TECHNICAL DESCRIPTION

The storage tank is engineered to accumulate thermal energy from various sources, including solar collectors via the lower heat exchanger. The high-performance DHW heat exchanger, partially positioned in the zone of the lower heat exchanger, enhances heat transfer from the solar system, enabling greater energy utilization directly from solar input.

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.
