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.
