Gasket improves heat exchanger performance F
lexitallic’s Head of Engineering, Russ Currie, has overcome customers’ complex technical issues
with poor performing sealing heat exchangers with an innovative new gasket, Change. The Change gasket delivers a more dynamic seal, with superior compression and recovery than
any other gasket on the market*. Change can be supplied with Thermiculite,
PTFE, graphite filler and a wide variety of other metals, making it suitable for an extensive range of applications. Across a 24-day, 24-cycle pressure vs thermal cycle test at 302˚C replicating industry application conditions, the Change gasket lost just 0.1bar and, says Flexitallic, never came close to the failure point. The high level
of stored energy gives the Change gasket extremely high recovery. In a compression test against other heat exchanger gaskets, the Change gasket recovered
ring in all sizes upon request. Russ Currie said: “We developed a unique
sealing construction and new welding process to engineer ‘Change’, which was created in direct response to customers’ long-term problems. ‘Change’ has out-performed all alternative
gaskets we have tested to date, including our own, and now we are seeking out customers with troublesome applications to challenge ‘Change’ to dramatically improve performance. “Efficiencies in production methods have also enabled this new technology to be a cost-effective solution for customers.” ●
* Based on Radial Shear Testing (RAST), thermal cycling and leakage tests: Modified Shell Test, ROTT and Compression testing.
