International brand dossier
Protec Arisawa is an Arisawa Group FRP pressure-vessel specialist for membrane filtration systems.It has three production sites on three continents and more than 50 years of filament-winding experience, making the brand relevant for RO, NF, UF, and desalination systems where vessel safety, pressure range, custom sizes, corrosion resistance, and replacement-part support are key selection issues.
Protec Bekaert Pressure Vessels's position in RO/NF membranes and related equipment is defined by product families such as Spares / manuals, Other documents, 600 psi Pressure Vessels and 1000 psi Pressure Vessels.
The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include Bekaert Progressive Composites-brochure, Protec User Manual Pressure vessels and Protec Arisawa FRP-Collectors.

Product range and selection
This section answers two questions: which main product families Protec Bekaert offers, and which parameters to compare before choosing a specific model.
The main families shown on this page are Spares / manuals, Other documents, 600 psi Pressure Vessels, and 1000 psi Pressure Vessels. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
After choosing a product family, compare pressure rating, element count, port layout, and code requirement. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
Showing 6 main families; all 12 appear in the model index below.
