The ACO double wall storage tank addresses all environmental and safety concerns and feature self-supporting, space saving designs. The Open-Top Outer Containment configuration for the double wall storage tank is also available.
ACO’s molding process provides uniform sidewalls and domes that eliminates the problem of domes collapsing. Our Double-Wall storage tank is designed with wall thicknesses equal to or greater than that required by ASTM D-1998 standards. By calculating the wall thickness at the bottom of each tank where hoop stress is greatest, we then produce uniform thickness throughout the entire wall. This allows for a more uniform cure with less stress, resulting in greater strength in the top portion of the tank, an area of vital importance when securing seismic or wind-load restraint systems.
The double wall storage tank provides an optimal protection against hazardous chemical spills into the environment. Inner tank dome overlaps outer tank sidewall to prevent rainwater, snow and debris from entering into the containment basin. Our ability to Heat Trace and insulate make these tanks perfect for temperature sensitive chemicals. Molded-in lifting lugs and upper fitting flats are standard. All double wall storage tanks are designed with wall thicknesses equal to or greater than that required by ASTM D-1998 standards. Double wall tanks can be customized by adding Seismic zone 4 or 120 MPH wind load tie down assemblies, leak detection, ultrasonic level indicators, and ladders.
The new double wall storage tank system provides primary and secondary containment in one space-saving integral unit.
This 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.
Inner tank dome overlaps outer tank sidewall to prevent rainwater, snow, and debris from entering secondary containment, making system ideal for outdoor storage of chemicals.
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.
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.
Available with heat tracing and insulation for use with temperature sensitive chemicals.
The double wall storage tank is available in natural color, or blue, green, gray, or black for no extra charge. Custom colors available upon request.
