General Information

HASSCO’s Contained Tank is a dual wall tank that meets all secondary containment requirements without vacuum monitoring. Best suited for applications where vacuum monitoring may not be ideal or applications where tanks might be moved from site to site. These tanks are industry proven and are the latest, most straightforward way to store various fresh fuels. All HASSCO tanks are phosphate washed before applying a high build metal treatment and two topcoats of enviro-smart water-based paint. Powder coatings available.
