The Chem-Tainer 670 Gallon Open Top Batch Storage Tank (SKU R367260A) is a rectangular open-top polyethylene tank built for batch storage and bulk holding where you need full top access. It measures 72 inches long, 36 inches wide, and 60 inches tall, giving you a flat 36 x 72 inch footprint that lines up against a wall or sits inside a containment curb without wasting floor space. The open top is the whole point: the full 36 x 72 inch opening lets you reach the entire 60-inch interior to manually add product, monitor levels, agitate, and clean the tank out between batches.
Will it work for your job?
This is a 670 gallon rectangular open top tank molded from natural white polyethylene and rated to a 2.0 specific gravity. That 2.0 SG rating is the standout spec, and it is unusually high for an open-top poly tank. It means this vessel carries liquids up to about 16.7 pounds per gallon, twice the weight of water, so it handles dense brines, slurries, and concentrated batch liquids that a standard 1.0 to 1.5 SG water tank cannot. In numbers: a full water fill is roughly 5,588 pounds, while the tank is rated to carry contents up to about 11,176 pounds at the 2.0 SG ceiling.
Before you place it, confirm your support surface. A full tank at the maximum rated load approaches 11,000-plus pounds, so it belongs on a level, continuously supported pad sized for that weight. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework for getting the foundation right. If you are still working out volume and freeboard, the Tank Sizing Calculator and Tank Sizing Guide help you match the tank to your batch size.
The mistake to avoid
Match the specific gravity rating to your actual liquid. The 2.0 SG rating is generous, but it is a ceiling, not a license to skip the math: know the density of what you are storing in pounds per gallon and stay inside the rating. Check it against your product's own density sheet rather than assuming. The other thing to plan for: this SKU is configured as a plain open-top vessel, with no factory-installed outlet or bulkhead in its specification. Liquid leaves the tank by pump-out or dip from the top, or you can field-install a bottom bulkhead fitting with the appropriate gasket if you need a gravity drain. Open top also means open to the environment, so account for splash, evaporation, and debris if the tank sits outdoors, and choose a closed-top tank instead wherever a sealed top is required.
Freight
This tank ships LTL freight from the Chem-Tainer plant in West Babylon, New York, the named shipping point for this SKU. Because that is the only origin, freight is a real cost driver on a tank rated to carry 11,000-plus pounds: a Northeast delivery is a short, inexpensive LTL haul, while a West or South destination carries a longer, heavier run from New York. Freight is quoted live to your ZIP rather than bundled into the list price, so set your expectations by distance from West Babylon.
