OC Commercial / Industrial & Residential FRP Tanks:

OC produces "Pre-Engineered" fiberglass water tanks and environmental products for the water industry. OC FRP Tanks are constructed in accordance with American Welding Society Specifications, AISC, NFPA, Uniform Building Code, and are City Approved. OC Tanks are designed and fabricated to specific project specifications and size requirements.

OC commercial / industrial FRP tanks have high grade vinylester tank liner, and OC residential fiberglass water tanks have high seamless, one-piece ABS tank liner. Blow molded ABS shell promotes superior adhesion to filament wound outer laminate. For all OC FRP tanks, fiber-free inner surface suitable for all standard water treatment applications, including de-ionization and offers wide chemical resistance; not adversely affected by regenerating chemicals (acid-caustic) or DI water. Strong, filament wound outer laminate of OC FRP tanks have continuous stands of fiberglass reinforced with high strength epoxy resin, and they are rustproof and corrosion-resistant. Precision injection-molded threaded tank openings, Filament wound fiberglass flanged top and bottom openings full coupling, threaded dome and side hole options are available. These tank openings also accommodate all industry standard valves and fittings. Maximum operating pressure of OC Commercial / Industrial Tanks is 150 PSI (10.2 BAR), and maximum operating temperature is 120°F (49°C).

Structural Residential and Light Commercial Fiberglass Water Tanks:
Structural FRP tanks are the ideal choice for residential and light commercial water treatment applications that require flexibility. Structural FRP vessels improve your water treatment system and they are easy to handle and install. Structural FRP vessels are available in standard polyester or chemical-resistant vinylester construction depending on your needs. Structural uses FRP with polyethylene inner shell as a material of construction. Their standard color is natural, and other colors are available upon request. Structural FRP tanks have top opening with 2.5"-4.5" threaded, or 6" flange. Their maximum operating pressure is 150 psi (1 MPa), and maximum operating temperature is 120°F (49°C).
