Agrico Plastics | Double Wall Tanks

Double-walled plastic tanks are specially designed for storing chemicals. They are equipped with an internal tank that contains the liquid and an external secondary tank that serves as a recovery basin in the event of a leak. They are used in particular for the storage of chemical or corrosive substances, which are dangerous for workers or the environment.

FDA compliant material for food use
Resin meets NSF/ANSI Standard 61 requirements for potable water
Maximum operating temperature: 120°F / 49°C
Double-walled tanks have no drain, inlet or vent; they are sold separately depending on the chemical compatibility of the liquid to be contained.
All bulkhead fittings must be installed on top of the tank, so as not to pierce the outer wall of the retention basin.
The tanks have no level graduation, since it is impossible to see the level, because there is no contact between the liquid and the external wall of the tank.
It is very important to validate the chemical compatibility of the liquid to be contained with that of the tank.
The tanks are used for the containment of liquids with a relative density of up to 1.9.
A range up to a density of 2.2 is also available on request.
Always validate the relative density of the product to be stored with that of the tank.

These plastic tanks can be installed directly on the ground, on a firm and flat base, so they do not require any additional support.
They are perfect for storage, all substances that are corrosive or dangerous for the environment, which, in the event of spillage, could endanger the health and safety of workers or harm the environment.
The tanks are used for the containment of liquids with a relative density of up to 1.9. A range of up to 2.2 is also available on request.
They are manufactured according to ASTM standards and meet local and federal regulations required for the protection of the environment against leaks.
Double-walled plastic tanks meet safety standards that require an external tank with a recovery capacity of 120% of the internal tank.
This type of plastic tank takes up significantly less space than a standard rectangular retention basin, so it is preferred to save floor space.
