Sanitary rupture discs for pharmaceutical, food and biotech processes
Hygienic rupture discs designed for sterile environments and compliant with sanitary requirements in regulated industries.
3-A rupture discs developed specifically for the sanitary sector
Pharmaceutical, food, and biotechnological industries require rupture discs that ensure compliance with the most stringent hygiene regulations, which are essential for these types of production processes.
That’s why DonadonSDD rupture discs have been designed to meet the high quality standards required by 3-A SSI, whose aim is to ensure public health through hygiene equipment.
DonadonSDD discs are entirely made of AISI 316L stainless steel (or other alloys upon request of the client) and feature a smooth surface. They can undergo procedures that include C.I.P. and S.I.P. treatments to maintain aseptic conditions. Moreover, our rupture discs can be inserted into Clamp fittings or Tri-Clamps, thanks to PTFE gaskets complying with FDA, USP class VI, 3-A, and Eu 10/2011 regulations, and are non-fragmenting, i.e. they rupture without producing pieces.
