ACO’s full line of Double Wall Tanks provide the best protection and peace of mind for chemical storage applications. Consists of a primary inner tank and secondary containment tank, with a capacity of 120% of the inner tank.

  • Excellent chemical and corrosion resistance and low temperature impact
  • Durable one-piece seamless construction
  • Built to ASTM specifications
  • UV stabilized for sunlight protection
  • Narrow diameters for space saving in-plant use
  • Rated for liquids with a specific gravity (density) of up to 1.5 (1.9 and 2.2 tanks are also available)
  • Manufactured from HDPE or XHDPE (cross-linked polyethylene)
  • The HDPE resin complies with FDA and is listed NSF 61 for potable water applications
  • Fittings are not supplied on tanks unless requested
  •  
  • Bottom Thru-Containment Outlet and Leak Detection Device available (optional)
  • We recommend double wall tanks be supplied with a top suction line to avoid any holes below the water line.

DMT Double Wall Tanks

Inner tank dome overlaps outer tank sidewall to prevent rainwater, snow and debris from entering into the containment basin. Narrow design is ideal for space saving. Molded-in lifting lugs (large tanks only) and upper fitting flats are standard. Molded-in lower fitting flats can accommodate our sturdy optional bottom outlet.
