danger to people, and the environment if there is insufficient protection with regard to pressure relief. Last but not least, there is a high monetary loss for operators. Special safety valves and rupture discs are therefore necessary to ensure an adequate long-term protection.

over the long term. Premature response is thereby prevented - this protects against product loss and unnecessary downtime.

In addition to the advantages already mentioned, the welded compact rupture discs offer two additional highlights which further increase the leak-tightness: since a so-called reverse- acting rupture disc (bulge of the rupture disc faces the process) is installed, relatively thick material can be used even at very low response pressures, which prevents a diffusion of the process medium. In addition, these rupture discs are absolutely vacuum resistant even at very low burst pressures without the need for an additional vacuum support. This is

important, because vacuum supports make a sterilisation impossible. However, this is exactly what is required for sterile, demanding processes or ultra-pure gas applications.

Suitable process connections are individually agreed with the operator and implemented accordingly. Due to the design of compact rupture discs, almost all types of flange and threaded connections can be installed (or example, CF connections or Swagelok threaded connectors). In addition, these rupture discs or their housings can be electropolished. The units can also be supplied with surface finishes suitable for high purity and sterile applications.

In short: Cryostats and other containers for cryogenic media can become a great
