Large Secondary Containment Double Wall Polyethylene Containers from Assmann Provide Capacities from 150 to 6550 Gallons

Large Secondary Containment Double Wall Plastic Containers from Assmann Provide Capacities from 150 to 6550 GallonsThis polyethylene storage tank system consists of a primary inner tank and a secondary, locked-on outer tank with a capacity of 120% of the inner tank, exceeding EPA standards.

  • The inner tank dome or our plastic storage tank overlaps outer tank sidewall to prevent rainwater, snow, and debris from entering secondary containment, making system ideal for outdoor storage of chemicals.
  • Our Double Wall Storage Tanks provides individualized secondary containment that, when placed with other tanks in large containment areas, prevents cross-contamination, and eliminates possible dangers of commingling of reactive chemicals.
  • Small footprint saves space, while portability assures convenient system relocation.
  • Our polyethylene double wall storage tanks provides individualized secondary containment that, when placed with other tanks in large containment areas, prevents cross-contamination, and eliminates possible dangers of commingling of reactive chemicals. Standard lifting lugs and specially designed indentations in the lower sidewall minimize inner tank movement during transport and installation.
  • Wide range of fittings and accessories to meet your specifications for all of our polytanks.
  • Available with heat tracing and insulation for use with temperature sensitive chemicals.
  • Double Wall Tanks are available in natural color, or blue, green, gray, or black for no extra charge. Custom colors available upon request.

Assmann Corporation advises that using its Double Wall Tank system with a bottom sidewall fitting may not meet local codes for secondary containment, as tank contents could escape containment area in the event of fitting damage. Assmann also recommends that its Double Wall Tanks be fitted with a top suction line and foot valve to provide constant flow to the pump.
