The Chem-Tainer 37 gallon polyethylene rectangular open-top tank is a compact open tank built for water storage, batching, and staging where you need easy top access and a footprint that tucks into tight spaces. Thirty-seven gallons is the nominal brim-full rating, so plan for some freeboard below the rim for your actual working level - that leaves room to fill, carry, or mix without slosh-over. Full to the brim, this tank holds roughly 309 pounds of water, so the pad, shelf, or stand under it only needs to carry a few hundred pounds - a manageable load for most benches, platforms, and skids.
Will it work for your job?
This is a rectangular open-top design, which makes it straightforward to fill, scoop, mix, dip, or draw from the top without fighting a small threaded opening. The open top also makes cleanout and inspection simple, since you can see and reach the full interior, and the rectangular shape uses floor and shelf space more efficiently than a round tank of the same volume. That is why buyers searching for an open top tank, a rectangular open top tank, or a general open tank reach for this format for wash stations, parts rinsing, small batch water, and secondary staging. One thing to plan for up front: this tank has no pre-installed outlet or drain bulkhead, so it is a top-access fill with manual or pumped withdrawal rather than a plumbed gravity-drain vessel. For the exact outside footprint and wall height, see the technical drawing on this page and confirm it against your available space or containment area before you build the platform.
Sizing and planning
If you are deciding between this and a larger or smaller open-top, run your numbers through our Tank Sizing Calculator and review the Tank Sizing Guide so you match capacity to your real draw and refill cycle rather than over- or under-buying. If the tank will sit on a poured slab, our guide to concrete pad sizing for above-ground polyethylene tanks walks through sizing the pad to the load.
