The Chem-Tainer 55 Gallon Open Top Batch Storage Tank (SKU TC2236AA) is a cylindrical, open-top polyethylene tank built for batch mixing, transfer staging, and general water storage where you need full top access. At 36 inches tall on a compact 22 x 22 inch footprint, it holds 55 gallons in natural white polyethylene so you can read fill levels through the wall. The open top makes it easy to add product, agitate a batch, clean out between runs, or dip and dispense by hand. Chem-Tainer molds this model at several US plants, so a stocking location near you is the rule rather than the exception.
Will it work for your job?
Filled with water, this tank carries about 459 pounds, so size your stand or pad for that load plus the empty tank. The polyethylene wall is rated to a 1.9 specific gravity, the heaviest content density the tank is built to hold, which gives you a maximum rated contents weight near 872 pounds. Rated to 1.9 specific gravity, nearly double the density of water, the same tank handles heavier brines, slurries, and concentrated water-based contents that lighter commodity open-tops cannot. Water sits at 1.0, so you have real headroom for water duty. The 22 x 22 inch footprint drops cleanly onto a small concrete pad or platform, and the open-top cylindrical shape fits an open tank, open top tank, or white open top tank role for batch and storage work. For a 55 gallon storage tank in a tight space, this is a straightforward fit. To confirm the height, diameter, and wall detail before you build a stand, see the technical drawing on this page, and run your numbers through our Tank Sizing Calculator or the Tank Sizing Guide if you are still settling on capacity.
What to get right before you order
Two things matter most on an open-top batch tank. First, this is an open vessel with no sealed lid, so it is meant for batch and storage duty, not for pressurized or fully closed service. As listed, it ships with no factory-installed fittings or gasketed outlets; if you need a drain or a plumbed outlet, call 866-418-1777 and we will confirm a fitted configuration before you order. Second, watch your content density against that 1.9 specific gravity rating. Water sits well within margin, but if you are staging a heavier water-based mix, confirm its density stays inside the rating before you fill. This tank is sold for water and general batch and storage duty; it is not certified or rated here for specific chemical service, so verify chemical compatibility before storing anything other than water. Mounting on a flat, fully supported surface protects the wall and base over the life of the tank; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the support detail.
