Working in partnership with our subsidiary, Bendel Tank & Heat Exchanger, TransTech is an industry leader in the custom design and fabrication of shell and tube heat exchangers.

Together, TransTech & Bendel fabricate the highest quality heat exchangers available to accommodate a wide range of applications and budgets, including:

  • Fixed Tubesheet:  Two stationary tubesheets attached to the shell, a bundle of straight tubes is connected between the tubesheets and contain baffles to direct the flow around the tubes in order to generate the required heat transfer. A channel cover assembly is attached to each tubesheet.

  • Floating Tubesheet:  This design is similar to the Fixed Tubesheet design except one tubesheet is allowed to move axially within the shell while the other tubesheet is fixed. This configuration allows for the tube bundle to be removable.
  • U-Tube:  Consists of straight length tubes bent into a U-shape with both ends terminating at the tubesheet. The tube bundle is fitted with supports or flow baffles. The tubesheet/tube bundle is placed in the shell and bolted between the head flange and shell body flange. A head assembly is required to direct the fluid in and out through tube bundle. This configuration allows for the entire tube bundle to be removable.
