Sanitary Pressure Relief
Pure-Gard is an innovative, sanitary pressure relief solution specifically designed for applications where cleanability is of paramount importance. The new disc design provides a cleanable, robust solution to address the challenges of complex manufacturing environments including pharmaceutical, biopharmaceutical and food.
Crevice and dimple free design
Pure-Gard meets industry expectations for cleanability with its crevice and dimple free design. Our rigorous testing program includes dye penetrate testing and helium leak testing.
The one-piece design protects the rupture disc, avoiding the risk of damage at the point of installation. Pure-Gard’s structural stability also means its performance is unaffected by vent-side pipework loads.
Extended product life
Pure-Gard provides a solution independent of the gasket, allowing regular change of gaskets without needing to change the disc. This innovative design feature extends the life of Pure-Gard beyond conventional sanitary pressure relief solutions.
Pure-Gard SoLo is a low pressure variant suitable for use in processes where pressures are as low as 5 psig.
Reusable modular detection
Pure-Gard and Pure-Gard SoLo are designed for use with our Vent-Tel burst detection system, which is an independent, reusable and non-invasive solution. The Vent-Tel is mounted directly to the Tri-Clamp,making disc inspection and replacement quick and simple.
The Elfab Pure-Gard is manufactured at Elfab’s manufacturing facility in North Shields, Tyne & Wear, UK.
Bio processes normally require constant temperature. Biological fermentation is a major source of heat, therefore in most cases, bioreactors need refrigeration. Should refrigeration fail, the heat generated could create an unsafe operating condition and require over pressure protection.
Rupture discs are commonly used as the primary relief device on Pharmaceutical tanks. Rupture discs will need to withstand full vacuum, and are generally rated at approximately 45 psig. Oseco's Pro-S is an excellent choice for this application, and fits directly into existing sanitary ferrule connections.
