BOILERS AND STORAGE BOILERS

PUFFER TANKS

USE: Buffer tanks for heating systems with strong insulation, to avoid heat dispersion. One or two fixed exchangers (depending on the version) for systems with biomass generators, solar systems, integration with external sources.
CONSTRUCTION:with S235JR EN10025 quality steel sheets, assembled and welded with the use of automatic systems in controlled atmosphere. Fixed spiral heat exchangers (depending on the models) with S235JR EN10025 steel pipes welded to the tank.
art. PUFFER thermal flywheel without fixed exchangers.
art. PUFFER 1 COIL thermal flywheel with a fixed exchanger.
art. PUFFER 2 COILS thermal flywheel with two fixed exchangers.
ANTI-CORROSIVE TREATMENT: External anti-rust paint.
WARRANTY: 5 years against corrosion.
