PUFFER 1 CTS S APPLICATION Storage of hea ng hot water. MATERIAL Mild steel construc on with exterior paint. No an -corrosion treatment required due to the buffer s closed circuit system. HEAT EXCHANGER 1 mild steel fixed heat exchanger. TECHNICAL DESCRIPTION Used to improve flexibility of pellets, stoves and burners. PUFFER 1 CTS are used in units with a typically discon nuous energy source such as biomass boiler and solar thermal systems. PUFFER 1 CTS is characterized by mul ple stra fica on system based on the combina on of Cordivari Labyrinth spreader for returning hea ng water with a new stra fica on device that conveys in the upper part of the tank the water heated up by the lower fixed coil. This combina on ensures a perfect natural stra fica on inside the tank with no valve or addi onal external device. The lower fixed coil allows the possibility of connec ng with a solar system. Posi oned at the bo om lower part of the buffer tank and with very small footprint, it increases the volume available for the storage. INSULATION High thermal insula on with ecological hard polyurethane foam.
