BIG B3

The main features of the BIG B3 models are their sturdiness, endurance, and outstanding heat output, along with the fact that they are easy to install and to maintain. Light, modular and corrosion-resistant, BIG B3 is the ideal radiator for plants with thermostatic valves and, thanks to their low thermal inertia, it is especially reactive in its response to commands.

PLUS

  • Double coating for lasting finish: anaphoresis + powder coating
  • Improved heat exchange = high performance, low consumption
  • 100% MADE IN ITALY
  • High technological content: 3 international patents
  • Weldless base assembled with an exclusive thermoelectric joining technology

Fondital guarantees BIG B3 for 10 years from the date of installation against all production defects providing the heating system is conforming to the regulations.
