Usage
Function
For ventilation of larger rooms in industry, shopping malls,
hangars, arenas and similar buildings, there will typically be a need for both heating and cooling. This makes
demands on being able to vary the jet pattern from horizontal (cooling needs) to vertical (heating needs). This is in
order to avoid too great a velocity in the occupied zone in
the cooling situation, and that the air penetrates the occupied zone in the heating situation, so the greatest amount
of efficiency is obtained.
The diffusers have an adjustable jet pattern, which makes
the diffusers suitable for both heating and cooling. The jet
pattern can be adjusted manually or with several types of
electric motors.
RCW/RCWB is available with a thermal actuator, where
the jet pattern is adjustable in relation to the supply air
temperature. This way costly electrical work for the individual diffusers is saved.

Description
RCW is a rotation diffuser particularly suitable for rooms
with a high ceiling.
7
The diffuser is equipped with adjustable blades, so the supply air pattern can be changed from vertical to horizontal.
8
The blade settings can be adjusted manually, or the function
can be automated using various types of motor. RCW with
manual blade adjustment is supplied as standard with a
blade setting of 30°.
The motorized models are supplied as standard with a blade
setting from 30° to 75°. In the motorized versions, RCW can
be supplied with an electric on/off motor, a modulating
motor or a thermal actuator, where the supply air pattern is
changed in step with the supply air temperature

Description
RCWB is a rotation diffuser (RCW) with integral box, particularly suitable for rooms with a high ceiling.
The diffuser is equipped with adjustable blades, so the supply air pattern can be changed from vertical to horizontal.
The blade settings can be adjusted manually, or the function
can be automated using various types of motor.

RCWB with manual blade adjustment is supplied as standard with a blade setting of 30°.
* Motorized models weigh approx. 1 kg more than the
weight stated in the table above.
The motorized models are supplied as standard with a blade
setting from 30° to 75°. In the motorized versions, RCWB
can be supplied with an electric on/off motor, a modulating
motor or a thermal actuator, where the supply air pattern is
changed in step with the supply air temperature.

HLD is a circular high level displacement diffuser adapted
for industrial requirements. HLD is equipped with a damper
function, which makes it possible to vary the supply air pattern between horizontal or vertical, depending on whether
heating or cooling is required. The switch can be made manually, or it can be automated using several types of motor.
The external dimensions of the diffuser are adapted to the
connection, making it easy to integrate into an ordinary duct
system. HLD can be suspended from or installed on a wall
or column using the installation bracket, which ensures
great flexibility no matter how premises are used.

Capacity
Supply air
Volume flow qv [l/s] and [m3/h], total pressure Δpt [Pa], throw
l0.2 [m] and sound power level LWA [dB(A)] can be seen in the
diagrams.
With its special design, HLD is suitable for the supply of
large volumes of air with short throws in a limited area. This
concentrates the supplied air in a small area within a larger
space, after which the air distributes itself around the
premises. Normally, a horizontal dispersal pattern is recommended in cooling situations and a vertical dispersal pattern
in heating situations.
Throw l0.2 / turning point l0.0
Throw l0.2[m] can be seen in the diagrams for isothermal air
at a speed of 0.2 m/s. Turning point l0.0 [m] can be seen in
the diagrams for heated air, +5 K +10 K respectively.
Frequency-related sound effect level

The sound effect level in the frequency band is defined as
LWA+Kok. Kok values are specified in charts beneath the diagrams on the following pages.

Planning
HLD with cooled air works in much the same way as displacement ventilation. Displacement ventilation has a higher
temperature efficiency than mixing ventilation, and thus
more power is discharged with the same volume of air and
the same cooling temperature. For the calculation of discharged power in a cooling situation, use the calculation
method for displacement ventilation. For HLD with heated
air, power is calculated as for mixing ventilation.

The near zone is shown for two different heights, one “inner”
near zone a0.2 (1.8 m) defined as the distance from the diffuser where the speed at a height of 1.8 m is 0.2 m/s, and an

Description
The diffuser can be switched between horizontal and vertical supply air and is therefore ideal for the supply of both
heated and cooled air.
Installing an FKD diffuser up to size 400 in a plenum box
type MBB can help to achieve a stable airflow to the diffuser
as well as realise the potential for individual adjustment.
• Suitable for both supply and exhaust air
• Vertical or horizontal supply air pattern
Maintenance
The multi-cone insert can be removed to enable cleaning of
internal parts or to gain access to the duct or box. The visible parts of the diffuser can be wiped with a damp cloth.
