TECHNICAL DESCRIPTION

The storage tank is engineered to accumulate thermal energy from various heat sources. The DHW heat exchanger is positioned in the upper part of the tank, enabling the use of the highest-temperature heat transfer fluid for rapid and efficient heating of DHW in the quantities required by the consumer.

MATERIAL

The tank is constructed from S235JR (DIN 1.0038) carbon structural steel. The external coating provides enhanced resistance to mechanical impacts and aggressive environments.

HEAT EXCHANGER

The DHW heat exchanger is manufactured from AISI 304L (DIN 1.4307) stainless steel.
