Application
Ruwen is a customized air curtain installed
above your revolving door, with the exhaust
duct adapted to the diameter of the door.
The air curtain is available without heat, with
electrical heating and with water heating.
Protection class: IP20.
Operation
Air is drawn in at the top of the unit 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 door opening.

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 installed horizontally on
the roof of the revolving door with vibration
dampers on steel plates (100 x 200 mm) that
distribute the weight.
The unit could alternatively be mounted on
beams.

Electrical installation
The installation, which should be preceded by
an isolator 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 air curtain has an integrated PC board
which is connected to the selected external
control system FC. FC must be ordered
separately. FC is supplied pre-programmed.
Communication- and sensor cables are
connected to the PC board.
Should more than one air curtain be
controlled by a single FC, an additional
communication cable FCBC per unit will be

Control is supplied by 230V~ to the PC board.
The PC board is placed in the teminal box on
the side of the unit.
For units with electrical heating, the power
supply for heating (400V3~) is connected to the
terminal block accessible by opening the top
service hatch. The electrical connection is made
on the side of the unit.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
