The Chem-Tainer 102 Gallon Open Top Batch Storage Tank (SKU TC2745AA) is a cylindrical, natural white polyethylene tank built for batch mixing and open-access storage - the kind of work where you add ingredients on the fly, watch levels by eye, and dip or draw straight from the top. It stands 45 inches tall on a 27-inch diameter, occupying a 27 x 27 inch square footprint, so it tucks into a tight floor area while giving you 102 gallons of working volume. The open top makes it the right pick when a sealed, fitting-driven vessel gets in the way of how you actually run the batch.
Will it work for your application?
This is a 102-gallon cylindrical open top tank: 45 inches high, 27-inch diameter, on a 27 x 27 inch square footprint. The load numbers matter more than the gallons when you plan the foundation:
- Full of water: ~851 lb
- Max rated contents (1.9 SG): ~1,616 lb
- Footprint: 27 x 27 in
That 1.9 specific gravity rating means the tank is built to hold contents up to 1.9 times the weight of water, so the same 102 gallons of a heavier liquid can push the rated contents weight toward 1,616 pounds. That headroom is what you want for dense slurries, brines, or heavy batch mixes rather than a tank stressed at its limit. To confirm 102 gallons matches your throughput and turnover, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit. The technical drawing on this page shows the verified dimensions and profile.
Fittings, fill, and draw
This open top tank has no factory-installed outlet or bulkhead fitting - fill, draw, and dip all happen from the top. If you need a bottom drain, a bulkhead fitting with the correct gasket can be field-installed; confirm placement and gasket material before you order. And if your batch involves slurry or solids that need full drainage, know that an open top flat-bottom tank leaves a residual heel at the floor - see our Chem-Tainer cone-bottom 30° vs 45° drainage comparison before deciding whether flat-bottom is the right geometry for your process.
The open-top tradeoff to plan around
The mistake to avoid with any white open top tank is treating the open design as an afterthought. An open top means the vessel is vented and accessible by design - good for batch work, dipping, and visual level checks - but contents are also exposed to whatever falls in, evaporates out, or freezes at the surface in cold weather. If your batch needs to stay clean or covered, plan for a separate lid or splash cover from the start. The 1.9 SG rating is generous, but confirm your liquid's actual specific gravity against that number; running a dense load past the rating is the kind of error that shortens a tank's life. Storing water or a light solution? This rating gives wide safety margin. Eyeing something denser than 1.9 SG, or want a sealed closed-top vessel instead? Call 866-418-1777 and we'll match you to the right tank. For outdoor or cold-climate installs, our guide on freeze-protection engineering for cold-climate service walks through keeping stored water usable through a freeze.
Foundation and placement
At 27 x 27 inches, the footprint is compact, but a full tank concentrates real weight on a small area. Set it on a level, continuous surface that supports the loaded weight without flexing. Our concrete pad sizing guide for above-ground polyethylene tanks covers the ACI framework for sizing a pad to the load. If this tank feeds a grey-water, rainwater, or HVAC condensate reuse setup, the water reuse tank topology guide shows where an open batch tank fits in a staged storage train.
