The Chem-Tainer 150 Gallon Inductor Cone Bottom Tank (SKU TC3366JC) is a 1.5 specific-gravity polyethylene tank built for batching, mixing, and full-drain dispensing of treatment chemicals. It holds 150 gallons in a 33-inch by 33-inch footprint and stands 66 inches tall, with a fully sloped cone bottom that drains to the center outlet so you are not chasing a residual heel or stuck solids at the end of a batch. As a cone bottom tank, it needs a stand or structural support to hold the cone off the ground, which keeps the bottom outlet accessible for gravity discharge or a transfer pump.
Will this tank work for your chemical and your space?
Start with weight. Filled with water (specific gravity 1.0), the tank carries about 1,251 lb. At its maximum rated contents it carries up to 1,876 lb, which reflects its 1.5 SG rating - that is the heaviest contents this tank is built to hold. Size your stand, anchoring, and floor for the full loaded weight, not the empty shell. And mind the geometry: at 66 inches tall on a 33 x 33 inch footprint, this is a 2:1 height-to-width profile on a stand, so brace and anchor it for lateral stability, not just vertical load. If you are unsure which capacity fits your process volume and headroom, the Tank Sizing Calculator and Tank Sizing Guide walk through working volume versus rated capacity. For drainage geometry, our comparison of Chem-Tainer cone-bottom tanks at 30 vs 45 degrees covers how cone angle affects drain rate, residual heel, and solids handling so you pick the right slope for your media.
Chemical compatibility
Before you rely on any compatibility data, confirm the resin. This tank is recorded as HDLPE with a question mark at a 1.5 specific-gravity rating, so confirm HDLPE versus XLPE with us before you commit it to chemical service - the two resins behave differently with certain media, and an unconfirmed resin makes every line below provisional. Then check your exact chemical against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and match fitting and gasket materials to the chemical, not just the tank.
At this tank's 1.5 SG rating, the following are compatible at the listed concentrations: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets); Aluminum Sulfate at 50% (PVC, EPDM); Calcium Chloride at 40% (PVC, EPDM); DEF (diesel exhaust fluid) at 32.5% (316SS fittings, EPDM gaskets); Ferrous Sulfate at 20% (PVC, EPDM); Magnesium Chloride at 30% (PVC, EPDM); Sodium Carbonate at 30% (PVC, EPDM); Urea Solution at 50% (PP/PVC, EPDM); and Ozonated Water up to 10 PPM (PVC, EPDM). One spec-check cue: DEF is the only one of these that calls for 316 stainless fittings - it is easy to wrongly default to the PVC the rest of these use.
Several common chemicals are NOT a fit for this 1.5 SG tank and need a higher 1.9 SG tank instead - an honest call so you do not under-spec: 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. If your chemical is on this list, call 866-418-1777 and we will spec the right higher-SG tank for it. Cross-check every detail in our Chemical Compatibility Database before ordering.
The mistake to avoid
The most common error on a cone bottom inductor tank like this one is matching the chemical to the tank but ignoring the fittings and gaskets. The bottom outlet sees the most aggressive contact and the most stress, so the fitting and gasket materials listed above - PP, PVC, or 316 stainless with EPDM gaskets for the 1.5 SG chemicals this tank handles - matter as much as the tank wall. Note that the Viton and Aflas gasket calls tied to the harsher chemicals apply to the higher 1.9 SG tank, not this one. The second mistake is reading the SG rating as a suggestion. This is a 1.5 SG tank; the 1.9 SG chemicals listed above will outpace its rating and shorten its life. Review the exact dimensions and outlet detail on the technical drawing on this page before you finalize your stand and plumbing.
