UNIT DESCRIPTION

Comfort, low noise, and efficiency in perfect harmony!
The new series of hydronic cassette units FWH-A, with ON/OFF
motor, consists of 6 models (02-03-04-06-07-08) for 2-pipe sys-
tems and 5 models (02-03-04-06-08) for 4-pipe systems.
The engineering of the unit makes it possible to develop up to 5
kW in the cooling mode in a standard 600x600 mm modular sus-
pended ceiling and over 9 kW in the 860x860 mm modularity,
with exceptionally low noise levels in the phases for maintaining
interior comfort.
FWH-A leverages the entire DAIKIN FWEC1A/FWEC2A/FWEC3A,
FWECSA and FWEC2T/4T microprocessor controller platform
that incorporate sophisticated adjustment logics based on air
temperature, air humidity, and water temperature.
These benefits translate into greater accuracy in achieving and
maintaining the desired comfort conditions through appropri-
ate modulation of the fan speed as well as the reduction of noise
emissions, which adapt to the actual thermal load.
The suspended ceiling unit houses all the components, heat ex-
change coil, fan drive assembly, and condensate collection and
drainage system. Its structure is designed for introducing fresh
air into the space, mixing it with recovered air, and distributing
the treated air from the cassette unit to adjacent rooms.
Two tipes of intake and oulet air grilles:

FPAN grill: ABS material, available in RAL9003 guarantee opti-
mal integration into the suspended ceiling panels.
With easy access to air filter for cleaning operations.
The unit can be supplied complete with valves, including pres-
sure-independent balancing and control valves, the use of
which significantly reduces commissioning time.
FCND02A gille : design grille with Coandă effect: DIBOND ma-
terial, thanks to Coandă effect, the air is expelled parallel to the
ceiling, cooling the walls before mixing with the ambient air at
the ground. In this way the operation will be optimized during
the summer, ensuring more comfort for the occupants.
