The Chem-Tainer TC3660AB is a 260-gallon open top batch storage tank molded in polypropylene, standing 62 inches tall on a 40-inch outside diameter base. Because the tank_type is a cylindrical open top, that 40 x 40 inch footprint is round, not square - a 40-inch diameter wall - so size your pad or stand for a circular base. The open top gives you full overhead access for manual fill, batch mixing, hand-add of materials, and reading the liquid line directly from above, which is why crews reach for an open tank instead of a closed vessel when a process needs to be loaded, stirred, or checked by eye. If you are comparing this to a closed white open top tank or a fitted storage tank, the trade-off is access versus containment.
Will it work for your application?
Plan around the real load. At 260 gallons of water this tank carries roughly 2,168 lbs when full, so the pad, floor, or skid underneath has to be rated for that weight on the 40-inch round footprint, not just the empty tank weight. If your batch fluid is heavier than water - anything above roughly 1.0 specific gravity - the 2,168 lb full-water figure rises proportionally, so re-rate the pad accordingly and run the numbers through the Tank Sizing Calculator. See the Tank Sizing Guide for matching capacity to your batch cycle. The white wall resists algae growth, and the open top lets you read the level directly from above without a sight gauge. Mounting it on a level, fully supported surface is essential - open top tanks rely on continuous base contact, so a concrete pad sized for the load keeps the wall from distorting under a full charge; our guide on concrete pad sizing for above-ground tanks walks through the framework.
The mistake to avoid
This is a polypropylene open top tank, not a fitted, closed storage vessel. As shipped it has no factory bulkhead fittings or outlets in its spec - it is a batch vessel meant to be loaded and worked from the top, with any drain or outlet added in the field to suit your process. Confirm the technical drawing on this page for exact wall and base dimensions before you build a stand or cut a fitting, then match any aftermarket bulkhead to the polypropylene wall: a PP or poly bulkhead body with an EPDM or Viton gasket sized to the wall thickness shown on the drawing. Treat the open top as the working access point - it is not a sealed tank, so it is not the right choice where you need vapor containment or a pressure-rated lid.
Freight
The specs list New York as a state of record, but this tank ships by LTL freight from the Hummelstown, PA plant - that PA plant is the fulfilling origin, quoted live to your ZIP. There is no flat "delivered" figure because the cost depends on your distance, access, and delivery type. Get an exact number in seconds with the Freight Cost Estimator, or call 866-418-1777 and we will quote it with you. For storage trains that combine multiple feeds, the industrial water reuse tank topology guide covers how open top batch tanks fit into a multi-stage layout. Ready to spec it? Run your ZIP through the Freight Estimator or call 866-418-1777 to lock in your open top storage tank.
