TECHNICAL DESCRIPTION

The storage tank is designed for accumulating thermal energy from various sources, including solar collectors via the lower heat exchanger. The DHW heat exchanger is located in the upper part of the tank, allowing the highest-temperature heat carrier to be used for quick and efficient DHW heating in the required volume.

MATERIAL

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

HEAT EXCHANGERS

Lower heat exchanger (external heating circuit): Made of carbon steel C22 (DIN 1.0402). DHW heat exchanger: Made of stainless steel AISI 304L (DIN 1.4307).

THERMAL INSULATION
