Chem-Tainer 180 Gallon Plastic Open Top Batch Storage Tank

The Chem-Tainer 180 Gallon Open Top Batch Storage Tank (SKU TC3060AA) is a 60-inch-tall cylindrical open-top tank on a compact 30 x 30 inch footprint, built from natural white polyethylene for batch mixing, transfer, and storage.What sets this one apart is its 2.0 specific gravity rating: where a standard open-top tank tops out around 2.0 SG, this wall is built to carry dense batch liquids and settling slurries up to roughly 3,002 lb of rated contents.The open top makes it straightforward to add ingredients, monitor level by eye, and clean out between batches - the working pattern most people mean when they search for an open top tank or a white open top tank.

Will it work for your batch?

This is a vertical cylinder: 60 inches tall, 30 inches in diameter, on a 30.0 x 30.0 inch footprint.Plan your pad and overhead clearance around those numbers, and remember an open top tank is for ambient, non-pressurized storage - it is not sealed against vapor or spill.Filled with water the contents weigh about 1,501 lb, so the pad and any platform underneath need to carry that load plus the tank itself.Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 180 gallons matches your batch cycle and refill rate before you commit, and consult the technical drawing on this page for the as-built dimensions.

Specific gravity and what it does (and doesn't) cover

The 2.0 SG rating is the most useful number on this tank, and it is easy to misread.Water has a specific gravity of 1.0, so a 2.0 rating means the wall is engineered to hold contents up to twice the density of water - the headroom that lets this storage tank carry heavier slurries and dense batch liquids a 1.5-rated open-top should not.The mistake to avoid is treating that rating as a chemical clearance.SG governs the structural load the wall can carry, not what liquids the polyethylene will resist.Polyethylene handles many liquids but not all, and an open top is not a containment system, so verify the specific liquid against the manufacturer chemical-resistance chart - concentration and temperature specific - before storing anything other than water.

Fittings, draining, and slurry duty

This SKU ships as an open-top vessel with no factory-installed outlet or bulkhead fitting, so plan how you will fill and empty it: draw from the top, or add a bulkhead fitting and gasket sized to your plumbing for a bottom or side connection.If the liquid is anything other than water, check both the polyethylene wall and your added fitting and gasket material against the chemical-resistance chart - the gasket elastomer is often the compatibility-limiting part, not the PE.One more thing worth knowing if you are storing settling slurries: a flat-bottom open top leaves a residual heel and is harder to fully drain.If full drainage and solids handling matter for your batch, our comparison of Chem-Tainer cone-bottom tanks at 30 vs 45 degrees walks through drainage rate and residual-heel performance for a higher-spec geometry.

Freight and ordering

This tank ships LTL freight from the Chem-Tainer plant in West Babylon, NY.Because LTL pricing depends on distance and your delivery situation, freight is quoted live to your ZIP code rather than baked into the list price - get a number in minutes with the Freight Cost Estimator, or call us at 866-418-1777 and we will walk you through sizing, accessories, and the freight quote together.Planning a foundation?Our guide on concrete pad sizing for above-ground polyethylene tanks covers how to size the pad for the full water weight above.
