Graver Technologies LLC introduces a new line of advanced stainless steel backwashable precoat septa for reactor water cleanup (RWCU), fuel pool and other specialty applications in nuclear power generation.

Aegis PowerGuard® stainless steel elements are designed to fit original Graver bottom tube sheet installations. Other fittings and adapters can also be provided. This ALARA solution for filter replacement in highly radioactive environments also avoids the removal of original tube sheet adapter hardware and the possibility of internal damage. Constructed of 314L stainless steel, Aegis PowerGuard elements incorporate Poroplate® an advanced sintered metal design that allows for precise control of porosity (from 2 to 200 microns) along with the durability, quality and reputation that Graver is known for.


PowerGuard Features Include:

• Low pressure drop
• Virtual elimination of contaminant leakage
• High strength and excellent resistance to corrosion & fatigue
• Collapse strengths over 400 PSID
• All low carbon 316L stainless steel construction
• Temperatures up to 1000°F
• Excellent cleaning & precoating characteristics
• Engineered and manufactured in the USA under ISO 2000


Aegis PowerGuard elements are available for top tube sheet designs as well as replacements for all OEM designs including Delaval & Croll Reynolds. PowerGuard can be supplied in any diameter, length & end fitting configuration. They are available as individual elements or as pre-assembled tube bundles.

Graver PowerGuard specialty metal products incorporating Poroplate sintered metal technology include stainless steel pleated resin trap elements, specialty underdrains, strainers, and resin traps. Custom designs are available to retrofit equipment for power upgrades or to extend operating life.
