PROTEC™ 8" Diameter Side Port Fiberglass (FRP) Pressure Vessel Membrane Housings
PROTEC™ pressure vessels are constructed of corrosion resistant filament wound fiberglass reinforced epoxy tubing and are designed for continuous use as housing for membrane filtration elements to purify typical brackish waters (150 -600 PSI) and seawater (1000 & 1200 PSI).
This style of fiberglass membrane housing is designed for direct connection to FilmTec/DOW style elements and is supplied with the element interface hardware for this style.
Side ported vessels with feed and concentrate connections located in the side wall of the vessel shell. 8" Side-Ported Vessels are available to house from one to eight 40" elements as well as one to five 60" elements. Available operating pressures are 150, 300, 450, 600, 1000 and 1200 PSI. To view details of the products, please see the product listings below.

PROTEC Pressure Vessel membrane housings have been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. At an additional cost, vessels can be inspected during fabrication by an ASME Authorized Inspector and Code stamped.
Materials
Shell: Filament Would, Epoxy FRP
End Plugs/Sealing Plates: PVC Thermoplastic
Retaining Rings: Stainless Steel
Hardware Components
Pressure vessels include shell, end enclosure hardware and seals. Mounting straps and components are sold separately.
