The 275PE is the big-batch tank of Ronco's open-top cylinder family: 275 gallons in a 42 x 48 inch molding, the widest mouth and the largest volume in this run of the line. This is the tank shops graduate to when batch sizes outgrow everything else - bulk solution make-up, large-parts soaking, staging process liquid for an entire line rather than a single station.
Its proportions favor access over height: at 48 inches tall the rim stays workable while the 42 inch diameter swallows parts, baskets, and mixer heads that narrower cylinders refuse. The molded polyethylene body weighs 100 pounds empty and carries the same chemical service range as the rest of the family - Ronco has been molding PE process tanks in Tustin, California since 1974, and this is the flagship of the open-top cylinders.
At this volume, plumbing is not optional - nobody bails 275 gallons. Ronco installs fittings per order, spin-welded or threaded at the locations you mark: bottom drain for gravity dumps, side outlet for a pump loop, overflow if the process wants one. Print the technical drawing below, lay out the ports against your floor piping, and finalize with the fitting planner on this page. The matching molded cover is the natural companion - a mouth this wide collects everything when left open.
