The Chem-Tainer 75 Gallon 60 Degree Cone Bottom Inductor Tank (SKU TC3343JC) is a steep-cone polyethylene tank built for batching, mixing, and full-drain dispensing where you cannot leave product sitting in the bottom. The 60-degree cone is the aggressive-drainage geometry: it self-empties solids and slurries that a shallower 30 or 45 degree cone would hold as a residual heel, which is exactly why operators reach for an inductor cone tank for chemical make-down and metering duty. It is molded in natural white polyethylene rated to 1.5 specific gravity.
Will this cone bottom tank work for your job?
Sizing is about weight, not just volume. Here are the numbers you need to design the support structure:
- Capacity: 75 gallons
- Height: 43 in
- Footprint: 33.0 x 33.0 in
- Filled with plain water: about 626 lb
- At full 1.5 SG rating: roughly 938 lb of contents
Your stand, ring, or cone-support structure has to carry that loaded weight plus the tank itself, because a cone-bottom design puts the entire mass on the support rather than a flat slab. Run your fill height and product weight through the Tank Sizing Calculator or the Tank Sizing Guide before you build the stand. The natural white wall lets you eyeball the level, and the steep 60-degree cone is the differentiator for clean draining when you are inducting dry chemical into solution. For how cone angle changes drainage rate and residual heel, see our comparison on 30 vs 45 degree cone-bottom drainage, and the cone-bottom inductor tank buyer's guides cover fitting and support choices for adjacent sizes. Dimensions and connection points are detailed on the technical drawing on this page.
Chemical compatibility
This tank is molded in polyethylene and rated to 1.5 specific gravity. The exact resin grade is not confirmed in our data, so confirm whether it is HDLPE or XLPE before committing to chemical service. All compatibility below references the OEM chemical-resistance chart, which is concentration-specific and temperature-specific, so verify your exact operating concentration and temperature against it before ordering fittings or gaskets. A common make-down duty for this size is DEF (Diesel Exhaust Fluid) at 32.5%, which this tank handles with 316SS fittings and EPDM gaskets.
Chemicals this 1.5 SG tank handles at the listed concentrations, with the recommended wetted fitting and gasket materials:
- Acetic Acid 60% — PP/PVC fittings, EPDM gasket (details)
- Aluminum Sulfate 50% — PVC fittings, EPDM gasket (details)
- Calcium Chloride 40% — PVC fittings, EPDM gasket (details)
- DEF (Diesel Exhaust Fluid) 32.5% — 316SS fittings, EPDM gasket (details)
- Ferrous Sulfate 20% — PVC fittings, EPDM gasket (details)
- Magnesium Chloride 30% — PVC fittings, EPDM gasket (details)
- Sodium Carbonate 30% — PVC fittings, EPDM gasket (details)
- Urea Solution 50% — PP/PVC fittings, EPDM gasket (details)
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gasket
One mistake to avoid: do not run a heavier chemical in this 1.5 SG tank. Many common process chemicals require a higher-rated 1.9 SG tank, and several oxidizers and strong acids also need Viton or Aflas gaskets rather than EPDM. Those needing the 1.9 SG version include Sulfuric Acid (CPVC/Viton), Hydrochloric Acid (PVC/Viton), Hydrofluoric Acid (PP/PVC/Viton), Hydrofluosilicic Acid (PP/PVC/Viton), Phosphoric Acid (PVC/Viton), Hydrogen Peroxide (PVC/Viton), Sodium Hypochlorite (PVC/Viton), Peracetic Acid (316SS/Aflas), Ferric Chloride (PVC/EPDM), Ferric Sulfate (PVC/EPDM), Ethylene Glycol (PVC/EPDM), Propylene Glycol (PP/316SS/EPDM), Potassium Hydroxide (PVC/EPDM), Potassium Carbonate (PVC/EPDM), Polyaluminum Chloride (PVC/EPDM), Sodium Bisulfate (PVC/PP/EPDM), Sodium Bisulfite (PVC/PP/EPDM), Sodium Thiosulfate (PVC/EPDM), and Zinc Orthophosphate (PP/316SS/EPDM). If your application involves any of these, ask us about the 1.9 SG version rather than forcing this tank past its rating. Cross-check your specific chemical, concentration, and temperature in the Chemical Compatibility Database.
Freight and ordering
This inductor cone tank ships LTL freight from the Chem-Tainer plant in Merced, CA, with the rate quoted live to your ZIP code. Because cone-bottom tanks carry their load on a stand, plan your support structure before delivery. Get your freight cost up front with the Freight Cost Estimator, or call 866-418-1777 and we will confirm fitting materials, the resin grade for your chemical, and freight to your address.
