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.
