The Chem-Tainer 94 Gallon PE Rectangular Open Top Tank is a 94-gallon polyethylene rectangular open-top vessel built for batching, washdown, parts soaking, and general water storage where you need full top access to load, mix, or remove material by hand. The open top makes filling, inspecting, and cleaning straightforward, and the rectangular footprint sits tight against walls and into corners where a round tank wastes floor space. Filled with water, this tank carries roughly 784 lb, so plan your stand, pad, or platform for that loaded weight before you put it into service.
Will this open top tank work for your job?
This is a 94-gallon rectangular open top tank molded from polyethylene, sized for operations that need a wide, accessible mouth rather than a sealed, fitted vessel. If your process involves dipping, scooping, ladling, or frequent visual checks of the contents, the open top format is what you want. It ships as a bare open vessel with no factory-installed bulkhead fittings, outlets, or gaskets, so if you need a drain or outlet, budget for a field-installed bulkhead fitting and gasket kit and plan where it goes before you set the tank. The format is the same one shops look for when they search for an open tank, a rectangular tank, or simply rectangular open top storage. If you are unsure whether 94 gallons is the right working volume for your fill-and-draw cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
Set it on a base rated for the load
At roughly 784 lb filled with water (specific gravity 1.0), the pad or platform under this tank has to carry that full load distributed across the rectangular base, and a heavier-than-water fluid scales that weight up proportionally. Set it on a flat, fully supported surface and confirm your foundation against our Concrete Pad Sizing guide before the tank goes into service. This open-top format also works well as a fill-and-draw reservoir; if you are building out a private fire-protection or rural water supply, our Fire-Water Reservoir Tank Design guide walks through NFPA 22 sizing and freeze protection.
The mistake to avoid
The most common error with an open top tank is treating it like a closed, plumbed storage tank. This is an open, atmospheric vessel: it is not built to be sealed or pressurized, and an uncovered top means evaporation, debris, and splash are part of the deal unless you add your own cover. This tank is listed for water and atmospheric service, so before you put any chemical in it, verify the specific gravity and compatibility of your liquid first. If your liquid runs heavier than water or you need clean bottom drainage, a closed cone-bottom tank rated for a higher specific gravity is the better fit; our Chem-Tainer Cone-Bottom 30° vs 45° comparison covers drainage rate and residual heel. For pairing this tank into a larger reservoir or rainwater setup, our guide on industrial water reuse tank topology shows how open and closed vessels fit together in a staged storage train.
