VTS Ventus VVS650 [24/55] Air damper

VTS Ventus VVS180 [24/55] Air damper
Design and application
» Sound attenuator consists of noise
attenuating bars installed
in the AHU casing.
» Attenuating bars of 140 mm
width lled with sound-absorbing,
inammable mineral wool (density:
60 and 80 kg/m
3
).
» Attenuating bar housing: frame made
of hot-dip galvanized steel.
» Bar outer surface: thin veil preventing
against bar lling migration to the air.
» Number of attenuating bars: 2÷13,
depending on block size.
Specication
» Max air face velocity: v=5m/s.
» Working conditions: -40 ÷ +70°C.".
SOUND ATTENUATING SECTION
Design and application
» Blades made of aluminium with rubber
gasket on the edges.
» Aluminum frame.
» Blades drive realized by means of gears
made of composite material, installed
on frame internal side.
» Damper is equipped with square pivot,
tted for actuator (dampers of cross
section greater than 4 m
2
have 2 linked
pivots).
Specication
» Air leakage at closted damper:
50 m

/h*m
2
- at 100 Pascals of
pressure difference.
» Workint temperature range:
-40 ÷ +70°C.
AIR DAMPER
Design and application
» Flexible connection made of 1
mm thick and 30 mm wide hot-dip
galvanized steel proles and polyester
fabric coated with PVC.
» Flame resistance: UL94 - HB [ISO 1210].
» Flexible connection resistant to UV
radiation.
» Working temperature range:
-30°C do +70°C.
» Max connection length
(fully spread position): 110 mm.
» Flexible connection installed on each
AHU/Duct joint eliminates transfer
of possible AHU vibrations to the
ventilation ductwork.
Specication
» Max air face velocity: 5m/s.
» Working conditions: -40 ÷ +70°C.
FLEXIBLE CONNECTION
Design and application
» Air intake louver made of aluminum
prole, blades made of ABS material.
» Air outlet louver made of aluminum
prole, blades made of ABS material.
» Protection of air handling unit installed
outdoor against meteorological
conditions (precipitation, sand).
Specication
» Max air face velocity: 5m/s.
» Working conditions: -40 ÷ +70°C.
AIR INTAKE AND DISCHARGE LOUVERS
Design and application
» Energy saving lamp with securing
shade.
» Facilitation of AHU inspection
actions: lter, fan and humidier
compartment.
Specication
» Working conditions: -40 ÷ +70°C.
INTERNAL LIGHT
Design and application
» Humidifying process based on water
adiabatic evaporation from the
humidier pad.
» Humidifying pad made of CELDEK II
material.
» Humidier housing made of stainless
steel.
» System of direct water dropping
(VVS021-VVS055).
» System of water recirculation aided
by pump (VVS075-VVS650).
» Droplet eliminator integrated with
humidier lling (VVS075-VVS650).
» System is equipped with water
drainage system preventing against
high water level in the pan and
oating valve controlling its relling
(VVS075-VVS 650).
Specication
» Max air face velocity across the
humidier pad: 3,00 m/s
(VS 21-VS 55);
4,00 m/s (VS 75-VS 650).
» Water pressure range:
0,15 ÷ 0,75 MPa.
» Requirements regarding water
quality – standard tap water.
