The Rickard electronic wall/bulkhead VAV
diffusers are normally used in sidewalls
or bulkheads where restricted ceiling
voids exist or covered ceilings are not
available. They are very effective at
distributing air across long offices, but
when only a short distance is required,
the angle of the double deflection blades
within the housing are simply adjusted
to change the direction of the throw.
A comfortable room temperature
is maintained by varying the supply
air volume in accordance with demand.
This is achieved by opening or closing
the diffuser’s aperture which is a set of
air foil shaped aluminium vanes,
driven by a 24V AC electric actuator.
Like the linear slot electronic diffusers,
the movement of the vanes is determined
by the temperature in the space and
the set point on the wall thermostat.
Depending on the demands required,
these diffusers maintain air volumes
ranging from 100% to 10% which
effectively mix the air and maintains
a more healthy and productive
environment.
The electronic wall/bulkhead diffusers are
available in 2 heights, 100mm and 150mm.
The 100mm size is available in lengths
from 300 to 650mm and the 150mm size
comes in lengths from 500 to 800mm.
The wall/bulkhead diffuser has no
in-built temperature sensor so it must
be connected to a wall thermostat for
it to be changed to a master diffuser.
The diffuser can then operate with one
or more slave diffusers or as a standalone
system to provide the required amount
of conditioned air to the area.
