Flexible Tubular Heater Installation – Nextflex

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.

  12. Nextflex Shapes square shape contact surface 75% round shape contact surface 50% square + round shape contact surface 72% NEW! - greater circumference than round shape - improved heat transfer

  13. Nextflex D-Shape • The new heater for 8.0mm grooves • Optimal heat transfer (above 72% and beyond)

  14. Nextflex Round vs. D-shape Note: Forming and stakingtoolsrequired to properlyinstall D Shape heater Traditional Round Shape Contact surface 50% Advantage: Ease of installation Innovative D-shape contact surface 72% Advantage: Improved heat transfer/energy efficiency Staking reduces need for holding mechanism

  15. Nextflex compelling advantage Excellent Heat Transfer Nexflex D-shape heaters proven to be faster and more efficient than our previous generation flexible heater in side by side test. Ask your Nexthermal representative to show you the video. User formable — Shipped in simple to install straight lengths Availability — Nextflex heaters ship same day from stock for orders placed before 2:00 p.m. Eastern Standard Time 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… 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.

  17. Nextflex heaters are simple and efficient 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 striking. 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.
