Chem-Tainer 15 Gallon Plastic Open Top Batch Storage Tank with Lid

The Chemtainer 15 Gallon Open Top Batch Storage Tank (SKU TC1519AA) is a compact cylindrical polyethylene vessel built for small-batch mixing, rinsing, and short-term holding where you need fast access from the top. At 17 inches in diameter and 20 inches tall, it sits on a 17-inch round footprint, so it fits on a bench, a cart, or a corner of a process line without eating floor space. The natural white polyethylene wall lets you read fluid level at a glance, and the removable 8-inch lid keeps debris out between batches while leaving the full open top available when you need to reach in, stir, or drop in a mixer.

Will it work for your batch process

This is a 15-gallon working tank with an empty weight of 8 lb, so one person can lift it, reposition it, and drain it by hand. Full of water it carries 125 lb, so size the shelf or stand under it for that loaded figure, not the empty weight. Spread across the 17-inch round base that is roughly half a psi of bearing pressure, so any flat bench or pad handles it. As an open-top design it is not a sealed, pressurized, or transport tank — it is a stationary batch and storage vessel with no pressure rating and no bottom outlet listed here. Rated service temperature runs up to 120°F / 48°C, so keep contents inside that band, and confirm the diameter, height, and lid layout against the technical drawing on this page before you build in a stand or agitator bracket.

Certifications and materials

The molded polyethylene body is FDA Approved and carries NSF/ANSI 61 — the two marks water-service buyers filter on for potable and rinse-water work. Those certifications, plus the clean natural-white wall for visual level checks, are what make this a defensible choice for a water batch or rinse station rather than a generic utility pail.

Sizing it into your line

Fifteen gallons is a true small-batch size, so match the tank to your actual draw-down per cycle rather than oversizing. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm the working volume and the loaded weight the tank puts on its base. If you are searching by the usual terms — a 15 gallon Chemtainer open top batch tank with lid — this is the unit that comes up, and the open top plus removable 8-inch lid is what separates it from a closed vertical tank.

The mistake to avoid

The most common error on an open-top batch tank is treating it like a sealed process vessel. With no pressure rating and no outlet listed, plan for top access and manual or pumped draw rather than a plumbed gravity drain unless you add fittings yourself. Stay within the 120°F limit, and confirm your chemistry is water-service before you commit — this is set up as a water batch tank, not a heavy-chemical vessel.
