INFINITANK AND MINITANK Rototec's Infinitank and Minitank underground tanks are modular units in which a number of one-piece, linear polyethylene (LLDPE) modules, manufactured using a rotomoulding process, are connected to each other to give large storage volumes. Thanks to the special pieces available (curve and Tee) the Infinitank model can be used to create tanks of various shapes, allowing the best possible use of available space. The various modules making up a tank are connected by means of a double system of bolting and electro-welding. Two modules are joined and fixed together by means of steel bolts, guaranteeing mechanical stability for the tank. Water tightness, on the other hand, is guaranteed by a special polyethylene electro-welding procedure. Polyethylene, in fact, is a totally non-toxic material and does not foster the growth of algae in the fluids contained in the tanks, thus making the tanks ideal for storing potable water and other foodstufs. Furthermore, linear polyethylene also supports sudden changes in temperature (from -20 to + 80 °C) and is inert in the presence of chemical substances in the soil. For these reasons, there are no material oxidation or corrosion problems that would prejudice the mechanical characteristics and impermeability of the tanks. Furthermore, while possessing the same characteristics as other materials (cement, fibreglass, metal), tanks in polyethylene are much lighter, and as such transport, installation and maintenance are extremely simple and economic. Finally, polyethylene tanks can be bored when the need arises, for example when connecting tanks together, installing inlet/outlet pipes, overflows, etc.
