VESTA 80 dehumidifiers are utilised for summer
dehumidification of rooms with radiant panel cooling
systems.
VESTA 80 is designed and built exclusively for indoor
installation. Outdoor installation of the unit is strictly
prohibited.
The appliance is available in three versions:
• VESTA 80
FVI
- Vertical recessed exposed unit
The dehumidifier is recessed into the wall utilising a
wood frame.
• VESTA 80
HI
- Horizontal ductable unit
In this configuration the airflow at the outlet can be
routed directly into a duct and then diffused into the
room through an outlet vent.
In the VESTA 80
HI
versions the ducts,
vents (intake and outlet) and room air intake
filter must be supplied by the installer.
The structure is made of galvanized steel sheet. The
fan unit is composed of a centrifugal fan with six-speed
motor that assures high performance, efficiency, and
low noise operation.
Air treatment is provided by a refrigerant circuit
composed of pre and post-treatment coils made
of copper tube with aluminium fins, a reciprocating
compressor mounted on antivibration supports
or springs (VESTA 80V ), a capillary expansion tube
and a filter-dryer.
VESTA 80 delivers air at neutral temperature with
respect to the room air. This characteristic is assured
by the presence in the unit of a post-cooling coil through
which water from the radiant panels system can be
circulated.
VESTA 80 is controlled by the regulation and control
system, also when several units are installed in parallel.
Optimal installation for all types of system is guaranteed
by a range of optional accessories.
