The Chem-Tainer 105 Gallon Open Top Batch Storage Tank (SKU TC3624AA) is a cylindrical open-top vessel built for batch mixing, dosing, and short-term storage where you need to reach into the tank from above. It stands 24 inches tall on a 36-inch diameter footprint, so it tucks under low ceilings and fits a standard 48 x 40 pallet while still holding a full 105 gallons of working volume.
Will this open top tank work for your job?
This is a Natural White polyethylene open tank with a 2.0 specific gravity rating, which is heavier-duty than the 1.5 SG common on open-top batch tanks. That 2.0 rating means the wall is built to carry contents up to twice the density of water, so it suits brines, slurries, and dense batch media that a lighter open top cannot. Filled with plain water, expect roughly 876 pounds of total load; loaded to its full SG rating, the tank is engineered to carry contents up to about 1,751 pounds. Plan your pad and any stand for the heavier of those two numbers. The open top makes it easy to add product, agitate a batch by hand or with a top-mounted mixer, and clean out between runs. With a 36 x 36 inch footprint, a cluster of these batch tanks lines up neatly along a wall or on a mixing bench. See the technical drawing on this page for the exact dimensions before you build supports or size a containment area, and run your volume through the Tank Sizing Calculator or review the Tank Sizing Guide if you are deciding between this and a taller storage tank.
Freight and lead time
This tank ships LTL freight from the Chem-Tainer plant in West Babylon, New York, the nearest named shipping point for this model. Because open-top tanks are light for their size, freight is rated on dimensions as much as weight, so the quote depends on your delivery ZIP and whether you have a dock or need a liftgate. Get an exact number before you order with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you.
The mistake to avoid
The most common error with an open top tank is treating it like a closed storage tank. An open top is not sealed against splashing, evaporation, contamination, or freeze in cold climates, and the unsupported rim is not a structural ledge, so do not rest a lid, mixer bracket, or load on it without proper support. This model is listed with no factory outlets or bulkhead fittings, so if you need a bottom drain you will spec a fitting and gasket separately or choose a tank built for it. An open top also leaves a residual heel that will not gravity-drain, so if you need to empty fully and handle solids, our guide comparing Chem-Tainer cone-bottom tanks at 30 degrees versus 45 degrees shows the self-draining alternative. If you are weighing this batch tank for a larger reservoir or fire-water role, the fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection for cold-climate service, the concrete pad sizing guide for above-ground polyethylene tanks walks through pad design for the loaded weight, and the industrial water reuse tank topology guide covers where open and closed storage tanks each belong in a treatment train.
