The Chem-Tainer 260 Gallon Open Top Batch Storage Tank (SKU TC3953AA-BLACK) is a cylindrical, black polyethylene open top tank built for batch mixing and bulk water storage where you need to reach into the vessel, add product by hand, or agitate contents. It stands 53 inches tall on a 39 x 39 inch footprint, holding 260 gallons in a compact space. As an open tank, it is made for staged storage, blending, and transfer work rather than sealed containment.
Will it work for your job?
Filled with water, this tank carries roughly 2,168 pounds. Its polyethylene wall is rated to a 2.0 specific gravity, which supports contents up to about 4,337 pounds at full 260-gallon volume. That means it can hold liquids up to twice the density of water, so plan your pad for your actual fluid, not just water. A 2.0 SG rating is real headroom over the common 1.5-SG open-tops, giving you room for dense brines and heavier-than-water batches. If you are still deciding on capacity for your process, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide to match volume, batch size, and refill cadence before you commit.
Open top design and placement
The open top gives you full access for manual charging, mixing, and inspection, which is why this black tank is a common choice as a batch stage in a larger storage tank train. Because it is open, it should sit on a flat, fully supported surface that carries the loaded weight without flex. For above-ground installs, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for a base that keeps the tank level over its life. If you are aggregating grey-water, rainwater, or process water, the guide on industrial water reuse tank topology shows how an open top batch tank fits a quality-banded storage train. Dimensional details and any molded features are shown on the technical drawing on this page.
Freight and ordering
This tank ships LTL freight, quoted live to your ZIP. It is stocked at multiple Chem-Tainer plants, so the nearest shipping point may be Albertville, AL, Hummelstown, PA, West Babylon, NY, or Keaau, HI. The Freight Cost Estimator auto-selects the closest of these plants for your accurate rate, or call us at 866-418-1777 and we will help you spec the right open top storage tank and lock in freight. One mistake to avoid: this is an open, non-pressure vessel, so it is not meant for sealed or pressurized service. Keep it in atmospheric batch and storage duty and it will serve you for years.
