The Chem-Tainer 85 Gallon PP Cylindrical Open Top Tank is a natural white polypropylene batch and process vessel built for operators who need an open-top tank they can fill, mix, and empty by hand or by pump without wrestling a fitted lid. Standing 32 inches tall on a round 28-inch by 28-inch footprint, this cylindrical open top tank holds 85 gallons and keeps a clear line of sight to the liquid at all times. That open format is exactly why buyers reach for a white open top tank, so before you commit, work through the three things that decide whether it fits: how it works, how it ships, and the one mistake to avoid.
Does it work for your setup?
Filled with water, this tank carries roughly 709 pounds. Spread over its ~5.4 square foot footprint, that is about 130 pounds per square foot of bearing pressure on whatever it sits on, so size the pad or stand for that load, not just the total weight. Run your own liquid level and batch volume through the Tank Sizing Calculator, or read the Tank Sizing Guide if you are choosing between capacities. The open top makes it a straightforward pick for hand-batching, rinse stations, and gravity draw-off where you want to see the level directly.
Siting and fittings
An open-top cylindrical tank wants a flat, fully supported base: the round bottom should rest on a continuous surface, not span a gap or sit on rails. Setting it on concrete? Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework. This model ships without pre-installed fittings, so any bulkhead outlet or drain is added to suit your plumbing. When you add one, land it on a flat, unsupported section of wall rather than the radius, and use a gasket rated for both polypropylene and your stored fluid at service temperature.
How it ships and the mistake to avoid
This tank moves by LTL freight, quoted live to your ZIP. It typically ships from West Babylon, NY (Hanford, CA also produces this line), so your freight cost depends on which plant serves your area. Pull a real number with the Freight Cost Estimator or call 866-418-1777. The mistake to avoid: this open tank carries no potable or NSF-61 certification in our data and does not seal, so confirm your contents are compatible with polypropylene at your temperature and never treat the open format as closed storage. Confirm fit and freight up front and this 85-gallon open top tank drops straight into service. Questions on siting or fittings? Reach us at 866-418-1777.
