Foldable tanks type R/TR and R2/TR, with pillow-like shape, are made with polyesther fabric coated on both faces with plastomers suitable to the liquid to be contained. These tanks are suitable to contain and transport various liquids like: 1. drinking water, industrial water and slightly concentrated acid or alkaline solutions (type R/TR), 2. fuels (type R2/TR).
Tanks are complete of a harnessing set to fix them to the transport vehicle. Their use is particularly indicated when liquid transport by means of conventional tanks is not convenient.
