Chem-Tainer 100 Gallon 20 Degree Plastic Vertical Open Top Cone Bottom Tank with Poly Stand

The Chemtainer TC3048AP is a 100-gallon open-top cone-bottom tank with a 20-degree cone and a matching poly stand, built for chemical batching, mixing, and full-drain metering where you need every last gallon to evacuate through the cone instead of settling on a flat floor.It stands 48 inches tall on a 30-inch diameter footprint, weighs 87 pounds empty, and is molded from polyethylene rated to a 1.5 specific gravity.The open top with an 8-inch lid gives you room to charge, inspect, and clean.

Will it work for your process?

This is a vertical open-top cone-bottom tank sized at 100 gallons on a poly stand, so plan your outlet plumbing and drain clearance under the cone before install.The polyethylene wall carries a 1.5 specific gravity rating, meaning it is engineered for liquids up to 1.5 times the weight of water.Water alone fills out to about 834 pounds, but at the full 1.5 SG rating the contents can reach roughly 1,251 pounds.That number, not the 834-pound water figure, is the load path to design around.Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 100-gallon working volume and headspace match your batch.Buyers cross-shop this as a 100 gallon chemtainer vertical open-top cone tank, and the 30-inch diameter footprint keeps it compact for tight mixing rooms.

Chemical compatibility

This tank is polyethylene with a 1.5 specific gravity rating.Its resin is listed as HDLPE but not yet confirmed, so before any chemical service confirm HDLPE versus XLPE (cross-linked) for your application, since that choice affects chemical resistance.The compatibility below is cross-referenced from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; it is a working reference pending Chemtainer resin confirmation.For acids and hypochlorite especially, call 866-418-1777 to confirm resin and chemical before you order, and verify your exact chemical, concentration, temperature, and fitting and gasket materials.

At this tank's 1.5 SG rating, the chart supports service for Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM).DEF (32.5%, 316SS, EPDM) and Urea Solution (50%, PP/PVC, EPDM) each need only a 1.5 SG tank, so they clear this 1.5 rating with headroom.Match your fitting and gasket materials to the chemical, and cross-check every selection against our Chemical Compatibility Database.

Other chemicals are compatible with this resin chemistry but demand a higher specific-gravity tank than this 1.5 SG unit provides.The wall's SG rating, not the fitting, is the hard gate here: swapping a gasket or fitting will not make this tank safe for them.If your process involves Hydrochloric Acid (37%), Sulfuric Acid (98%), Hydrogen Peroxide (50%), Sodium Hypochlorite (<16.5%), Hydrofluoric Acid, Hydrofluosilicic Acid, Phosphoric Acid (85%), Peracetic Acid, Ferric Chloride, Ferric Sulfate, Ethylene Glycol, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Thiosulfate, or Zinc Orthophosphate, step up to a 1.5 SG-rated tank.Several also require Viton or Aflas gaskets and CPVC or 316SS fittings rather than the EPDM/PVC these lighter services use.Call 866-418-1777 to get that spec'd before you order.

The mistake to avoid

The trap on a 1.5 SG open-top cone tank is under-building the support.Skeptical buyers see "100 gallons" and plan for 834 pounds of water, but at the full 1.5 SG rating the poly stand and your floor both have to carry roughly 1,251 pounds with margin.The second trap is loading a heavier or more aggressive chemical than the wall is rated for.Confirm your chemical's required specific gravity against this tank's 1.5 rating first, settle the HDLPE-versus-XLPE resin question, then match fitting material (PVC, PP, CPVC, or 316SS depending on the chemical) and gasket (EPDM, Viton, or Aflas) to the OEM chart rather than to whatever hardware is on the shelf.Check the technical drawing on this page for the cone and stand geometry before you set your plumbing.
