LibertyCES has documented Dual Containment Tank in Acids service, including Sulfuric Acid. Wetted materials to confirm: XLPE. Documented models include Poly Processing SAFE-Tank and Snyder Captor/DCT Systems. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
SAFE-Tank explicitly ideal for chemicals with dangerous exothermic reaction to water, e.g. sulfuric acid.

SAFE-Tank's double-wall design is specifically built for chemicals like sulfuric acid that react dangerously — exothermically — with water, which means the secondary containment basin needs to stay dry in service; introducing water to a contained acid spill is itself a hazard, not just a containment nicety.
Single-wall tanks put the entire burden of containing a sulfuric acid spill on a separate concrete berm; SAFE-Tank's 110% secondary containment is molded into the tank system itself and is explicitly engineered for chemicals — like sulfuric acid — that react dangerously with water. Liberty CES defaults to dual containment on chemistries with a documented water-reactivity hazard, not just where a customer happens to request it.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
