With innovative features and next-generation technology, DNF+™ Fully-closed Channel Element offers 10% higher efficiency for the same depth.
DNF+™ Fully-closed Channel Element all-new design allows for higher sootblower pressures, lowering fouling potential while increasing element life.
Known for developing the Ljungström® DNF® heating element, an industry-breakthrough twenty years ago, we’ve now established an all-new technology innovation that will once again revolutionize the industry.
Designed to ensure your operations run as smoothly, cost-effectively and efficiently as possible, DNF+™ Fully-closed Channel Element is our new and improved channel surface offering the highest cleaning effectiveness and significantly improved thermal performance.
Offering superior performance and a more flexible configuration, DNF+™ Fully-closed Channel Element is a fourth-generation closed channel heat transfer surface that will allow your business to meet environmental, efficiency and reliability challenges. DNF+™ Fully-closed Channel Element is also built to withstand higher sootblowing pressures, ensuring it lasts longer and reduces your O&M costs, making DNF+™ Fully-closed Channel Element a cost-effective option.
Globally-renowned provider of innovative and scalable heat exchanger solutions, LJUNGSTRÖM’s latest offering, DNF+™ 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 DNF+™ 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 DNF+™ Fully-closed Channel Element acts like a closed pipe.
Additionally, the DNF+™ 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. DNF+™ 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.
