Pro-Clean®Stratified Tank with Spherical Exchanger for Service Water and Heating
Multi-functional stratified tank system (only in combination with a spherical exchanger) made of S 235 JR steel (stainless-steel 1.4404) for service water and heating.
Backup tank with optimum stratified charging without tank mixing with inte-grated hygienic water heating using a continuous heating process with stainless-steel corrugated pipe and tapping devices. Inflow absorbers ensure optimum retention of stratification. Expandable with PSN heating tank. Area of use
■ In solar systems, water heating and backup heating ■ In biomass systems as a backup tank
■ In heat pump systems as a tank for hot water and heating Advantages
■ Optimum use of solar energy for hot water and heating ■ Simple functional concept without complicated technology (natural principle)
■ Long service life
■ Improved economic efficiency for every heating system (solar, biomass, heat pump)
■ Germ-free fresh water heating using a special corrugated stainless- steel pipe
■ Space-saving design with minimum heat loss (melamine resin insulation)
