Sottotetto tank 300 l

Above ground tank for storage of food liquids - drinking water

The Sottotetto tank is made of high-density polyethylene (LLDPE) by rotational moulding. Rotational moulding is a process of manufacturing tanks from a single piece, free of welds that could weaken the tank components and this does not cause internal stresses. The tank is made of polyethylene that is completely non-toxic and not conducive to algae growth. The tank is ideal for storing drinking water and other food liquids. The tank is resistant to temperature changes (from -20 °C to +60 °C) and to atmospheric, chemical and physical conditions. The tank is not subject to corrosion or oxidation processes, which is excellent for its tightness. The tank is lightweight, easy to transport and its installation is very simple and economical. Sottotetto tanks are non-pressurised tanks. To regulate the inflow of water, a flow regulator must be used. In our offer of aboveground drinking water tanks we also have other models such as: Jolly tanks, Cubo tanks or KiTank tanks.

  • An optional spigot hole can be provided.
  • Tanks are approved by the Polish National Institute of Hygiene (PZH).
The tanks are available in 5 colours:

  • granite (standard)
  • blue RAL 5015
  • grey RAL 7037
  • green RAL 6005
  • terracotta RAL 8004

DRINKING WATER TANKS - INSTALLATION OF CONNECTIONS

Drinking water tanks are manufactured using rotomoulding technology, which allows the tanks to be produced as a whole, without the need to weld individual components together, which has a beneficial effect on the mechanical strength of the tank. Polyethylene tanks are lighter than their steel or resin counterparts. Tanks made of non-toxic polyethylene are ideal for storing foodstuffs as well as technical substances used in various production processes. The polyethylene material prevents the growth of algae by being impermeable to sunlight. The tank can withstand temperatures from -20 to +80 °C.

The proposed tanks are ideal for:

-storing drinking water or other food-grade liquids both indoors and outdoors,

-the construction of buffer tanks to be used in the event of pressure drops or water shortages,

-to store water for fire-fighting purposes, laundry or dishwashing,

-supplying water in the event of a shortage of water on distribution vehicles,

-collecting and using rainwater, which can be used for irrigation or toilet flushing, etc.

Installation of spigots

The polyethylene tanks have a polypropylene lid equipped with a vent with anti-fungal protection and threaded connections. Additional inlet and outlet openings can be provided on request. Here is how to properly assemble the spigots.

1) Preparation of the hole

The hole for the spigot should be drilled with a hole saw in the centre of a flat surface located at the bottom of the tank, approximately 10 cm above the bottom of the tank. The diameter of the hole should be equal to the diameter of the spigot.

2) Installing the spigot

Place a gasket on the spigot and then, from the centre of the tank, pass it through the pre-drilled hole. If there are any problems with translation, the spigot can be lightly hammered in with a rubber mallet. Place a second gasket and nut on the spigot protruding from the tank.

3) Tighten spigot

Tighten the nut all the way, e.g. with a pipe chain spanner. Then clean the tank and the spigot of any shavings that may have occurred during assembly.
