Double Wall Tanks


Captor Double Wall Containment

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

Captor's unique tank-in-a-tank design enables users and specifiers to incorporate
advance performance and safety features on a bulk-handling system, which provides
total containment protection. Captor's double wall construction is completely 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, Captor Containment Systems also
contribute to your company's bottom line by significantly reducing installation and procurement
cost. Every Captor is shipped fully-assembled on either a standard or wide load flat bed trailers,
which reduces comparable costs by an average of 35 percent.

Dual containment Tank (DCT) Systems

Snyder's latest product innovation, double wall DCT tanks range from 15 gallons up to 500 gallons, provide a secondary containment solution in one integral space saving unit.

The smaller design configurations are ideal for commercial "Day" tank system requirements, and can be used in conjunction with Snyder's extensive line of larger double wall Captor Double Wall Containment Systems.
