TECHNICAL DESCRIPTION
The DHW thermal storage tank is designed for the accumulation and storage of water preheated in an external heat exchanger for domestic hot water needs. The tank’s design includes three flanged inspection hatches, each with a cover, intended for periodic service maintenance of the tank and for installing flanged heat exchangers, enabling connection to additional heating sources. To protect the internal coating, one or more magnesium anodes are provided.
MATERIAL
The tank is made of S235JR (DIN 1.0038) carbon structural steel with an internal polycaramic coating that offers high adhesion to metal and elasticity, preventing microcracking due to thermal deformation of the tank walls. The external coating provides enhanced resistance to mechanical impacts and aggressive environments.
THERMAL INSULATION
