The Snyder Industries 3900 Gallon XLPE Heavy Duty Cone Bottom Tank is built for full-drain chemical batching where you cannot leave product sitting in the bottom. Molded in crosslinked linear polyethylene (XLPE) and rated to 1.9 specific gravity, this 3,900-gallon cone tank stands 180 inches tall on a roughly 90-inch diameter, 90 x 90 inch footprint in natural white, so you can read levels through the wall. The cone bottom forces complete gravity discharge of slurries and settling chemistries that flat-bottom verticals leave stranded.
Will it work for your application
This is a high-capacity vertical cone tank: 3,900 gallons, 180 inches tall on a roughly 90-inch diameter sitting within a 90 x 90 inch footprint. Plan your support stand and ceiling clearance around that 180-inch height plus the elevation the cone requires off the ground. The 1.9 specific gravity rating is the headline spec here, and it is Snyder's heavy-duty ceiling for this line, so there is nothing denser to step up to; it means the tank wall and fittings are engineered for dense, heavy chemistries rather than water alone. Filled with water this tank carries roughly 32,526 lb; loaded to its maximum rated contents it carries up to 61,799 lb, so the slab, stand, and anchoring all have to be sized for that mass before delivery. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the cone tank and stand fit your batch volume and headroom. Because a cone bottom only drains fully when it is properly supported and level, review the Cone Bottom Tank Stand Compatibility Matrix before you order steel, and see the technical drawing on this page for dimensional detail. Outlet, fill, and vent sizing are confirmed per order, so call 866-418-1777 to match port sizes to your pump and plumbing.
Chemical compatibility
This tank is molded in XLPE (crosslinked polyethylene) and carries a 1.9 specific gravity rating, which is what lets it hold the denser solutions below. XLPE resists environmental stress cracking better than standard HDPE under aggressive chemistries; for the why behind that choice, read Snyder XLPE vs HDPE: When Crosslinking Matters. Match your fitting and gasket materials to the chemical you are storing. Compatible chemistries from the OEM chemical-resistance chart include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrofluosilicic Acid (26%, PP/PVC fittings, Viton gaskets), Magnesium Chloride (30%, PVC, EPDM), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS fittings, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Thiosulfate (40%, PVC, EPDM), and Urea Solution (50%, PP/PVC fittings, EPDM). It is also rated for ozonated water (up to 10 PPM, PVC fittings, EPDM gaskets), verified directly off the OEM chart. The OEM chemical-resistance chart is concentration- and temperature-specific, so confirm your exact concentration and operating temperature against it and check each chemical on our Chemical Compatibility Database before ordering.
The mistake to avoid
The common error on a tank this size is ordering the wrong fitting and gasket for the chemistry. Note where the chart calls for something other than the default PVC/EPDM: Hydrofluosilicic Acid needs Viton gaskets, DEF needs 316 stainless fittings, and Propylene Glycol calls for PP or 316SS. Spec the fittings to the chemical, not the other way around. The second error is treating the 1.9 SG rating as optional, the rating exists because dense chemistries load the wall far harder than water, and undersizing the stand or slab for the 61,799 lb maximum loaded weight is how cone tanks fail. For tracking and dosing those batches, the level gauge selection guide for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options.
This Snyder cone bottom tank ships LTL freight from the nearest qualifying plant, Lincoln, NE, with freight quoted live to your ZIP code. Because this is a large single-tank LTL haul, freight scales with distance, so pull a live ZIP quote from our Freight Cost Estimator before budgeting, or call 866-418-1777 to confirm fittings, stand compatibility, and chemical service before you order.
