2 . 1 Description
B
oilers of this type are composed of a cast-iron
exchanger, consisting in sections assembled by means of
nipples. Their heat transfer surfaces have been specially
designed to reach high efficiency. The exchanger is insulated
by a glass wool layer lined by lacquered steel casing panel,
itself insulated to reduce heat losses to a minimum.
These pressurized boilers must be fitted with jet-oil or blown-
gas burners, provided operating characteristics are compati-
ble with the combustion chamber size and pressure condi-
tions.
They heat premises, and, for Domestic Hot Water (D.H.W.)
production, can be coupled with a D.H.W. tank located next
to it.
