The Chem-Tainer 65 Gallon PE Cylindrical Open Top Tank (SKU TC2240AA) is a 65-gallon polyethylene open-top vessel that stands 40 inches tall on a compact 22 x 22 inch footprint, stocked at our California and Pennsylvania plants and shipped from whichever is nearer your ZIP. If you searched for a white open top tank, an open tank for batching, transfer, or holding, this is a natural-white cylinder sized to fit through tight aisles and under low ceilings while still holding a useful volume. Here is how it works, how it ships, and the one decision to get right before you buy.
Will it work for your job?
The body is molded from polyethylene in natural white, which lets you see the fluid level through the wall - genuinely useful on an open-top tank where you are watching a batch or a fill. At 40 inches tall and 22 inches in diameter, full of water (specific gravity 1.0) the tank carries about 542 pounds, so plan a flat, fully supported surface that can take that load plus the tank. The tank is rated to a 1.9 specific-gravity ceiling, which works out to a maximum contents weight of about 1,030 pounds - so you can store fluids up to nearly twice the weight of water in the same 65-gallon volume, useful for brines, mild concentrates, or solids-laden water. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 65-gallon working volume matches your fill-and-draw cycle before ordering.
The open-top format and what to plan around
This is an open-top cylindrical tank, so it has no sealed lid in the spec - that makes it easy to fill from above, stir, scoop, or drop in a pump or mixer, but it also means it is not a closed pressure or sealed-storage vessel. No factory outlet or bulkhead is listed in the spec either; if you need a bottom drain, plan to add a bulkhead fitting and gasket sized to your line. For an above-ground install, set it on a solid pad; our guide on concrete pad sizing for above-ground polyethylene tanks walks through getting the base flat and fully bearing so the wall is not stressed. You can also confirm exterior dimensions against the technical drawing on this page.
The one mistake to avoid
The most important thing to check is the specific gravity of what you intend to store. This tank carries a 1.9 SG rating, so it has real headroom over water - but if your fluid is heavier than 1.9 SG, this is the wrong tank, and you should step up to a higher-rated body. Match the SG of your contents to the 1.9 rating, support the full 22 x 22 inch footprint, add your own outlet fitting if you need bottom draw, and you are within design intent. If you are unsure which body suits a heavier fluid, call 866-418-1777 and we will point you to the right one.
