Nexthermal Tubular Heaters… the next generation flexible tubular heater.

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.

Nextflex heaters are simple and efficient

Efficient to Install Best PracticesNextflex tools reduce installation time and eliminate

the need for additional retention methods.

Making sure heater is directly above the groove, strike with Teflon® side ofNextflex 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 withexcellent heat transfer.

Form the first bend atcenter location prior tostriking.

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.

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.

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

Pneumatic hammer attachment.
