Chem-Tainer 30 Gallon Plastic Open Top Batch Storage Tank with Cover

The Chemtainer 30-gallon open-top batch storage tank (SKU TC1829AA) is a cylindrical polyethylene vessel built for mixing, batching, and short-term water storage where you need full top access. It stands 30 inches tall on a 20-inch diameter footprint, holds 30 gallons, and has a natural-white polyethylene wall. Empty, it weighs just 13 pounds, so one person can position it on a pad or bench before filling. The open top takes an 8-inch cover, and the molded polyethylene body carries FDA Approved and NSF 61 certifications. Buyers searching for a 30 gallon Chemtainer open-top batch tank with cover will find this is the compact, hand-access format for that job.

Will this tank work for your batch?

Filled with water, this tank carries roughly 250 pounds of contents. The wall is rated to a 1.9 specific gravity, so it can safely hold denser water-based batches up to about 475 pounds of rated contents (the SG 1.9 wall ceiling, not an extra volume allowance) before you would need a heavier-wall tank. Maximum service temperature is 120 F / 48 C, so keep hot fills below that line. The 20-inch diameter footprint keeps the stand or pad compact, and the open-top format with its 8-inch cover makes it easy to add powders, agitate, or hand-dip. If you are not certain 30 gallons is the right size for your fill-and-draw cycle, run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide before you order.

The mistake to avoid

This is an open-top batch tank, not a sealed transport or pressurized vessel. The 8-inch cover sets on top; it is not a gasketed, bolt-down lid, so plan for evaporation and keep the tank stationary and upright once filled. Confirm your contents stay at or under the 1.9 specific gravity and 120 F temperature limits, and verify the level against the 30-inch straight-side wall rather than assuming headroom. Check the technical drawing on this page for exact dimensions before you build a stand or pad around it. If you are sizing water storage for a larger job, our guides on industrial water reuse tank topology and concrete pad sizing for above-ground polyethylene tanks cover the surrounding setup.
