Dualline Double Wall Tank’s strong, durable, quality construction is designed for the containment of all chemicals rated for contact with polyethylene. Dualline™ tanks are freestanding double wall vertical tanks with a flat bottom for indoor or outdoor stationary applications. Double wall construction provides containment in the event the inner or primary tank is compromised. AN EPDM elastic seal is standard and seals the primary tank to the secondary tank to prevent dirt and moisture from entering the containment space between tanks.

Elliptical Tanks can be selected for stationary or transportable (non DOT approved) applications both indoors and outdoors. The elliptical tank lowers the center of gravity to enhance stability and visibility. The tanks feature a standard 2-1/2” collection sump on the bottom for full drain out. An 8-1/2” deep sump option is available on five sizes. Sump is located directly under the lid on standard tanks, but a center sump option is available on tanks from 500-1250 gallons. These tanks require the bottom to be fully supported with a cradle for use. The tanks are manufactured from medium-density polyethylene with U.V. stabilizers and are designed for containment of liquids of up to 1.7 specific gravity. Tank walls are translucent for level viewing and equipped with gallon indicators.

Feed carts come equipped with a polyethylene feed container with a capacity of 3.5 bushels. The steel base comes assembled with rubber wheels that can be upgraded to the deluxe model.
