The Snyder Industries 4100 Gallon 45 Degree Cone Bottom Tank in white is a high-volume, full-drain vessel for industrial chemical batching, mixing, and storage where you need every gallon to evacuate without leaving a residual heel. Molded in High Density Linear Polyethylene (HDLPE) with a 1.5 specific gravity rating, it stands 197.25 inches tall on a 90 x 90 inch footprint and holds 4100 gallons. The 45 degree cone is the steepest standard cone angle: over a 90-inch diameter the apex drops roughly 45 inches below the sidewall, so thick or settling product self-drains faster and cleaner than it would from a 15 or 30 degree bottom. That geometry is exactly why it gets searched as a "cone bottom tank," "cone tank," or simply a Snyder "cone."
Will it work for your application?
This is a cone bottom tank, so it cannot stand on its own. It must be supported in a steel or poly stand sized to the cone, and that structure carries the full load. Plan your support around the heavier number: filled with plain water this tank carries roughly 34,194 lb of contents, but at its maximum 1.5 SG rating it is built to hold up to 51,291 lb of product. Size your stand, slab, and rigging to the 51,291 lb maximum, not the water figure, because the rated load is about 50% heavier than water and is the most common spot where structures get under-built. The cone geometry, 197-inch top access height, footprint, and discharge point at the cone tip are detailed on the technical drawing on this page. The fitting count, size, and location are not listed here, so confirm the bulkhead and outlet schedule for your chemical against the drawing or by calling 866-418-1777 before you order. The Tank Sizing Calculator and Tank Sizing Guide help you confirm this 4100-gallon size against your batch volume and turnover.
Chemical compatibility
This tank is molded in HDLPE with a 1.5 specific gravity rating, so it covers chemicals at or below 1.5 SG. Always verify against the OEM chemical-resistance chart, which is concentration and temperature specific, and match your fittings and gaskets to the chemical, not just the tank. Compatible chemicals at this 1.5 SG rating 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), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Watch the wetted-parts calls: DEF requires 316 stainless steel wetted parts, and ozonated water requires PVC with EPDM, so the wrong metal or elastomer is the most common mistake on a tank this size.
Chemicals that require a higher-SG tank
This 1.5 SG tank handles anything at or below 1.5 specific gravity; the chemicals below all need a 1.9 SG tank instead, with no in-between tier, so do not store them in this vessel. A wetted-parts rule helps here: strong acids and oxidizers require Viton or Aflas gaskets, and EPDM will fail in those services. They include Sulfuric Acid (CPVC, Viton), Hydrochloric Acid (PVC, Viton), Phosphoric Acid (PVC, Viton), Sodium Hypochlorite (PVC, Viton), Hydrogen Peroxide (PVC, Viton), Hydrofluoric Acid (PP/PVC, Viton), Hydrofluosilicic Acid (PP/PVC, Viton), and Peracetic Acid (316SS, Aflas). Others on the 1.9 SG list run on EPDM: Ferric Chloride (PVC), Ferric Sulfate (PVC), Ethylene Glycol (PVC), Propylene Glycol (PP/316SS), Polyaluminum Chloride (PVC), Potassium Hydroxide (PVC), Potassium Carbonate (PVC), Sodium Bisulfate (PVC/PP), Sodium Bisulfite (PVC/PP), Sodium Thiosulfate (PVC), and Zinc Orthophosphate (PP/316SS).
