High power condensing boiler with modular base Powercond (113 - 275 kW)
Documentation Request info

Powercond are latest-generation high-efficiency condensing thermal units equipped with a pre-mixed modulating blown-air burner with low emissions and body in aluminium and high calorific power values.
There are 5 available models, with heat input ranging from 113 to 275 kW.
They can be installed individually or in cascade, each consisting of 2 to 4 generators of the same output or different output, controlled by a cascade manger.
The Powercond thermal units must be installed in a boiler room and they must be integrated with system components and devices supplied by the manufacturer. These include specific kits, to be ordered separately, which simplify the work of the installer when installing systems with a single generator, and those of the primary circuit of cascade systems.
