The 4100 Gallon 45 Degree Plastic Vertical Cone Bottom Tank from Snyder Industries is a 1.5 specific-gravity, full-drain vessel built for chemical batching, mixing, and complete discharge of solution. Molded in white High Density Linear Polyethylene, it stands 197 inches tall on a 90 x 90 inch footprint and holds 4,100 gallons. The 45-degree cone empties cleanly, which is what makes this a true cone bottom tank rather than a flat-bottom vertical tank that leaves heel volume behind. Because the cone discharges below the base, the tank is not free-standing — plan a cone stand or support structure into the install.
Will it work for your process?
The number that governs everything here is the 1.5 specific gravity rating — it tells you how heavy a liquid the wall thickness is engineered to carry. Use these four figures to size your cone stand, anchor pad, and any seismic or wind calc:
- Full water weight (SG 1.0): 34,194 lb
- Max rated contents weight (SG 1.5): 51,291 lb
- Footprint: 90.0 x 90.0 in
- Overall height: 197 in
If your chemical is denser than 1.5 SG, this tank is the wrong size class and you need a 1.9 SG vessel instead. Cross-check your batch volume and density against the Tank Sizing Calculator and the Tank Sizing Guide before you order. Fitting locations, cone angle, and dimensions are detailed on the technical drawing on this page.
Chemical compatibility
This is an HDLPE tank rated to 1.5 specific gravity. At that rating, the chemicals below are compatible at the listed concentrations when paired with the correct fitting and gasket materials, per the OEM chemical-resistance chart. Every chemical in this 1.5 SG group uses EPDM gaskets; always confirm against the concentration- and temperature-specific listing for your exact service:
- 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
DEF (diesel exhaust fluid) at 32.5% is a frequent use for a cone bottom tank this size — note it calls for 316SS fittings, not PVC. Several other common chemicals are heavier than this tank is rated to hold and require a higher 1.9 SG vessel instead, not this one: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Those higher-SG services also change the fitting and gasket spec — for example sodium hypochlorite, the acids, and hydrogen peroxide call for Viton gaskets, sulfuric acid needs CPVC fittings, and peracetic acid needs 316SS with Aflas. Confirm your chemical, concentration, and temperature in the Chemical Compatibility Database before specifying.
The mistake to avoid
The single most common error on a cone bottom tank this size is matching the tank to the chemical by name instead of by specific gravity. A 1.5 SG tank handles the dilute acids and salts listed above, but if your solution exceeds 1.5 SG the wall is underbuilt for the hydrostatic load and you must step up to a 1.9 SG tank with the heavier fitting and gasket spec noted above. The second mistake is treating the resin as fully verified: this listing carries an HDLPE designation, so confirm the resin grade for your specific chemical service before committing.
