Round Horizontal Tanks are selected when transportable (non DOT approved) containment is required for indoor or outdoor applications. Tanks require skids and bands to support the round bottom. All tanks are equipped with drain out sumps. Tanks are manufactured from medium-density polyethylene with U.V. inhibitors and designed for containment of liquids of up to 1.7 specific gravity. Tank walls are translucent for level viewing and equipped with gallon indicators.
