Originally developed by Flexitallic in direct response to customers’ long-term heat exchanger sealing problems. Change™ is a highly-resilient metal-wound gasket, designed to deliver the most dynamic static sealing technology ever. Manufactured using proprietary equipment, Change™ has a proven track-record showing it outperforms conventional gasket technology in challenging environments, especially in applications with mechanical and thermal cycling conditions. It has also achieved independent industry accreditation from TA Luft for its ability to deliver the tightness of a Kammprofile with the recovery of a Spiral Wound Gasket. This is achieved through the application of a unique metal spiral profile, which is more advanced than those found in standard gaskets. This profile, combined with a laser welding process, facilitates the construction of a robust and dynamic seal.
