The double-walled tank provides 110% secondary containment of the inner container’s total capacity to eliminate the risk of spills and contamination. Internally baffled to prevent the surge of fuel during transport, the 10TCG has DoT approval for transportation of diesel fuel, unlike traditional fuel tanks. This gives the unit the versatility to be deployed to remote locations while full of fuel as well as the ability to be removed from a site with fuel still inside. The Transcube 10TCG has a capacity of 264 gallons.
