The Snyder Industries 2000 Gallon Captor Double Wall Tank is a black crosslinked linear polyethylene (XLPE) containment tank built to ASTM standards, rating a 2000-gallon working capacity at a 1.9 specific gravity. It stands 103 inches tall on a 102 by 102 inch footprint in a double-wall, tank-within-a-tank configuration where an outer wall surrounds the primary vessel for secondary containment. If you searched "Snyder double wall tank" or "XLPE 2000," this is the unit.
Will it work for your install?
The XLPE resin and 1.9 SG rating mean this tank is engineered to hold heavier-than-water contents, not just plain water. Filled with water alone it carries 16,680 lb; at its maximum rated 1.9 SG contents it is built to carry 31,692 lb. That loaded weight drives your pad design and anchoring more than anything else, so size your foundation to the full figure, not the empty shell. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the working volume and freeboard you actually get after thermal expansion is accounted for.
Standard fittings on this Captor are a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. The 15-inch-access manway and fittings serve the primary tank, so coordinate every outer-wall penetration against the technical drawing on this page before you set valves, vents, or fill lines, or you risk compromising the secondary containment. The 18-inch threaded/vented fitting handles the tank's breathing during fill, draw, and the thermal expansion you size freeboard around.
Sizing and ASTM discipline
A 2000-gallon nameplate is not 2000 gallons of usable headroom once you reserve freeboard. For the engineering behind that, read Snyder Captor double-wall freeboard sizing per ASTM D1998, and if your site falls under spill-prevention rules, the Captor SPCC 40 CFR 112 compliance walkthrough shows how an integral double wall maps to containment requirements. Operators concerned with long-term durability should also review where premature failures originate at the vapor-saturated headspace, and for fire-protection storage the NFPA 22 fire-water reservoir design guide covers cold-climate freeze protection.
The mistake to avoid
Do not assume the 1.9 SG rating clears every fluid. The rating tells you how heavy a liquid the tank can structurally hold, but chemical compatibility is a separate question driven by the resin and your specific fluid, concentration, and temperature. For any chemical service, verify your fluid against the OEM chemical-resistance chart before committing. Spec the gasket on the 18-inch vented fitting and the manway cover to your fluid, because those two interfaces, not the XLPE wall, are where most chemical-service failures start. Plumbing a corrosive into the wrong gasket is a far more common failure than overloading the wall.
