fabricated over 100 Helixchanger bundles and exchangers since 2003. 

When compared to a conventional shell & tube exchanger, Helixchanger® designs result in:
  • Higher average shell-side velocity
  • Greatly reduced dead-zones (low-velocity areas).
  • Increased heat transfer
  • Reduced fouling (and reduced fouling-related corrosion)
  • Optimized and potentially smaller exchanger sizes
  • Reduced capital and operating costs.

Helixchanger® designs can reduce the total number of exchangers and/or reduce sizes – often at cost savings over conventional baffle types.

We can also retrofit your existing shell & tube heat exchangers with upgraded Helixchanger® bundles to help with performance and fouling issues.

Helixchangers® are a licenced technology of Lummus Technology.

“The HELIXCHANGER® heat exchanger uses Lummus Technology’s industry-proven, enhanced heat transfer technology to provide solutions for common issues such as shell-side fouling, high-pressure drop and vibration. In the HELIXCHANGER® heat exchanger, quadrant shaped baffle plates are placed at an angle to the tube axis in a sequential arrangement to create a helical flow pattern.  

Whether the need is to extend the operating period between cleaning campaigns of crude preheat exchangers, reduce capital costs in a petrochemical plant or improve energy-efficiency of feed/effluent towers, Lummus Technology’s advanced heat exchanger technology offers a lower life-cycle-cost solution.

Our experience and know-how comes from more than 4,000 HELIXCHANGER heat exchanger installations in refining, power and petrochemical facilities worldwide.”
