Chem-Tainer 75 Gallon 20 Degree Plastic Cone Bottom Tank with Poly Stand

The Chemtainer 75 Gallon 20 Degree Cone Bottom Tank with Poly Stand (SKU TC3140JP) is built for chemical dosing and batch work where full drainage matters.The 20-degree cone bottom empties cleanly through its 1.5" outlet, and the included poly stand holds the cone off the floor so you can plumb the drain and mount a valve.Molded from natural white polyethylene with a 1.5 specific gravity rating, it stands 40" tall on a 31" diameter footprint, weighs 70 lb empty, carries an 8" fill lid, and is FDA approved.The natural white translucency lets you eyeball the level without a gauge.

Will it hold your batch

Sizing is where cone-bottom buyers get surprised, so run the numbers before you order.Filled with water this 75 gallon tank carries roughly 626 lb; at its 1.5 SG rating a full chemical load can reach about 938 lb of contents.All of that weight rides on the poly stand and your slab, so confirm both are rated for it.Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity and weight to your process, and see the technical drawing on this page for the cone angle, outlet, and stand geometry.For the same cone-bottom-with-poly-stand platform in larger volumes, our 175 gallon, 300 gallon, 310 gallon, and 550 gallon buyer's guides walk through the same decisions.

Chemical compatibility

This tank is polyethylene rated to 1.5 specific gravity.The resin is recorded as HDLPE with a question mark, so confirm HDLPE versus XLPE with us before committing it to chemical service — the two differ on stress-crack resistance, and if your chemical is an oxidizer such as Sodium Hypochlorite or Hydrogen Peroxide, resin type matters.Compatibility below comes from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific.The tank's max operating temperature is not published on this listing, and every rating here assumes ambient conditions, so confirm your exact chemical, concentration, operating temperature, and the fitting and gasket materials with us before you order.

DEF (32.5%) and Urea Solution (50%) are comfortably within spec — both need only a 1.5 SG tank, well under this tank's 1.5 rating.Note DEF calls for 316SS fittings with EPDM gaskets, not PVC.Other chemicals this 1.5 SG tank handles, with the chart's specified fitting and gasket materials: 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 Ozonated Water (up to 10 PPM, PVC, EPDM).Match the fitting and gasket to the chemical, not just the tank.

The mistake to avoid

Do not put a high-specific-gravity chemical in a 1.5 SG tank.Heavier fluids need the 1.9 SG version, and most also need a different gasket than EPDM: Sulfuric Acid (98%, CPVC + Viton), Hydrochloric Acid (37%, PVC + Viton), Sodium Hypochlorite (<16.5%, PVC + Viton), Hydrogen Peroxide (50%, PVC + Viton), Phosphoric Acid (85%, PVC + Viton), Peracetic Acid (30%, 316SS + Aflas), Ferric Chloride (50%, PVC + EPDM), Ethylene Glycol (100%, PVC + EPDM), and Potassium Hydroxide (saturated, PVC + EPDM).The 1.5 SG tank is a different fitting and gasket build, not a drop-in.Check the full Chemical Compatibility Database before you buy.
