Solarbayer stratification buffer tank SLS-800-S, patented SLS-System

Stratification buffer tank SLS-S 800
with patented thermohydraulic
stratification control system (SLS). The
SLS system in the flow and return line
enable ideal heat stratification during
loading and unloading with instant heat
availability. For higher efficiency with
different heat sources and consumers.
Integrated large heat exchanger for
improved efficiency of the solar thermal
systems. Numerous connections for
sensors, thermometers and an immersion
heater. Fire protection fleece
insulation ISO-B1 made from recycled
fibres (Oeko-Tex® Standard 100) incl.
floor insulation for low heat loss.
Robust PVC jacket with stainless steel
quick-lock system for easy installation.
