Elliptical Cradle Tanks can be selected for stationary or transportable (non-DOT approved) applications: hauling / storage of fresh potable drinking water, grey water, liquid compatible chemicals and liquid fertilizers. Elliptical tanks feature a low-profile design and a low center of gravity for excellent visibility in the field and increased stability when towed. A deep sump permits complete drainage and the tanks feature an 8" or 16" fill-opening. All Elliptical Cradle Tanks require the bottom to be fully supported with a steel cradle for use. Tanks are manufactured from Food Grade Polyethylene with U.V. inhibitors and designed for containment of liquids up to 1.7 specific gravity. Tank walls are translucent for level viewing and equipped with gallon indicators. Steel cradle, bands and accessories sold separately.
