Double Wall Tanks

220 Gallon Peabody Gemini Dual Containment Cylindrical Tank

Double Wall Tanks for Sale

Double wall tanks from 5 to 6,502 gallons that hold a leak inside a second tank, for chemical storage, chemical feed and used oil or antifreeze collection. Peabody's tank-in-a-tank models meet or exceed EPA 40 CFR secondary containment requirements.

If the inner wall ever fails, a double wall tank keeps the chemical in the outer shell instead of on your floor. We carry double wall tanks from Peabody, Chem-Tainer and Ronco, and Chem-Tainer's outer containment complies with federal regulation 40 CFR 264.193.

Applications of Double Wall Tanks

Chemical Storage

Peabody Gemini tanks mold both walls in polyethylene, with a leak detection port for an optional alarm and a pump platform on the dome. Pick a 1.5 or 1.9 specific gravity wall to match the weight of your chemical.

Chemical Feed Stations

Peabody Value-Pak systems ship the double wall tank with its lid, fittings and accessories, so it arrives ready to plumb as a feed station. Three package levels decide how much of the system comes with the tank, and we'll send the full parts list before you order. Shop tank fittings and hardware.

Tight Spaces and Outdoor Sites

Square Gemini tanks put the same containment into a square footprint that tucks against a wall or between equipment, where a round tank wastes floor space. Chem-Tainer's round double wall tanks work indoors or out, and their enclosed top keeps rain, snow and debris out of the containment space.

Used Oil and Antifreeze

Service bays collect used oil and antifreeze in Gemini tanks with a black inner tank inside a translucent outer shell, so you can see the level and any leak at a glance. Shop waste oil tanks.

Get the Right Double Wall Tank

Already have a single wall tank? A containment basin may be all you need, so shop secondary containment systems. For a new tank, send your chemical, its concentration and its temperature with a quote request and we'll match the resin and wall.
