AIR CURTAINS
Air curtains are produced in accordance with the latest technical standards. Our quality assurance program
includes material controls and function tests in every steep of the process to obtain a high quality and reliable
final product with a long trouble-free life.
Air curtains are ideal for controlling the interior ambient of industrial and commercial premises that need to
maintain the doors open. Air curtains create a laminar air stream over the opening doorway and acts as an
invisible barrier which efficiently divides the interior ambient from the exterior; reduce heating and cooling
cost meanwhile increasing the employees and clients comfort. They contribute to a comfortable climate in the
entrances and interior of the premises, protect from the cold and the heat, repel gust of wind and minimize
the entrance of airborne dust, fumes, pollutants and flies.
The casing is made of zinc plated sheet steel finished in epoxi-polyester white, RAL 9016, as standard.
Microdrilled suction grill with washable dust filter functions. Aluminum blow-out nozzle, airfoil-like profiled. .
Optima models are equipped with direct drive external rotor motor of extremely low noise level, 100% speed
controllable, protected through thermal contact and directly connected to the tangential impeller.
High efficiency impeller statically and dynamically balanced according to DIN/ISO 1940, quality 2,5.
Water coils are available for pumped warm water 80/60ºC. The tested pressure is of 8 bars.
Electric heating coils are protected against overheat through thermal contacts and sensors and when the air
curtain is switched off, the fans continue working until the unit has cooled sufficiently. Electrical power supply
box and “plug and play” control connector plate are placed on top of the unit and makes unnecessary to open
the service door.
The communication between the air and heating control panel is digital through low-voltage cable with
telephone plugs (RJ45). Prepared for all kinds of accessories (thermostatic valves, room thermostats, door
contact, automatic controllers, anti-frost protectors, etc…).
WORKING CONDITIONS
Air curtains are designed for use with ambient air, pumped warm water or electric heat.
The standard heated versions are equipped with an electric heater or water coils of 80/60ºC or 60/40ºC
In order to avoid overheating in the motors and internal elements, the water circulation valve must be closed
while the air curtain is turned off. The ambient temperature should always be over +4ºC. For lower
temperatures the unit must be protected with anti-freeze thermostat.
The suction temperature shouldn’t be over 40ºC. The discharge air temperature shouldn’t be over 50ºC.
TRANSPORT AND STORAGE
Attention! Heavy load.
Do not steep under hanging load during the transport or assembly.
When carrying material, make sure it is not damaged by the forklift (fork penetration in the packaging).
Please observe the packaging instructions.
Store in dry place and weather protected in its original packing. Cover opened boxes with a tarpaulin and
protect the unit against the influence of dirt.
Don’t put heavy loads or steep on over the packed unit and avoid distortion of casing or other damages.
Storage temperatures are between -20ºC and +40ºC.

MOUNTING INSTRUCTIONS
Installation work, electrical wiring, mechanical maintenance and service must be done by
qualified persons observing these instructions and in accordance with all applicable
norms and standards.
Each unit should be able to be disconnected according to the applied norms. If the unit
is operated with additional controller, please consider the instructions of operation
manual of controller.
For all electrical connections there is no need to open the service door. All necessary
connections are external and placed on the top of the unit.
Power supply
The connection of the power supply is made on the top-external part of the air curtain.
For an ambient air or water heated air curtain, only single phase 230V is needed. In case of an electric air
curtain you must connect both single (230V) and three-phase (380V) in white connection box.
Junction box for air only and water heated air
curtains: Terminals L, N, (230V) and Earth.
Junction box: terminals 2, 3, 4 (three-phase) for
electrical heating and L, N, (230V) and Earth for
fans.
Control connector plate
To connect the controller there is a plate located on the top of the unit. The communication between the
connector plate and the controller is digital through low-voltage cable with telephone plugs (RJ45). This
cable, 20m length, is included with the air curtain.
There are two types of connections: for water air curtains or only air with the telephone plugs and the green
terminal plate for the electric valve (photo on left) and for electric air curtains with telephone plugs and the
black connection box (photo on the right).
Ceiling or wall mounting
Units are provided with 4 suspension points (M8) located on the top of the unit and also 4 threaded ones at
the back of the unit (M8). This way there can be used ones or others depending on the installation (inceilining mounting or wall-mounting). The exact situation of the fixation points is reflected in the curtain
dimensions paragraph.
A minimum of 150mm is recommended above de top of the unit to allow for wiring to power supply junction
box, connectors plate and service. The curtains should be assembled in the ceiling using threaded rods,
tensors, wall mounting brackets and other supports.
The anchor should be managed according to each unit weight shown on the technical data page.
Fixation angles can be supplied as described in the accessories paragraph.
Warm water heat exchangers
Two thread connectors of ½” inches are external and placed on the top of the unit.
It is recommended to install 2 shut-off water valves (supply and return) in order to close the circuit and avoid
water leakage during coil maintenance or repair.
In addition, it’s also recommended to install a draining point in the highest part of the heating water circuit.
When required, install a secondary pump in order to increase the efficiency of the thermal exchange.
Electrical heat exchanger
The electrical heat exchanger is already connected.
The part of maneuver works with 230V and the power with 400V three phase current. The heat exchanger
has 3 resistances in bar form that combined among them they give us 2 stages of power. The first stage
provide us 2/3 of the total power and the second one the maximum power.
All electrical heat exchangers are protected against overheats. They have a security that rearms automatic
when the temperature it’s over 50ºC and another with manual rearms for temperatures over 80ºC that blocks
only the electrical heat exchanger. Also, in case we turn off the air curtain and the temperature exceeds of
50ºC, the air curtain will start the fans until the temperature descends of this degrees.
The electric controllers have the option of external thermostat that turns on and off the heater in order to
control the temperature.
During the first uses it usually removes scent but it disappears in a few days.
