MNP Series Tanks, made of Steel, have an internal lining of virgin polypropylene and a chlorobutyl membrane, certified by the FDA. The membrane is fixed to the tank wall thanks to a Steel ring. A Bronze valve, sealed with a plug and an “OR” ring, prevents air from escaping.

The external coating of MNP Series Tanks, with almond-colored polyurethane paint on an epoxy base, provides hundreds of hours of protection against UV rays and aggressive environments such as saline.
