TECHNICAL DESCRIPTION

The storage tank is designed to accumulate thermal energy from various sources, including solar collectors, via a lower heat exchanger. The internal DHW tank is located in the upper part of the tank, allowing the use of the highest-temperature heat carrier for rapid and efficient heating of DHW, as well as storing it in the required volume. The DHW reserve ensures coverage of peak hot water consumption. Thanks to its corrugated wall design, the internal tank offers sufficient resistance to external pressure fluctuations.

MATERIAL

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

INTERNAL TANK

The internal DHW tank with a corrugated (wavy) wall is made of AISI316L (DIN 1.4404) stainless steel.

HEAT EXCHANGER

The lower heat exchanger (external heating circuit) is made of C22 (DIN 1.0402) carbon steel.
