This 84-gallon polyethylene open top tank is a Ronco-branded storage vessel built for batch mixing, short-term storage, and process staging where you need easy top access to add, monitor, or draw down contents. At 84 gallons in a polyethylene body, it fills the gap between small drums and full bulk storage — a practical size for a rinse station, a batch tank on a line, or a staging vessel where an open top makes loading and cleanout simple.
Will this open top tank work for your job?
Filled with water this tank carries roughly 701 pounds of liquid, so the pad or platform under it has to support that load plus the tank itself. Size the stand and any secondary containment to the full-water figure, not the empty weight — an under-planned base is the most common mistake with a batch tank this size. If you are matching tank volume to a process flow or a fill schedule, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide first, so 84 gallons is the right size once you leave yourself freeboard at the top.
Open top means plan your access and drawdown
An open top storage tank gives you full overhead reach for mixing, sampling, and cleaning, but it also leaves the contents exposed — plan for a cover, screen, or lid if you are storing anything that needs protection from debris, evaporation, or the weather. This is a water-service storage tank; keep it to the batch storage, rinse, and process-staging duties it is built for. For foundation planning on an above-ground poly tank, our guide on concrete pad sizing for above-ground polyethylene tanks walks through supporting the full loaded weight correctly.
The mistake to avoid
This open top tank ships without factory-installed fittings, so don't assume it drains or plumbs like a closed vertical tank. If you need a bottom outlet or a specific drawdown point, plan and locate that fitting before installation rather than cutting into a filled tank later. Confirm your intended contents suit standard polyethylene water storage, and check the technical drawing on this page for the tank's dimensions so it fits your footprint and any containment curb.
