Solarbyer hygienic stratification tank HSK-SLS-1500-Plus, stainless steel tube

Hygienic stratified storage tank
HSK-SLS 1500 PLUS, 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 generators and
consumers. Additional connections in the
centre area with baffle plates for more
flexibility. Numerous connections for
sensors, thermometers and an electric
immersion heater. Double fire protection
fleece insulation ISO-B1-PLUS with 220mm
thickness 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. In order
to penetrate the second insulation
layer, we recommend the optionally
available connection piece extensions as
well as the B1-Plus thermometer set.
