Double Wall Tanks

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

• 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.
