The Chem-Tainer 575 Gallon Open Top Batch Storage Tank (SKU TC4296AA) is a cylindrical open-top polyethylene tank built for batching, mixing, and bulk water storage where you need full top access. At 96 inches tall on a 42-inch diameter (a 42 x 42-inch bounding footprint), it stacks 575 gallons of volume into a tight floor area, so it fits in narrow process bays and along walls where a wider tank would not. The open top makes it easy to add ingredients by hand, drop in a mixer or agitator, and inspect the batch without opening fittings.
Will this tank work for your job?
This is a Natural White polyethylene tank carrying a 2.0 specific gravity rating, meaning the wall is built to hold contents weighing up to twice the weight of water. Filled with plain water the tank carries about 4,796 pounds; at its full 2.0 SG rating it is rated for contents up to 9,591 pounds, which gives you real headroom for dense slurries and heavy mixed batches that lighter-rated open tops cannot handle. As an open top storage tank it ships with no molded outlets, so call 866-418-1777 to add bulkhead fittings, gaskets, and a bottom drain sized to your discharge before you order. For help confirming the 575-gallon size against your batch volume and turnover, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. Dimensional details and the wall profile are shown on the technical drawing on this page.
Sizing it into your space
The 42-inch diameter and 96-inch height are the two numbers to check first. This is a tall, slim tank, so confirm your ceiling clearance and the reach you need to load and clean from the open top. Set it on a flat, fully supported pad - a smooth concrete slab is the standard base for an above-ground polyethylene tank of this weight. Because the tank can hold up to 9,591 pounds fully loaded, size the slab for that figure, not the 4,796-pound water weight, if you plan to store dense batches. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through how to size and detail that slab so the loaded weight is carried evenly. One common use for a tank this size is fire-water and emergency reservoir storage; our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline. If instead you are aggregating grey water, rainwater, or HVAC condensate into banded storage, our industrial water reuse tank topology guide shows where an open-top batch tank fits in the train.
The mistake to avoid
Do not run a heavy-density batch in a tank rated below your contents. This open top is built to a 2.0 specific gravity, so it handles dense mixes most general-purpose open tanks cannot - but you still have to match the SG rating to what you are actually storing. If your batch runs denser than 2.0 SG, call 866-418-1777 and we will match you to a higher-SG open-top tank rated for your contents. The other common miss is the open top itself: it is a vented, non-pressure vessel, so it is not the tank for anything that must stay sealed or under pressure. Size the support, match the SG, and keep the access you bought it for.
