The Chem-Tainer 1100 gallon open top batch storage tank is a cylindrical, open-top polyethylene vessel for high-density water and process batching where you need top access for mixing, manual additions, or monitoring. The hard envelope to plan around: 90 inches tall, 60 by 60 inch footprint, 1,100 gallons, rated to 2.0 specific gravity - one of the heaviest contents ratings in the open-top class, which is why operators reach for this Chem-Tainer when an open tank has to do real work rather than just hold rainwater. Confirm the 90-inch vertical clearance plus offload headroom at your receiving point before you order; an open-top vessel needs room above the rim, not just floor space.
Will it do the job
Filled with water, this tank carries roughly 9,174 lb of contents. Sized to its full 2.0 SG rating, it can hold contents weighing up to 18,348 lb - about 16.6 lb per gallon. Check your fluid's density against that number yourself: anything heavier than 16.6 lb/gal exceeds the rating. The open-top design means you load from the top, and the flat 60 by 60 inch footprint has to bear on a level, continuously supported base rated for the full filled weight. A standalone steel stand or an undersized pad will not work - the entire bottom must sit on a flat surface. Run your batch volume and turnover through our Tank Sizing Calculator or read the Tank Sizing Guide before you lock a size, and if you are pouring a slab, the concrete pad sizing guide walks through the ACI framework for above-ground polyethylene tanks at this weight.
How it ships
This Chem-Tainer tank ships by LTL freight from the West Babylon, New York plant, quoted live to your ZIP code. An open-top 90 by 60 by 60 inch vessel cubes out before it weighs out - dimensions drive the rate, not the 9,174 lb water weight - so distance from West Babylon is the lever, and a 1,100 gallon tank can quote high if you are far from New York. Get an exact figure before you order with our Freight Cost Estimator, or call 866-418-1777 and we will quote it with you. The tank ships with the top open, so plan your receiving and offload around a tall, open vessel.
The mistake to avoid
The most common error with an open top tank rated to 2.0 SG is treating the rating as license to skip the foundation work. The rating tells you the polyethylene wall can carry contents up to twice the density of water; it does not change the fact that the full load - up to 18,348 lb - has to land on a flat, fully supported, level base. The second mistake is forgetting that "open top" means the contents are exposed: no sealed lid, no pressure, no closed headspace. If your application needs containment from debris, evaporation control, or any closed-system behavior, this white open top tank is the wrong starting point. Outlet and fitting configuration are not specified in this listing - if you need a bottom outlet or any threaded connection, confirm what this tank ships with by phone at 866-418-1777 before you buy rather than assuming one is present. If you are weighing this against a closed cone-bottom for faster, cleaner draining, the cone-bottom drainage comparison is worth a read.
