The Chem-Tainer 90 Gallon PE Cylindrical Open Top Tank (SKU TC2448AA) is a tall, compact-footprint storage vessel for operations that need vertical water capacity without spreading across the floor. At 48 inches tall on a 24 x 24 inch footprint, this cylindrical open top tank holds 90 gallons in a single column, useful where floor space is tight but headroom is available. It is molded in natural white polyethylene, so you can read the liquid level through the wall at a glance, and the open top makes filling, dipping, manual dosing, and cleanout straightforward.
Will it work for your job?
Full of plain water, the tank carries roughly 751 pounds of contents, and the stand or platform you set it on has to take that load on a 24.0 x 24.0 inch base. Because the footprint is narrow relative to the height, give this tank a level, fully supported surface; a partial or rocking base concentrates stress at the bottom of a tall, slim cylinder. The 48-inch column is rated to a 1.9 specific gravity, the highest-density rating Chem-Tainer offers on this body. In structural terms that means the polyethylene shell is built to carry contents up to roughly 1,426 pounds, about 1.9 times the 751 pounds of plain water it holds, so you have real headroom when storing water or heavier light-duty mixes. For matching the column to your actual fill cycle and refill rate, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Reading the drawing and planning the install
This tank ships as a bare open-top cylinder, with no factory fittings, bulkheads, or gaskets specified. Any outlet, lid, float, or pump mount is a field add you spec yourself, so see the technical drawing on this page for the open-top diameter and overall dimensions before you order brackets or a containment ring. Confirming that opening matters if you plan to drop in a pump, float, or mixer. If this tank is going on a pad or elevated stand, our guide on concrete pad sizing for above-ground polyethylene tanks walks through supporting a loaded vessel correctly, and for rural water-storage and fire-reserve setups the fire-water reservoir design guide covers freeze protection and reserve sizing. Teams running grey-water, rainwater, or condensate capture will find this size slots into a larger train described in our industrial water reuse tank topology guide.
The mistake to avoid
The most common error with a tall, open top cylinder like this is supporting it on its outside diameter or a ring instead of under the full base. Tall slim tanks want continuous bottom support; set it on a flat, level, full-contact surface, not a stand that only catches the rim. The other thing to watch is that this is an open top tank, built for atmospheric storage and access, not for sealed or pressurized service, so do not adapt it for a closed system. Specs you may see this listed under include cylindrical open top tank, white open top tank, and open tank.
