The 2500 Gallon 30 Degree Crosslink Cone Bottom Tank (SKU SII-5110000N42) is a Snyder Industries cone-bottom vessel molded in cross-linked polyethylene (XLPE) and rated to 1.5 specific gravity, which is what makes it a chemical-service tank rather than a plain water tank. The 30 degree cone-bottom geometry drains completely, so it suits batching, mixing, and full-discharge dosing where you do not want product pooling on a flat floor. Footprint is 90.0 x 90.0 inches with an overall height of 125 inches, so plan your pad and overhead clearance accordingly. Like most who shop this size, you may also be comparing it against 15 degree cone and poly-stand configurations.
Does it fit your job?
At 2500 gallons, a full charge of plain water weighs about 20,850 lbs, and at the tank's maximum 1.5 SG rating the contents can reach roughly 31,275 lbs. That means a full 1.5 SG charge puts close to 31,275 lbs across a 90 x 90 inch footprint, so engineer the pad and stand for that load, not for the lighter water weight. A 30 degree cone needs a properly engineered stand to carry the tank and keep the cone supported. The factory fittings shown on the technical drawing on this page include a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access for entry, inspection, and cleaning. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the working volume and weights against your process before you commit.
Chemical compatibility
This tank is XLPE rated to 1.5 SG. At that rating it handles a range of chemistries at the concentrations below, provided fittings and gaskets are matched correctly. Always verify your exact chemical, concentration, and temperature against the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific.
- Acetic Acid 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate 50% - PVC fittings, EPDM gaskets
- Calcium Chloride 40% - PVC fittings, EPDM gaskets
- DEF 32.5% - 316SS fittings, EPDM gaskets
- Ferrous Sulfate 20% - PVC fittings, EPDM gaskets
- Magnesium Chloride 30% - PVC fittings, EPDM gaskets
- Sodium Carbonate 30% - PVC fittings, EPDM gaskets
- Urea Solution 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
A few common chemistries are not a fit for the 1.5 SG version and require a higher 1.9 SG tank instead: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid (Viton gaskets), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, and Sodium Thiosulfate. If you plan to store one of those, step up the SG rating rather than forcing this tank. Browse the full Chemical Compatibility Database to confirm your fitting and gasket selections.
The mistake to avoid
The single most expensive error on a chemical cone-bottom tank is matching the SG rating to water instead of to your product. This tank is rated to 1.5 SG; heavier chemistries demand a 1.9 SG tank, and running the wrong rating shortens tank life and risks failure. The second is pairing the wrong fitting and gasket material with your chemical, since the resin can be fine while an incompatible fitting or gasket fails first - note DEF specifically requires 316SS fittings, not PVC, per the chart. Match both the SG rating and the fitting and gasket materials to your exact chemical before you order.
