The Chem-Tainer 90 Gallon Polypropylene Open Top Batch Storage Tank (SKU R242436B) is a rectangular open top tank built for hands-on batch mixing and short-term holding where you need easy top access to the liquid. It measures 24 inches long by 24 inches wide by 36 inches tall, giving it a 24.0 x 24.0 inch footprint that fits on a workbench, a pallet, or a small concrete pad without eating up floor space. The body is molded in natural white polypropylene.
Will it work for your batch process?
This is a 90-gallon working vessel, and the open top is the whole point: it lets you add material, stir, sample, and clean out the tank without fighting a fitted lid. Filled with water, plan on roughly 751 pounds at capacity, so set it on a surface and structure rated to carry that load with margin. One thing to weigh up front: at 36 inches tall on a 24 x 24 base, this is a tall, narrow vessel with a high center of gravity when full, so confirm the stand and floor are level and rated to keep it stable. This shape shows up regularly as a rectangular open top tank for batch work. If you are not sure 90 gallons matches your throughput, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit. For the exact wall and rim dimensions, see the technical drawing on this page.
The mistake to avoid
An open top tank is intended for atmospheric, vented service. Do not treat it as a sealed or pressurized vessel, and do not assume a flat-lidded enclosure of the same footprint will give you the same access or the same clearances. Because no factory side fittings are listed for this unit, plan any bulkhead outlet or drain you need as field work. Match any gasket and hardware you add to the polypropylene tank wall, and confirm the placement against the wall geometry on the drawing rather than the nominal outside dimensions. If your liquid is heavier than water, the full weight climbs above 751 pounds, so re-check your stand and floor loading before filling.
