Helixchanger®

  • Improve the Performance
  • Features and Applications

Within its wide heat transfer solution range, Koch Heat Transfer Company, under license from CB&I Lummus Heat Transfer, is able to offer HELIXCHANGER® heat exchangers.

The HELIXCHANGER® is a shell & tube heat exchanger in which baffles are arranged in a helical pattern to create a continuous helical flow on the shell side.

Among several units, Koch Heat Transfer Company manufactured and delivered the largest HELIFIN® heat exchanger (HELIXCHANGER® heat exchanger with low-finned tubes - see photograph below) and Helitowers ("Texas Tower" heat exchanger with Helixchanger® bundle).

Features

Compared with conventional shell & tube heat exchangers, HELIXCHANGER® heat exchanger has the following advantages:

  • Reduced shellside fouling
  • Higher shellside heat transfer coefficient
  • Lower vibration risk
  • Lower shellside pressure drop
  • Improved two-phase flow distribution
  • Cost saving on total life-cycle basis
  • Elimination of dead zones that exist in conventional segmental baffles
  • Increased B-stream flow fraction at the expense of A- and E- flow fractions

Application

HELIXCHANGER® heat exchanger is best suited for services in which shellside heat transfer plays a determining role and/or shellside pressure drop is controlling and where reduced shellside fouling or flow-induced vibration are a concern. Shellside media may range from hydrogen-rich gas to viscous fluid with high fouling tendencies, in single or two-phase flow.

Typical applications are in the gas processing, refining, petrochemical and chemical industries.
