General Information

HASSCO’s Contained Tank is a dual wall tank that meets all secondary containment requirements without having vacuum monitoring. Best suited for applications where continual monitoring may not be ideal and applications where tanks might be moved from site to site. These tanks are industry proven, and are the latest, easiest way to store various fresh fuels. All HASSCO tanks are phosphate washed prior to applying a high build metal treatment and two top coats of enviro-smart water based paint. Other coating options such as epoxy and powder are available upon request.
