Function
Systemair circular VAV terminal units are available in two
versions:
Single skin Optima R. Single skin circular VAV terminal
units are commonly used for return air applications or for
supply applications at low system pressures.Terminal units
are ideal for single zone 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. In Optima R-I
the external acoustic insulation of fiber glass material
is designed to absorb the radiated sound power level
generated by the damper assembly. The insulation is once
again is covered by a secondary galvanized sheet steel
to protect the insulation and to add to the low frequency
sound radiated in high pressure systems.
Special design of centre averaging multipoint airflow
differential cross velocity pressure sensor assures an accu-
rate air flow readings even in difficult installations. Button
punch snap lock seams, lock form with airtight nylon
bearings to assure low casing leakage.
Available Sizes
Inlet/outlet : from Ø100 to Ø630 mm
Controls
The VAV terminal units are as standard equipped with
Belimo compact controller without any MP or other com-
munication 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 other Bus- Interfaces. Compact controllers are factory
calibrated prior to dispatch.
