Protec Quality

Highest Quality Product Available
Our products are expected to last the entire life of the RO system. To ensure the life of the pressure vessel, we have selected the best materials and used the newest technology for filament winding. When you select PROTEC™ products, you get the best RO Vessels in the worldwide market.
Operational Excellence and First Time Quality
First time Quality and Operational Excellence are our focus. When facing complex situations, our R&D Team provides the best Technical Support as well as a huge degree of Customization. We are the reference for Customer Care & After Sales Assistance. We also display a supple and adaptive Lean time Production Line to meet the most urgent time demands.
Leak Free Reliability
PROTEC™ pressure vessels are all tested including the specific heads that will be shipped with each vessel. This attention to detail allows us to claim the best leak-free reliability record in the industry. Nobody wants to deal with leaks caused by poor workmanship, low quality materials or insufficient in-house testing. With Protec Arisawa, you receive high quality leak-free vessels, first time every time.
ASME Code
We are designing and producing 100% of our Vessels following the ASME Code, the most respected International Safety Standard Regulation upon Fiber Reinforced Plastic Pressure Elements written specifically for fiber reinforced plastic pressure vessels. Upon request, PROTEC™ pressure vessels can be supplied with an ASME Code stamp and a National Board Registration number.
Side Ports Range
Protec Arisawa displays a great range of different types of permeate port connections. The Side Port length can be adjusted to meet your skid design requirements at any case. Besides, we are able to provide in all our vessels with a very accurate side port position due to our CNC machining Division allowing optimal skid construction and minimizing stress on the side port during operation.

Best Materials

When it comes to FRP (Fiber Reinforced Plastic) Pressure Vessels, the materials of construction play a very important role. The materials determine the life of the vessel and well as the corrosion resistance and the purity of the water produced.

Metal Components
Metals are also used for some components. Our Side Ports are designed & produced out of top quality pipe to avoid any corrosion issue in the future end. The metal is selected for strength, corrosion resistance, purity and durability in service always meeting ASME/ASTM requirement, being 100% lot traceable to the serial number of each vessel.
Plastic Components
PROTEC™ pressure vessels use thermoplastic components when corrosion resistance is critical. We select them for strength, corrosion resistance, purity and durability in service. They are domestically manufactured & certified to meet ASME/ASTM requirements and listed by NSF for potable use, being 100% lot traceable to the serial number of each vessel.
FRP Shell
PROTEC™ pressure vessels are filament wound using fiberglass roving and a custom blended epoxy resin system that has been cured at an elevated temperature for dimension stability and long life. The resin has been specifically formulated for long cycle life as well as improved cure for better performance in tough service environments. All shell materials are domestically manufactured & certified to meet ASME requirements and 100% lot traceable to the serial number of each vessel.
Operational Ease
Our Vessels have a smooth internal surface to optimize the membrane loading and avoid the bacteriological growth inside. We have imposed the quad seals for the heads of our vessels being the head installation faster and easier to get a perfect seal. We work every day to provide with a better use experience. As an example, you can exchange some of our Vessels elements, such as joints, without need of removing couplings and Side Ports, something capital and relevant in a Plant daily routine.
Special Products
Protec is a Composite expert organization providing technical solutions for most of the Industrial Sectors requiring alternatives and creative developments with these materials. We are providers for a number of Industrial fields (Electrical, Chemical, Shipping, Transports, Telecom,..) a variety of products (Rolling insulating panels and plates, Molding by compression (SMC), Poltrusion, Manual Molding,…) Our Composite materials have many advantages for different applications (Electrical and Thermal insulation, Lightness, Chemical Resistance and Hardness, Design options,..) offering you a complete Engineering & Production Methods & Technical Assistance catalogue.

Zero Leaks

With our Leak Prevention Program Protec Arisawa has you covered with all the replacement parts, field service support and operator training to ensure your system is operating leak-free and safely.

Have you checked your seals lately?
The membrane housing is meant to be a closed system and all water should be contained within and all leaks stopped as soon as possible. The outside of the vessel, especially the head area, is not designed to be wet and no sitting water should be present. Protec can help you identify the cause of vessel leaks, get the proper replacement parts and provide our expert team to fix them.
What spare parts do you have in stock?
Protect your asset! No leaks or external water should be tolerated on your system. Subject to operational uptime, seals have an average life of 3-5 years and should be inspected and changed regularly. High and low pH exposure can decrease the life of a seal and the frequency for change will vary depending on how the system is operated and cleaned.
Did you know vessel leaking and external water can damage your vessel?
Enough seals for at least 10% of the vessels should be kept in stock at an operating facility and changed regularly. It is important for every operating plant to keep a safe level of shelf spares on site for emergency and routine maintenance. Permeate ports, thrust cones, membrane adapters and shims are common items that should be on hand.
Want to know how to prolong the life of your vessel and safely operate the membrane housing?
Protec Arisawa’s field service team provides operator training and general maintenance guidelines to ensure seals are secure and the vessel integrity has not been compromised. Our highly experienced field service engineers and technicians will efficiently and expertly disassemble, clean, inspect, and replace all the parts of the pressure vessel to ensure seals are securely placed and the vessel’s integrity has not been compromised. Fixing leaks and keeping vessel heads dry will ensure the safe operation of the system and prolong the life of the vessel. Should you need assistance in troubleshooting pressure vessel leaks, please contact Protec Arisawa or your Original Equipment Manufacturer (OEM). Protec Arisawa keeps a large inventory of spare parts at both our factories in Vizcaya, Spain and California, USA, for immediate delivery to OEMs and End-users. All vessel parts should be kept clean and free of debris and corrosion. All internal and external vessel parts should be regularly inspected for possible cracks or wear. Contact your authorized Protec Arisawa representative or account manager today for part numbers and pricing.
