Application area
3200-R Series is a compact air curtain for recessed
mounting. The air curtain is available without heat,
with electrical heating and with water heating.
Recommended installation height up to 11ft.
The air curtain has an integrated control system
and can also be remote controlled.
Protection class for units with electrical heating:
IP20.
Protection class for units without heating and units
with water heating: IP21.

Operation

Air is drawn in from underneath and blown
downwards shielding the door opening and
minimizing heat loss. To achieve the optimum
curtain effect the unit must extend the full width of
the opening.
The grille for directing the outlet air is adjustable
and is normally angled outwards to achieve the
best protection against incoming air.
The efficiency of the air curtain depends on the
air temperature, the pressure differencial across
the doorway and any wind load.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.

Mounting
The air curtain is installed horizontally with the
outlet air grille facing downwards as close to the
door as possible, concealed in the false ceiling.
The only visible part of the unit is the underside
which is level with the ceiling. The service hatch
must be accessible, nothing should prevent it
being fully opened.
The unit is ready for suspension with threaded bars
on its outside. The threaded bars can also be fixed
on the inside of the unit e.g. when mounted on a
solid suspended ceiling.
For the protection of wider doorways, several
units can be mounted in series alongside each
other. Minimum distance from outlet to floor for
electrically heated units is 70.9 in.
