The Chem-Tainer 1500 gallon 15 degree open top cone bottom tank is a vertical polyethylene tank rated to 2.0 specific gravity. The 15-degree sloped cone bottom keeps settling solids and slurries moving toward the outlet instead of packing into a flat floor, which matters when you are storing process chemicals that drop sediment. At 2.0 SG, this is the heaviest-duty content rating offered for this tank, so it carries denser liquids than a 1.5 SG vertical. It stands 84 inches tall on a 73 inch diameter, so plan your stand and pad around that diameter before the truck arrives. This tank is widely searched as an open top cone bottom tank, and the 15-degree slope sits at the gentle end of the cone range.
Will it work for your job?
Capacity is 1500 gallons. At full water that load is roughly 12,510 lbs, and at the maximum rated 2.0 SG contents it reaches about 25,020 lbs. Because this is a cone bottom tank, it does not sit on a flat pad on its own footprint: it has to ride in a stand sized and rated for the full loaded weight, and your pad has to carry the stand's leg loads, not a load spread evenly across the 73 inch diameter. Confirm the stand and pad rating before you specify anything else, and confirm your contents' specific gravity does not exceed 2.0, since this tank does not have a higher-SG version to step up to. For help matching this size to your volume and turnover, use the Tank Sizing Calculator and the Tank Sizing Guide.
Chemical compatibility
This is a polyethylene tank rated at 2.0 specific gravity. The resin is recorded as HDLPE in our data but is not yet confirmed, so confirm the exact resin (HDLPE versus XLPE) with us before committing this tank to chemical service. The pairings below are concentration and temperature specific, drawn from the OEM chemical-resistance chart, so match your exact concentration and operating temperature before ordering. This listing ships without fittings pre-specified, so fill, vent, level, and drain hardware must be selected and matched to your chemical's required fitting and gasket material.
Three pairings are easy to get wrong and worth calling out first: DEF at 32.5% and peracetic acid at 30% both require 316SS fittings, not PVC; peracetic acid is also the only chemical here that calls for an Aflas gasket rather than EPDM or Viton; and sulfuric acid at 98% needs CPVC with Viton, not standard PVC. The fuller compatible list for this 2.0 SG polyethylene tank includes acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), ethylene glycol at 100% (PVC, EPDM), ferric chloride at 50% (PVC, EPDM), ferric sulfate at 60% (PVC, EPDM), ferrous sulfate at 20% (PVC, EPDM), hydrochloric acid at 37% (PVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), hydrofluosilicic acid at 26% (PP/PVC, Viton), hydrogen peroxide at 50% (PVC, Viton), magnesium chloride at 30% (PVC, EPDM), phosphoric acid at 85% (PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate at 50% (PVC, EPDM), potassium hydroxide saturated (PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate at 30% (PVC, EPDM), sodium hypochlorite below 16.5% (PVC, Viton), sodium thiosulfate at 40% (PVC, EPDM), urea solution at 50% (PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water up to 10 PPM (PVC, EPDM). The mistake to avoid is ordering generic hardware and assuming it covers your chemical. Full details are in the Chemical Compatibility Database.
Top fitting layout and cone selection
Because this is an open top cone bottom tank with nothing pre-specified, where you place fill, vent, level, and drain decides whether your operation stays clean or fights cross-contamination and maintenance conflicts. Our guide on tank top fitting placement strategy walks through the layout engineering. If you are weighing cone angles against this tank's 15-degree slope, see the Chem-Tainer cone-bottom 30 vs 45 degree comparison, the 1500 gallon 45 degree cone bottom buyer's guide, and the 15 vs 30 vs 45 degree selection guide for how cone angle affects drainage rate and residual heel. Refer to the technical drawing on this page for outlet and dimensional detail.
