Chem-Tainer 200 Gallon 20 Degree Plastic Vertical Open Top Cone Bottom Tank with Poly Stand

The Chemtainer 200 Gallon 20 Degree Open Top Cone Bottom Tank (SKU TC3175AP) is built for chemical batching and full-drain dosing where you need every last drop out the bottom.It stands 75" tall on a 31" diameter footprint, weighs 105 lb empty, and carries a 1.5 specific gravity rating in polyethylene.The 20-degree cone bottom seats in the included poly stand, and the 16" open top gives you clear access for mixing, manual charging, and cleanout.This is a chemtainer cone bottom tank sized for 200-gallon process work, not water storage - the cone drains at the tip, so confirm your outlet and bulkhead spec by phone before ordering, since fittings are configured to your job.

Will it hold your process weight?

Plan your stand pad and anchoring around loaded weight, not gallons.Filled with water this tank carries roughly 1,668 lb; at its full 1.5 SG rating the contents can reach about 2,502 lb.The cone-and-stand design puts that load through the legs, so a level, rated surface matters, and the technical drawing on this page gives you the exact height and footprint to lay out your pad.If you are still sizing the batch against freeboard and mixing headspace, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit.For the full walkthrough on cone-bottom-with-stand selection, the 175 gallon cone bottom buyer's guide and the 300 gallon guide cover the same tradeoffs at neighboring sizes.

Chemical compatibility

This is a polyethylene tank rated to 1.5 specific gravity, per the Snyder Industries OEM chemical resistance chart.That chart is concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and fitting and gasket materials before service.The tank resin resolves to HDLPE with a question mark in our data - confirm HDLPE versus XLPE with us before you fill it, because that distinction changes chemical service.One clean rule to remember: every chemical that falls within this tank's 1.5 SG rating runs EPDM gaskets with PVC or PP fittings.

Chemicals the 1.5 SG rating covers on the OEM chart include Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), Ferrous Sulfate (20%), Magnesium Chloride (30%), and Sodium Carbonate (30%) - all PVC fittings, EPDM gaskets.DEF (32.5%) and Urea Solution (50%) rate at only 1.5 SG, so this 1.5 tank comfortably exceeds their requirement; note DEF specifically pairs 316SS fittings with EPDM gaskets.Ozonated Water is compatible up to 10 PPM on PVC fittings and EPDM gaskets - it's the one item on this list without a linked datasheet, so confirm your ozone concentration with us before service.

The mistake to avoid: assuming this 1.5 SG tank covers the heavier acids and oxidizers.It does not.Nineteen chemicals on the OEM chart require the 1.9 SG rating instead - among them Sodium Hypochlorite, Sulfuric Acid (98%), Hydrochloric Acid (37%), Ferric Chloride, Hydrogen Peroxide (50%), Phosphoric Acid, and Ethylene Glycol - and several of those swap to Viton gaskets.Stepping up to a 1.5 SG tank is the honest fix, not overfilling this one; we stock them, so call 866-418-1777 to spec the right one.Cross-check your exact chemical in our Chemical Compatibility Database first.
