TF4 Fully-Closed Channel Element Offers a Range Of New and Improved Features That Elevate It From the Competition

 

Globally-renowned provider of innovative and scalable heat exchanger solutions, LJUNGSTRÖM’s latest offering, TF4 Fully-closed Channel Element, is a fully-closed channel surface offering not only the most effective cleaning but also a significantly improved thermal performance. Cleverly designed with attention to paid to every detail, our all-new TF4 Fully-closed Channel Element will change the way your business operates.

With all the features of our globally proven DNF element, our latest profile also offers a range of new and improved features including a fully-closed channel design with continuous flat to notch contact, and physically closed channels, to ensure TF4 Fully-closed Channel Element acts like a closed pipe.

Additionally, the TF4 Fully-closed Channel Element boasts closed channels that contain cleaning energy through the full depth of the basket, reversing undulations on every sheet to promote turbulent flow and efficiency, and notches to stiffen every sheet and improve resistance to mechanical damage. TF4 Fully-closed Channel Element’s smart features prevent cleaning energy diverting around deposits and allow for the ready removal of deposits at lower cleaning pressures.

Enhanced geometry

To optimize notch and undulation heights and angles, creating the perfect balance of heat transfer and pressure drop.

All-new stabilizing notch

Strategically placed on the profile geometry in order to improve mechanical stability and sootblowing capabilities

Next-gen Technology

Offering improved weight to efficiency ratio
