Application area
The SFS air curtain unit is supplied with
electrical heating or hot water heating.
SFS is intended for revolving doors.
SFS is mounted vertically next to the door.
Protection class: IP20.
Operation
Air is drawn in at the side of the unit and
blown out against the entrance, so that it
shields the door opening and minimizes heat
loss. To achieve the optimum curtain effect
the unit must extend the full height of the
door opening.
The grille for directing exhaust air is
adjustable and is normally angled towards the
revolving door to achieve the best protection
against incoming cold air.
The efficiency of the air curtain depends
on the air temperature, pressure differences
across the doorway and any wind pressure.
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 mounted to the left of the
door seen from inside. The unit has a curved
design which makes it an integrated part of
the door. The unit can be extended to max
3000 mm (extension without fans). Extension
hood, for heights up to 4 m, is available.
The air curtain is installed on adjustable
feet which makes it possible to compensate
for any surface undulations. The feet
are attached to the floor with fasteners
appropriate to the surface and covered by a
frame. The air curtain must always be secured
at the top.
Electrical installation
The installation, which should be preceded by
an omnipolar switch with a contact separation
of at least 3 mm, should only be wired by a
competent electrician and in accordance with
the latest edition of IEE wiring regulations.
The control system is pre-installed in the air
curtain with an integrated control card. SIRe
is supplied pre-programmed with quick-fit
connections. Modular cables are connected to
the control board. The control card is always
placed at the top of vertical units.
See manual for SIRe.
Unit with water heating
The electrical connection may be done from
above or below, according to ordering key.
Control (230V~) should be connected to a
terminal block.
Unit with electrical heating
The electrical connection may be done from
above or below, according to ordering key.
Control (230V~) and power supply for heat
(400V3~) should be connected to a terminal
block. Modular cables for SIRe control board
should be drawn inside the unit when the
connection is made from the bottom. Bundle
the cables inside the unit to prevent that they
will be drawn into the fans or get in contact
with the heating elements.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In
the distribution board it is to be indicated
that ”the air curtains can be supplied from
more than one connection”.
See wiring diagrams.
Ensure that the service hatch is accessible
and can be fully opened.
