DOUBLE-WALL TANKS

Twin Tanks' revolutionary Double Containment System is designed to alleviate the ever-changing environmental and safety concerns regarding bulk chemical storage and containment for the 21st century.

Twin Tanks' unique tank-in-a-tank design enables users and specifiers to incorporate advanced performance and safety features on a bulk handling system, which provides total containment protection. Twin Tanks' double-wall construction is complete enclosed so that external matter, such as dust, rain and snow is prevented from collecting in the outer containment tank.

Besides delivering unparalleled performance benefits, Twin Tanks' Doublewall Systems also contribute to your company's bottom line by significantly reducing installation and procurement cost. Most assemblies can be shipped fully assembled on either a standard or wide load flatbed trailer, which reduces comparable costs by an average of 35 percent.
