The Snyder Industries 3600 Gallon Black HDPE Cone Bottom Tank is a 1.5 specific-gravity cone bottom tank built for bulk chemical batching, full-drain mixing, and dosing applications where the entire contents need to flow out under gravity. It stands 125 inches tall on a 102 by 102 inch footprint and holds 3,600 gallons. Molded in black polyethylene to shield contents from UV and light, this is a Snyder cone bottom tank engineered for industrial chemical service when paired with a properly rated stand.
Will it work for your chemical?
The tank carries a 1.5 specific gravity rating, which sets the hard ceiling on what you can store: the chemical's specific gravity at your operating concentration and temperature must fall at or below 1.5. Full of water (SG 1.0) the contents weigh 30,024 lb; loaded to the 1.5 rating they reach 45,036 lb. Locate your chemical's specific gravity on that 30,024-to-45,036 lb band and you have the rated load your structure must carry. Those two numbers, the 102 by 102 inch footprint and the 45,036 lb rated load, are exactly what a stand and pad must be specced to. A cone bottom tank must sit in a matching stand that supports the cone and the full rated weight, never directly on the ground. For matching geometry to a stand, work through the Cone Bottom Tank Stand Compatibility Matrix and confirm capacity with the Tank Sizing Calculator and Tank Sizing Guide. Dimensional detail is on the technical drawing on this page.
DEF and urea solution: spec 316SS fittings
This is a common cone bottom platform for diesel exhaust fluid and urea handling. DEF at 32.5% and urea solution at 50% both fall under the 1.5 SG rating, but DEF is the one chemical on this tank's compatible list that calls for 316 stainless steel fittings with EPDM gaskets rather than the PVC or PP used elsewhere. Spec PVC on a DEF outlet and you have a mis-spec that shows up as corrosion and contamination down the line, so match DEF fittings to 316SS exactly as listed.
Chemical compatibility
This tank is molded in HDLPE polyethylene at a 1.5 specific-gravity rating. The resin designation ends in a question mark in our data, so before committing it to chemical service, confirm with us whether your specific unit is HDLPE or XLPE (cross-linked) at 866-418-1777, since the two resins resist different chemicals. Compatibility below is drawn from the manufacturer's chemical-resistance chart and is concentration- and temperature-specific, so verify your exact conditions against that chart before ordering.
At its 1.5 SG rating, this tank handles 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 fittings, EPDM gaskets). Every compatible chemical here uses EPDM gaskets, and fittings are PVC or PP across the board except DEF's 316SS, so match the fitting and gasket material to the chemical exactly as listed.
Chemicals that need a higher-SG tank
Several chemicals are storable in polyethylene but exceed the 1.5 SG ceiling of this unit and require a 1.9 specific-gravity tank instead. If your application involves 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, or zinc orthophosphate, call us before ordering so we can spec the correct 1.9 SG tank. The gasket material also changes for several of these: hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, and sulfuric acid call for Viton rather than EPDM; peracetic acid calls for Aflas; and sulfuric acid runs CPVC fittings. The full Chemical Compatibility Database lets you check your chemical, concentration, and the required SG, fitting, and gasket before you buy.
This cone bottom tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, with the cost quoted live to your ZIP code through our Freight Cost Estimator. Because it ships freight, your freight cost depends on distance, accessorials, and jobsite access, so run your ZIP for an exact number or call 866-418-1777 to confirm fittings, stand pairing, and the resin question above before you order. For containment and instrumentation planning, the Snyder Captor Plus 110% Containment vs UL-142 / SPCC comparison, the tank level gauge selection guide, and the bulk polyethylene tank labeling and signage compliance guide walk through the codes and instrumentation that surround a chemical install like this one.
