The Chem-Tainer 270 gallon rectangular open top tank is a polyethylene reservoir for water-based batch mixing, parts washing, secondary capture, and open-access storage where you need to dip, drain, or stage liquid without working around a closed dome. Filled with water it carries roughly 2,252 lb, so the flat rectangular base it sits on is the single biggest thing to plan for. The open top gives full reach into the tank for cleaning, level checks, manual additions, and pump or mixer placement, and the rectangular footprint packs more usable volume into a tight floor space than a round tank of the same capacity. This is a straightforward open top rectangular tank for crews who want a durable vessel they can see into and reach into.
Will it work for your application
This is a 270 gallon polyethylene tank in an open top rectangular format. It ships as a bare open-top vessel with no factory outlets, bulkhead fittings, or gaskets, so plan any drain or pump feed as a field-installed penetration with an appropriate bulkhead fitting and gasket. Open top tanks are built for atmospheric, vented service, so use this one for storage and process work that does not need a sealed lid. It is rated for water and water-based process work; for any chemical service, confirm specific gravity and resin compatibility before you fill it. Exact outside dimensions and the top-opening layout are on the technical drawing on this page and are not duplicated in this listing, so confirm them against your space before ordering. If you are choosing between sizes or footprints, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide so capacity and footprint match what your space and process actually need.
How it ships
This tank ships LTL freight from Chem-Tainer's West Babylon, New York plant, quoted live to your ZIP code. A 270 gallon rectangular tank is a sizable freight item, so cost depends on your destination and delivery conditions.

What to get right before you buy
The most common mistake with an open top rectangular tank is the foundation. Because that 2,252 lb load is spread across a flat rectangular base rather than a round one, the entire footprint has to be continuously supported and level; a high spot, a soft edge, or an unsupported corner concentrates stress on the wall and floor of the tank. Set it on a flat, level, fully bearing pad sized to the complete base. If you are building a concrete pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework. The second thing to confirm is fit: measure your doorway and the path to the install spot against the dimensions on the technical drawing before the truck arrives, since a rectangular open top tank is bulky to maneuver.
