Solarbayer hygienic stratification tank HSK-SLS-500, stainless steel tube

Hygienic stratification buffer tank
HSK-SLS 500, the universal heating
centre with XXL corrugated stainless
steel pipe for a high hot water pouring
capacity for legionella-safe hot water
preparation. Two large oval tube heat
exchangers for zone loading for improved
efficiency of the solar thermal system.
Patented thermohydraulic stratification
system "SLS" in the flow and return
enables an ideal heat stratification
during charging and discharge with
immediate availability of the heat. This
enables you to achieve higher efficiency
for various heat sources and consumers.
Additional connections in the centre
area with baffle plates for more
flexibility. Numerous connections for
sensors, thermometers and an electric
immersion heater. Fire protection ISO-B1
fleece insulation made from recycled
fibres (Oeko-Tex® Standard 100) incl.
floor insulation for low heat loss.
Rugged PVC jacket with stainless
steel quick-lock system for easy
installation.
