Chem-Tainer 15 Gallon 20 Degree Plastic Vertical Open Top Cone Bottom Tank with Poly Stand

The Chemtainer TC1530AP is a 15-gallon open-top cone-bottom tank molded from polyethylene and rated to 1.5 specific gravity, sitting on a matched poly stand with a 20-degree cone that drains fully to the bottom.It stands 31 inches tall on a compact 17-inch-diameter footprint, weighs 26 pounds empty, and carries a 5-inch lid opening for filling, mixing, and manual dosing.The full 20-degree cone makes it a natural fit for batching, day-tank, and gravity-drain duty where you need a small vessel to empty completely between fills.

Will it hold your contents

Sizing is about weight, not just gallons.Filled with plain water this tank carries about 125 lb; at its full 1.5 SG rating the contents can reach roughly 188 lb resting on the poly stand.Put another way, 1.5 SG means the tank tolerates a liquid about 50% denser than water, and 188 lb is the hard ceiling the stand and walls are built for - so anything heavier per gallon than 1.5 SG is a structural limit, not just a chemical-resistance question.Set it on a level, load-rated surface and support the stand feet evenly.Because it is an open-top design, plan for a cover or the 5-inch lid if the contents need protection from evaporation, contamination, or splash.Run the numbers for your own liquid with the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a fitting and stand layout.

Chemical compatibility

This tank is polyethylene rated to 1.5 specific gravity.The resin is listed as HDLPE but not fully confirmed - confirm HDLPE versus XLPE (cross-linked) before putting it into chemical service, since that choice changes what you can store.Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; verify your exact chemical, concentration, temperature, and the fitting and gasket materials before ordering.

Chemicals that suit this 1.5 SG tank include acetic acid (60%) and aluminum sulfate (50%) with PP/PVC or PVC fittings and EPDM gaskets; calcium chloride (40%), ferrous sulfate (20%), magnesium chloride (30%), and sodium carbonate (30%), all on PVC fittings with EPDM gaskets; and ozonated water up to 10 PPM on PVC with EPDM.For fluid handling, DEF (32.5%) specifically calls for 316 stainless fittings with EPDM - do not substitute PVC there - while urea solution (50%) runs on PP/PVC with EPDM.

The mistake to avoid on this tank: several common chemicals need a higher-SG vessel than 1.5 and should NOT go in this one.Sodium hypochlorite (below 16.5%), hydrochloric acid (37%), ferric chloride (50%), phosphoric acid (85%), hydrogen peroxide (50%), and ethylene glycol (100%) all call for a 1.5 SG-rated tank, usually with Viton gaskets.Two break the usual PVC/Viton pattern and are worth watching: sulfuric acid (98%) needs CPVC fittings with Viton, and peracetic acid (30%) needs 316SS fittings with Aflas.If your service is on that list, step up to a higher-SG tank rather than forcing this one.Cross-check every case against the full Chemical Compatibility Database.

Freight and how to order

This tank ships LTL freight from the nearest stocking plant - Delano, MN or the Illinois location - quoted live to your ZIP so you only pay for the lane you actually use.See the technical drawing on this page for cone and fitting geometry, get your freight number in seconds with the Freight Cost Estimator, or call 866-418-1777 to confirm resin, fittings, and stand fit before you buy.For sizing context on the larger cone-bottom-with-stand family, see our 175 gallon cone-bottom buyer's guide and 550 gallon 20-degree guide.
