Composite Pressure Tanks
swtwater.com Fiberglass Wrapped & PP Liner
These are the first tanks on the market to feature a 100% polypropylene (PP) copolymer inner lining for all wetted materials. This makes it the perfect tank for drinking water applications, D.I. exchange, laboratory, and applications where chemical resistance is required. Call to ask us about optional dome holes, bottom holes, or custom lengths.

FEATURES:
Wound with continuous premium fiberglass to provide superior strength under pressure
Custom formulated co-polymer polypropylene inner shell provides superior elasticity and impact resistance
Extruded side wall produces consistent wall thickness and eliminates potential thin spots or stress points
Base is injection molded from impact/temperature resistant polypropylene
Certified to NSF/ANSI Standard 44
Available in natural, almond, blue, black, gray
Made in the USA
10 year warranty for tanks up to 13 inch in diameter;
5 year warranty for larger tanks
 
OPERATING PARAMETERS:
150 psi maximum operating pressure
120ºF (50ºC) maximum operating temperature
 
DESIGN PARAMETERS:
250,000+ cycles, ambient and hot 150ºF (66ºC), 0 to 150 psi without leakage
4:1 Safety Factor (600 psi minimum burst)
Stress Rupture: 1000 hours minimum at 150ºF (66ºC) and 150 psi static pressure
 
 
Tank Thread Top Threads — High temperature/high pressure injection molding allows the glass-filled threaded inlet to be mechanically and chemically welded to the dome, eliminating potential leak paths.
   
Poly Bases Poly Bases — DI Exchange vessels are available with a high impact and abuse resistant plastic Poly Base that offers superior rolling characteristics, reduced transportation weight compared to traditional rubber bases, reducing overall cost and shipping weight of the vessel, and design characteristics that will keep the base attached to the vessel.

TANK WARRANTY:
Residential polypropylene-lined pressure vessels (up to 13 inch diameter) are warranted to be free of manufacturing and material defects for a period of 10 years if operated within specifications in residential water treatment applications. Commercial and industrial sizes (greater than 13 inch diameter) are warranted for a period of 5 years. Warranty coverage excludes freezing, vacuum, corrosive materials exposure.
These vessels are only approved for H2O pressure use. All other uses or solutions to be used must be approved by manufacturer.
These vessels are not to be used for pneumatic or hydro-pneumatic applications.
 
 
VACUUM PROTECTION & FLEX CONNECTORS
Fiberglass/composite pressure vessels are rated for an internal negative pressure of 5-inches Hg (17 Pa) vacuum below atmospheric. If negative pressure could ever exceed 5-inches Hg (17 Pa), an adequate vacuum breaker must be installed between the pressure vessel inlet and any valves (see illustration right). For enclosed tank applications, the vacuum breaker should be installed at the highest location in the system plumbing.

System connections to the pressure vessel must accomodate vertical expansion between side, top, and bottom openings. Either flexibility in piping or flex connectors, as shown here, are recommended.
