The Snyder Industries 1550 Gallon Sodium Hypochlorite (UV) Captor Double Wall Tank is a factory-integrated secondary containment system: a primary tank nested inside an outer wall, so a single unit gives you built-in spill protection without a separate berm. It stands 136 inches tall on a 76 x 76 inch footprint and is molded in opaque white HDLPE (resin #880059) with a 1.9 specific gravity rating - a heavy-duty double wall built to carry dense contents at full volume. Snyder configures this unit for sodium hypochlorite service, and the opaque white wall keeps UV out of the stored bleach.
Will it hold what you need to store
Rated capacity is 1,550 gallons. Filled with water, the contents weigh 12,927 pounds; at the tank's full 1.9 specific gravity rating the contents can reach 24,561 pounds, so plan your pad and anchoring for the maximum rated load, not just water weight. That 1.9 SG rating is why this Captor is rated for dense contents like sodium hypochlorite at full volume. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit, and confirm freeboard for thermal expansion using our Captor double-wall freeboard sizing guide so the volume you order is the volume you can actually use.
Fittings, access, and chemical seals
Per the technical drawing on this page, this double wall tank comes configured with a flange, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for interior entry, gauging, and maintenance. Those are your three sealed interfaces - the flange gasket, the 18-inch threaded/vented seal, and the manway gasket - and each one contacts your stored chemistry. Sodium hypochlorite is aggressive to many elastomers, so confirm every gasket and seal compound against your concentration before you plumb the site, and review the drawing for exact fitting locations and elevations.
Containment and pad support
The integrated outer wall makes this Captor a natural fit where secondary containment is required, and the 76 x 76 footprint IS the containment footprint - there is no separate berm pad to size beyond the tank pad itself. If your installation falls under SPCC rules, walk through our Captor double-wall SPCC 40 CFR 112 compliance guide to document the containment volume correctly. For the pad, size the 76 x 76 bearing area for the full 24,561-pound maximum load with our concrete pad sizing framework.
