Flexible Tubular Heater Installation – Nextflex - PowerPoint PPT Presentation

  • Uploaded on

Nextflex tubular heaters are flexible heaters that are user formable, simple to install. These flexible heaters have an external sheath made of nickel braid and can be bent into virtually any shape. Nextflex tubular heaters are true to size heaters that do not expand when installed, eliminating risk of heated section outside of the manifold. Nexthermal can also assist you in selection, installation advice and improving application performance.

Eliminate guesswork — Nextflex true to size heaters do not expand when installed, eliminating risk of heated section outside of the manifold

Supporting tools — Reduce installation time and improve performance with Nexthermal installation tools

Technical support — Nexthermal can assist you in selection, installation advice and improving application performance

Nexthermal Tubular Heaters…

Heat Test: Previous generation flexible tubular heater (left) vs. the Nextflex (right). With Nextflex you are the clear winner.

Side by side test data demonstrates that Nextflex heaters transfer more heat to your tool. The chart shows that the Nextflex heater is very close to the tool temperature when our previous flexible heater shows a differential of more then 100Cº.

Best Practices

Efficient to Install

Nextflex tools reduce installation time and eliminate the need for additional retention methods.

Making sure heater is

directly above the groove,

strike with Teflon® side of

Nextflex forming tool.

One hard strike is better

than two soft ones.

Strike the Nextflex staking

tool hard every 20mm

(~.75"). This creates a

Firmly seated heater with

excellent heat transfer.

The first 10mm (~.40") after the connection area should always be straight.

For bending the Nextflex we recommend our Nextflex toolset. This will allow the Nextflex to be seated optimally into the groove, resulting in maximum heat transfer.

Form the first bend at

center location prior to


When bending, make sure the Nextflex tool handle is parallel with the uninstalled Nextflex. This puts the minimum bending radius protection in the correct position.

For optimal heat transfer, it is best to stake the Nextflex after assembly approximately every 20mm (~.75") into the groove.

Pneumatic hammer attachment.
