The Chem-Tainer 55 Gallon Open Top Batch Storage Tank is built for open-access mixing and batch water storage where you need to reach in to stir, dip, sample, or pour. It stands 36 inches tall on a compact 22 x 22 inch footprint, molded in polypropylene and finished in black. The cylindrical open-top form gives you a fully unobstructed opening for manual batching, and the tight footprint tucks it into a corner, onto a pad, or beside a process line without eating floor space.
Will it work for your batch or storage job?
This is a 55 gallon open top tank in the classic cylindrical storage-tank shape. Filled to the top with water it carries roughly 459 pounds, so plan the supporting surface for that loaded weight and keep the 22 x 22 inch footprint fully supported on a flat, level base. Because the top is open rather than sealed, this tank is meant for batch storage and mixing at atmospheric conditions, not for pressurized or fully closed service. If you are matching tank volume to a fill schedule or a mixing cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you settle on a size.
Polypropylene, black color, and the open-top design
The tank is molded from polypropylene. The ANSI / NSF 61 reference here applies to the polypropylene resin, not to a model-level certification of this specific tank, so confirm your own approval path if the job requires listed potable equipment. Note that the color is black: that light-blocking wall suppresses algae growth and adds UV resistance for outdoor placement, which is a different choice than the natural or white walls usually picked for potable water. There is no drilled fitting in this open-top configuration, so liquid goes in and comes out over the open top by hand pour, dip, or pump-out. For an open batch tank, that unobstructed top is exactly the feature that makes hand-mixing, sampling, and manual charging simpler than a closed, ported drum.
Siting and pad support
Set an above-ground polypropylene tank on a surface that carries the full loaded weight without flexing. Our guide on concrete pad sizing for above-ground poly tanks lays out the framework for a stable base, and if you are aggregating rainwater, grey-water, or process water into banded storage, the industrial water reuse tank topology guide covers how a tank like this fits a larger storage train.
