INTEWA indoor tank series is specially designed for above ground water storage. They are installed inside buildings or, if there is no danger of frost, outside buildings. They are used, for example, as rainwater utilization storage tanks, graywater storage tanks, clear water storage tanks, drinking water storage tanks or retention storage tanks. Due to their cuboid shape, they can be installed in an extremely space-saving manner. With a high-quality coupling system, any number of storage tanks can be linked together. The blow molding process with galvanized steel reinforcement makes them extremely stable and inexpensive. The black tank coloring prevents light penetration and thus algae formation.

Coupling is done using the INT-KS-1-NW75 coupling set for the first coupled storage tank and the INT-KS-2-NW75 coupling set for each additional storage tank. The distance between the parallel tanks is approx. 5 cm.
In the case of tank sizes INT-1100 and INT-1650, the accumulators already have the 2" coupling connections required for this purpose. For tank sizes INT-2000, INT-3000 and INT-5000, the required connections must be ordered as accessories.
