Pressure relief device for cryostats

Jon Lawson

As an organisational unit of the Karlsruhe Institute for Technology, the key focus of the ITEP is on superconductivity and cryogenic technology. The scientists are currently working on nuclear fusion, energy technology components and the development of high-energy magnetic fields. With its comprehensive, practice-oriented service programme, the institute is an established player in the international R&D sector.

To provide clients and customers with the required services reliably and quickly, the institute focuses on high-quality equipment. This includes the rupture discs that have been in use for the institute’s cryostats since 1996. The discs were supplied by German rupture disc manufacturer, Rembe.

“Cryogenic processes and applications are one of our main specialties,” says Dr Stefan Rüsenberg at Rembe. Friedhelm Kesting, production manager for more than 25 years, adds: “We have already secured a wide variety of processes, from deep-sea applications all the way up to space satellites. I am personally very proud to hear that our rupture discs have been providing reliable protection for such a long time.”

According to the manufacturer, the most important factor with cryostats is that the pressure relief used is leak-proof. Therefore, they recommend welded compact rupture discs that, in addition to the low leak rate, also offer a response at low burst pressures and very high vacuum resistance.

Rembe employees see the great advantage of the rupture disc compared to a safety valve in the fact that, unlike a safety valve, a rupture disc cannot freeze up.
