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

Stratification buffer tank SLS 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. 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.
