The 80 Gallon 45 Degree Cone Bottom Inductor Tank from Norwesco (part N-47190) is a closed-top, cone-bottom mixing and metering vessel built so a batch drains completely between cycles. Molded in white polyethylene rated to 1.5 specific gravity, it stands 37" tall on a 32" x 32" footprint and holds 80 gallons. The 45-degree cone drives solids and slurry to the center outlet, which is why the inductor and cone bottom tank format is specified for day tanks, polymer make-down, and chemical induction rather than flat-bottom storage. The clearest single-fluid fit at this size is diesel exhaust fluid: an 80-gallon cone inductor with 316SS fittings and EPDM gaskets is a textbook DEF make-down and dispensing vessel.
Will this tank work for your application?
Match the job to the numbers. At 80 gallons of plain water this tank carries about 667 lb of contents; at its maximum 1.5 specific gravity rating it is built to support up to 1,001 lb of contents. Use those figures to size the stand or cone-support structure, because a cone bottom tank transfers its full load to the support ring rather than a flat floor - the structure has to carry the rated weight, not just hold the tank upright. The 32" x 32" footprint and 37" height set your stand clearance and the headroom needed above the lid for filling and mixer mounting. Run your contents through the Tank Sizing Calculator and the Tank Sizing Guide to confirm volume and weight before you order, and see the technical drawing on this page for dimensional detail. One procurement note: our data does not publish a factory fitting or outlet size for this tank, so confirm the bulkhead and outlet configuration against the drawing before you plumb it.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. The resin is noted as HDLPE in our data but is not yet confirmed - verify HDLPE versus XLPE (cross-linked) with the manufacturer before placing it in chemical service, since the two resins differ in chemical resistance. Compatibility below is keyed to specific concentrations and to the fitting and gasket materials that go with each chemical; always confirm against the OEM chemical-resistance chart, which is concentration- and temperature-specific, before committing to a chemical.
At this tank's 1.5 SG rating, the following are workable at the concentrations shown: DEF (32.5%, 316SS fittings, EPDM gaskets), Acetic Acid (60%, PP/PVC, EPDM), 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 Urea Solution (50%, PP/PVC, EPDM). Ozonated Water (up to 10 PPM, PVC, EPDM) is workable too, but ozone slowly oxidizes polyethylene even at low PPM, so plan for inspection over the tank's life rather than treating it as inert service.
Several chemicals you may be considering need a heavier tank than this 1.5 SG model. 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, and Zinc Orthophosphate all call for a 1.9 specific gravity tank. If your chemical is on that list, ask us for the 1.9 SG-rated cone inductor equivalent rather than under-rating this one - call 866-418-1777. Several of those (sodium hypochlorite, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, phosphoric acid, sulfuric acid) also require Viton gaskets, and peracetic acid requires an Aflas gasket, rather than EPDM. Check every chemical against our Chemical Compatibility Database before ordering.
The mistake to avoid
The costly error on a cone-bottom chemical tank is matching the chemical to the polyethylene but ignoring the specific gravity and the gasket. This is a 1.5 SG vessel - it is not rated for the 1.9 SG chemicals listed above, and dropping a high-density chemical into an under-rated tank shortens its service life. Likewise, EPDM gaskets do not survive sodium hypochlorite or strong oxidizers per our data; those need Viton. Confirm the resin (HDLPE versus XLPE), confirm the SG rating covers your chemical, and confirm the gasket and outlet hardware before the tank is plumbed.
