The Chem-Tainer 55 Gallon Open Top Batch Storage Tank (SKU TC2236AB) is a cylindrical open-top vessel molded from polypropylene in white, measuring 22 inches in diameter and 36 inches tall on a compact 22 x 22 inch footprint. The full 22-inch open rim is your access dimension: it gives you room to drop in a mixer or agitator, scoop by hand, or pump from above for batching and dosing work. If you have searched for an open top tank, an open tank, or a 55 gallon polypropylene storage tank for batch work, this is the size that drops into a tight corner without sacrificing working volume.
Will it work for your job?
This is a 55-gallon working vessel built for water and water-based batch storage. Filled to the brim with water, plan for roughly 459 pounds at full capacity. Spread across the 22 x 22 inch footprint, that is only about 1.2 psi distributed, which is trivial for a poured slab but a real point load on plywood or decking, so set it on a flat, rigid base that will not flex. If you are pouring a slab, the concrete pad sizing guide walks through how to size and reinforce the base for an above-ground tank of this weight. Not sure 55 gallons is the right batch size for your process? Run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a footprint.
Open top, polypropylene, and what to watch for
The open top means this tank is vented to atmosphere by design, so it carries no pressure or vacuum and is suited to batch mixing and short-duration storage rather than sealed or fully enclosed service. There are no factory fittings listed on this configuration, so if you need an outlet you supply the bulkhead and gasket yourself. For ambient water service, an EPDM gasket is the standard pick; plan the outlet location and size the bulkhead bore to the wall thickness at the height you choose before you drill. The most common mistake on a tank like this is treating an open-top polypropylene batch vessel as a substitute for a sealed potable or chemical storage tank. As configured here it is a batch and water-storage vessel, so match it to the way you actually work: fill, mix, draw, repeat.
Freight and how to order
