The Snyder Industries 2000 Gallon Sodium Hypochlorite (UV) Captor Double Wall Tank (SKU 5570000N52) is a tank-within-a-tank configured for sodium hypochlorite (bleach) storage, where a spill can't be allowed to reach the ground. The primary vessel and its integral outer containment shell are molded from HDLPE resin #880059 in an opaque white finish, and the unit carries a 1.9 specific gravity rating - the number that tells you it's built to hold a dense liquid at full volume, not just water. If you're comparing double wall tank options for hypochlorite service, this is the Snyder Captor design that combines secondary containment and the storage vessel in one 2000 gallon footprint.
Will it work for your install?
The tank holds 2,000 gallons and stands 103 inches tall on a 102 by 102 inch footprint, so plan your pad and overhead clearance accordingly. Weight is where a double wall tank surprises people: filled with water it runs about 16,680 pounds, and at its maximum rated contents - the dense, high-SG liquid the 1.9 rating is meant for - it reaches roughly 31,692 pounds. Sodium hypochlorite is heavier than water, so your usable volume and freeboard don't track the water figure. That loaded weight drives your foundation, so size the slab for the real filled load, not the empty shell. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm capacity, and the Captor freeboard sizing guide (ASTM D1998) works the density-and-freeboard math for exactly this case, while the concrete pad sizing guide covers the ACI 360R-10 framework for a tank this heavy.
Fittings and access
Per the technical drawing on this page, the tank is configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for inspection and interior work. On a hypochlorite tank the vented fitting isn't optional hardware - bleach off-gasses, and that fitting is the pressure-relief path on a sealed double wall unit. Confirm the drawing's fitting locations against your piping and venting plan before you order. For containment-code context on this Captor design, the SPCC 40 CFR 112 walkthrough covers the secondary-containment requirements most buyers check.
The mistake to avoid
Don't spec by capacity alone. A 2,000 gallon double wall tank rated at 1.9 SG behaves very differently under load than a single-wall water tank of the same volume - the containment shell, the vented fitting package, and the near-16-ton filled weight all have to line up with your site. Verify the 1.9 SG rating covers your intended contents and that your foundation is built for the loaded weight before you commit.
