GENERAL

GENERAL FEATURES

This steel boiler range features 3 gas passes with no flame inversion.
This design minimises the formation of nitrous oxides (Nox) due to the high temperatures and long flame stay times typical 
of traditional boiler furnaces.
The boilers in this range have been designed for low temperature operations (return at 38°C) without condensate pro-
duction. For this reason, a double tube and the differential distribution of water temperature inside the body is essential. 
In addition, a special smokebox refractory protection maintains the high temperature of parts in contact with combustion 
products.
The boilers are classified as “high performance” boilers according to the regulations in force due to their extremely high 
efficiency deriving from optimisation of heat exchange and complete insulation of the exposed surfaces.
