Abstract
A pressure relief module, such as a rupture disk module or a burst panel module, is disclosed. A pressure relief module may comprise a first membrane (10) configured to seal an opening of a contained system and configured to burst open when a pressure in the contained system reaches a predetermined burst pressure. A second membrane (20) may be joined to the first membrane to form a membrane interspace (30) with the first membrane. The membrane interspace (30) may be configured to prevent a backpressure in the contained system from changing the burst pressure required to burst open the first membrane (10). A pressure relief module may provide advantages for a low-pressure enclosure and/or to provide temperature stability and/or backpressure stability.
