Infinitank Canotto Reinforced modular underground tanks

Rototec’s Infinitank and Minitank underground tanks are modular units in which a number of one-piece, linear high density 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.

Use and specifications
Modular underground tank to store drinking water, rainwater, effluent and other compatible liquids
TECHNICAL CHARACTERISTICS

Rototec’s Infinitank and Minitank underground tanks are modular units in which a number of one-piece, linear high density 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 is a totally atoxic material that does not foster the growth of algae in fluids contained in the tanks, making them ideal for storing potable water and other liquid foodstuffs. 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. 

NB: Rototec modular tanks must always be installed underground. 

TOTALLY VIRGIN: no regenerated materials are used. 

COMPLETELY NON-TOXIC: also suitable for use in contact with drinking water or water that is to be treated for drinking (see D.O.P.) 100% recyclable: fully respects the environment. 

ANTI-ALGAE: with anti-UV additives to screen out sunlight and prevent the formation of algae and structural weakening. 

INERT: in the presence of chemical and physical agents in the atmosphere and chemicals in the soil. 

STRENGTH: capable of withstanding considerable temperature variations of from – 20 to + 80°C.
