Double Wall Storage Tanks and Secondary Containment Systems Provide Protection Against Hazardous Chemical Spills
Double wall tanks (IMT) provide the best 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 (large tanks only) and upper fitting flats are standard. Molded-in lower fitting flats, along with a sturdy Assmann designed bottom outlet, reduce the cost of expensive double wall outlets. Assmann large double wall tanks are available in capacities from 150 to 8850 gallons, small double wall tanks are available in capacities from 20 to 405 gallons.
All double wall 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 tank ladder assemblies.
