TANK IN TANK


Thermal inertial storage-hot water production tank, composed of a unit which receives and distributes energy produced by traditional or alternative sources, directly or indirectly, via heat exchangers inside the inertial tank. The hot water required to supply the different types of thermal systems is taken from this tank: at high temperature if the water is taken from the upper part of the thermal inertial tank, at low temperature if the water is taken from the lower part. The DHW production/storage unit is installed inside the thermal inertial tank in this system.

  • High-quality S235JR EN10025 sheet steel
  • 3 Versions available: 0, 1 or 2 heat exchangers
  • Fixed spiral heat exchangers with S235JR EN10025 steel tubes welded to the tank
  • DHW production/storage unit in enamelled steel (EMAIL)
  • INSULATION in rigid polyurethane for models 220÷600 and flexible polyurethane for the remaining models
  • EXTERNAL FINISH in PVC with hinge and thermoformed cover
  • CATHODIC PROTECTION with sacrificial magnesium anodes on threaded plug
