The ECO-TANKVAN design is covered by U.S. and Foreign Patents and is an innovative food-grade bulk liquid collapsible tank unit that easily converts a tank trailer into a standard trailer. The ECO-TANKVAN eliminates the costs and environmental effects associated with return trips taken by empty tank trailers after offloading their liquid cargo by allowing the same truck to carry a full packaged cargo load on the return leg.

Tank Mode

ECO-TANKVAN tank mode

The tank unit is semi-permanently installed and is compatible with any van trailer or inter-modal container. In the tank mode, the tank unit is rigid (not a bladder).

Upon emptying of the liquid cargo, the tank collapses and retracts up to the trailer ceiling. The tank unit is compact, resulting in minimal space loss inside the trailer.

Economic competitiveness and environmental sustainability are two key competing business drivers. Transporting liquid bulk cargo is an economic necessity while trucks contribute about five percent of the greenhouse gases produced in this country.

Addressing the impact that trucking has on our environment is our responsibility and obligation. The ECO-TANKVAN can help you achieve two goals - reduce your transportation costs and reduce your company's carbon footprint.
