Our innovative SAFE-Tank® double wall storage and containment system, the "tank within a tank", provides customers with a leveraged investment that offers peace of mind and environmental care. Our high density crosslinked polyethylene SAFE-Tank® double wall system alleviates the need to build large, high-maintenance concrete containment areas. In the event of a spill, the SAFE-Tank® double wall system's all-in-one design features a protected containment area that will safely isolate reactive chemicals, protect your employees from harm, and protect you from environmental remediation, all within the footprint of a standard vertical tank.

Available with the OR-1000 system

Advantages of the SAFE-Tank® double wall tank system

  • Provides 110% secondary containment.
  • Will equalize the liquid and allow the chemical to be continually used until it is convenient to repair the tank.
  • Is ideal for chemicals like sulfuric acid that can have dangerous exothermic reactions to water.
  • Eliminates the expense, cost and maintenance of secondary concrete containment.
  • Minimizes the system’s footprint by providing secondary containment in a more compact way.
  • Adding a bellows transition fitting will maximize your SAFE-Tank® system's performance.

Choose the factory closest to you for the best freight rates. If a tank from a more distant factory is required for volume or dimensions, we may be able to equalize freight to make it the same as another choice. We have trucks that go between factories and other arrangements. Please inquire through your salesperson for details.
