Function
Single skin round to square VAV terminal units is common-
ly used for supply air applications or for return air applica-
tions at low to medium system pressures. Optima-RS VAV
terminal units are ideal for multizone control with supply
and return in master and slave setup such as offices, hotel
rooms or meeting rooms where the required cooling and
heating load will vary on demand.
Design
VAV unit housing constructed of galvanized steel sheet,
large surface pleated for extra stiffness. Internal thermal
acoustic insulation of fibre glass material, dual density
insulation cover tissue is used to protect the fiberglass
insulation to protect the deterioration of the insulation for
air speeds of 20-25m/s.
Acoustic insulation in the housing has aerodynamic flow
for extra low sound level. Double skin low leakage ellipti-
cal damper with airtight neoprene gasket seal. Special
design of centre averaging multi-point airflow differential
cross velocity pressure sensor assures an accurate air
flow readings even in difficult installations. Button punch
snap lock seams, lock form with airtight nylon bearings
to assure low casing leakage. Rectangular outlet with M8
riveted nuts, suited for connecting to duct flange. 12 mm
aluminium shaft with nylon bearings
Available Sizes
Inlet/outlet : from Ø125 to Ø400 mm
Controls:
The VAV terminal units are as standard equipped with Be-
limo compact controller without any MP or other commu-
nication capability to be used as stand alone or in Master
and Slave setting. The compact controllers which are
supplied with MP-Bus communication capability, can be
connected later in time to building managment systems to
create a zone controle by creating bus-rings solutions
The compact controllers are equally available with
MP-Bus, LON and ModBus communication capability on
demand. The compact controllers which are supplied only
with MP-Bus communication can be connected later in
time with or per-zones with other Bus-Interfaces. Compact
controllers are factory calibrated prior to dispatch.
