Ultra low pressure rupture discs for sensitive pressure systems
Highly sensitive rupture discs engineered to activate at extremely low pressure levels for delicate process protection.
The burst disks that stay reliable even at the slightest pressures
The management of ultra-low pressures, which comes into play when protecting cisterns, silos and stocking tanks from implosion or breakage, requires the use of very special Bursting disks, which can be at the same time sensitive enough to match the levels typical of such applications and strong enough to not collapse spontaneously. One of the most frequent applications of such a product is in fermenters for biogas production.
DonadonSDD offers a range of rupture discs for low and ultra-low pressures, with a possibility for double protection (against both pressure and vacuum) and for mounting ATEX-certified rupture indicators which can immediately signal the disc’s rupture. All of these disc feature zero fragmentation.
