UNIT DESCRIPTION
FWB-C: PERFORMANCE AND COMPACTNESS IN RECESSED CEILING INSTALLATIONS
The ducted unit FWB-C was designed for conditioning environ-
ments where it is required the installation of units in medium
head performance and reduced overall dimensions.
The range covers an air flow rate from 300 to 1200 m³/h distrib-
uted over 8 models. The heat exchanger allows the use of FWB-C
in the most different conditions.
The bearing structure in fact accommodates a heat exchanger
of 3 or 4 rows to which it is possible to combine an additional
heat exchanger of 1 or 2 rows for exceptional performance even
at low temperature differentials.
