TECHNICAL DESCRIPTIONS
Used to improve flexibility of pellets, stoves and burners. PUFFER 1 CTS®
are used in units with a typically discontinuous energy source such as
biomass boiler and solar thermal system.
The PUFFER 1 CTS® is characterized by multiple stratification system
based on the combination of Cordivari Labyrinth spreader for returning
heating water with a brand new stratification device that convey in the
upper part of the tank the water heated up by the lower fixed coil. This
combination ensures a perfect natural stratification inside the tank with
no valve or additional external device.
The lower fixed coil allows the possibility of connecting with a solar
system. Positioned at the bottom lower part of the buffer tank and with
very small footprint, it increases the volume available for the storage.
