NSF/ANSI 61 Certified Tank Systems

NSF/ANSI 61 Certified Tank Systems

NSF/ANSI 61 is a set of national standards that relates to water treatment. It establishes stringent requirements for the control of equipment that comes into contact with either potable water or products that support the production of potable water. The tests vary from a basic cold water test at different pH levels to the more challenging chemical certification.

Many manufacturers have certified tanks, but their fittings and gaskets may not be NSF/ANSI certified. Poly Processing is the only chemical storage tank manufacturer to take a full system approach to NSF approval. We supply an entire tank system, including fittings, gaskets and specific tank colors, that are certified for NSF/ANSI 61.

Cross-Linked Polyethylene (XLPE) Tank

Cross-Linked Polyethylene (XLPE) Tank

Not all high-density polyethylene tanks are created equal. Although they sound nearly identical, linear polyethylene and cross-linked polyethylene (XLPE) chemical storage tanks have significant differences. Those differences could impact your organization’s bottom line, your people’s safety, and the operations of your facility.

The four most important factors of high-density linear tanks and cross-linked tanks include:

  • Environmental stress crack resistance/notch sensitivity
  • Long-term hydrostatic strength
  • Toughness and Durability
  • Useful Life

Compared to linear polyethylene, XLPE provides:

  • 10-20 times the environmental stress crack resistance
  • 10 times the molecular weight
  • 3-5 times the impact and tensile strength

Because XLPE has a significantly longer life and less financial impact in case of tank failure, the total useful life of cross-linked polyethylene is significantly better for your bottom line.

Integrally Molded Flanged Outlet® (IMFO®) Tank

Integrally Molded Flanged Outlet® (IMFO®) Tank

Poly Processing’s Integrally Molded Flanged Outlet (IMFO) Tank is a homogenous full discharge flange system that is molded as part of the tank while it’s being manufactured. As a result, the outlet is a fully integrated, stress-free part of the tank. The flange is created from the same material as the tank, and it’s not a fitting or accessory that’s added during post-production.

An IMFO Tank delivers a number of benefits to a chemical tank storage system that a metallic insert simply can’t offer. These include:

  • Full tank discharge, because the flange is at the bottom of the sidewall, below the tank knuckle radius. There’s no longer a need to enter the tank for cleaning.
  • Enhanced long-term performance and fuller useful life of the tank, since the flange doesn’t compromise the tank’s hoop integrity or structural design.
  • No connection points to provide opportunities for leaks as the tank ages.
  • Complete flange face protection is available in aggressive oxidation environments. The antioxidant OR-1000™ system can protect the discharge components and give you greater useful life.
  • Highest amount of static head pressure. The IMFO’s design brings you the highest net positive suction head (NPSH) of any vertical non-coned tank on the market.
  • Any required maintenance is simple and hassle-free. Unlike metallic inserts, the flange extends away from the tank wall and the entire flange system is external with easy hardware access from outside the tank.
  • There are no chemical compatibility issues like the ones you may encounter with metallic inserts. If the chemical is safe in a crosslinked polyethylene tank, it’s safe discharging out of the IMFO system.

Sloped Bottom Vertical IMFO® Tank

Sloped Bottom Vertical IMFO® Tank

The Sloped Bottom IMFO tank is a specially designed IMFO tank with a sloped bottom. This version excels when it comes to discharging heavier materials such as FOG (fat, oils, and grease) or sludge like materials. The sloped bottom creates an additional gravity feed that makes it easy for substances to discharge completely, leaving no residue or sludge to build up.

The Sloped Bottom IMFO Tank is more cost effective than cone-bottom tanks, and it comes with fewer drawbacks such as the need for special mounting on metal support frames.

Cleaning is simple, because there is no need for a confined-space entry. Instead, the sloped bottom tank can be cleaned from the top manway, or with a spray ball installed in the dome. It’s a solution that’s much safer for your personnel, and more cost-effective.

OR-1000™ System

OR-1000™ System

If you have aggressive oxidizing chemicals that you’re storing, Poly Processing has you covered. Our OR-1000 System adds an antioxidant barrier between aggressively oxidizing chemicals and your high-density crosslinked polyethylene tank.

The OR-1000 System is specifically formulated to resist oxidation and give you greater tank life. The outer surface is made of XLPE and offers superior strength, longevity, and chemical resistance. The inner surface provides an additional antioxidant resin barrier. The two surfaces are molecularly bound together during tank production, creating a truly seamless bond between the XLPE and the inner surface of the polyethylene tank.

The OR-1000 System addresses the chemical resistance of oxidizing chemicals for 15+ years. The system isn’t your typical resin. In fact, it has four times the antioxidizing power, compared to other commercially available resins. This high level of antioxidant additive ensures greater longevity for your tank.

SAFE-Tank® Double Wall Tank System

SAFE-Tank® Double Wall Tank System

Poly Processing’s innovative SAFE-Tank® double wall storage and containment system, the “tank within a tank,” provides you with a cost-effective solution that offers peace of mind and environmental care.

The high-density crosslinked polyethylene SAFE-Tank alleviates the need to build large, high-maintenance concrete containment areas. In the event of a spill, the SAFE-Tank’s all-in-one design features a protected containment area that safely isolates reactive chemicals, protects your employees from harm, and protects you from environmental remediation, all within the footprint of a standard vertical tank.

And because the containment area is enclosed, your spilled chemical is protected from water and contaminating debris that can enter traditional secondary containment areas.

The SAFE-Tank Double Wall Tank System:

  • Provides at least 110% secondary containment.
  • Equalizes spilled liquid and allows the chemical to be used until it is convenient to repair the tank if necessary.
  • Is ideal for chemicals like sulfuric acid that can have dangerous exothermic reactions to water.
  • Eliminates the expense, cost, and maintenance of secondary concrete containment.
  • Minimizes the system’s footprint by providing secondary containment in a more compact way.

Poly Processing’s Bellows Transition Fitting

Poly Processing’s Bellows Transition Fitting

When you install a double wall chemical storage system like the SAFE-Tank with a sidewall fitting, it may be important to also install a Bellows transition fitting. The Bellows transition fitting has a flexible expansion joint that is in line with the outlet pipe that runs through both the inner and outer walls of the SAFE-Tank.

The transition fitting fully contains both the fitting and piping from the inner tank, through the outer tank, to the outlet. If the fitting or any of the seals becomes overstressed and fails, the leak is contained inside the bellows. The leaked chemical flows back to the containment space between the inner and outer SAFE-Tank walls.
