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.

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 (in-

ceilining 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.

WORKING INSTRUCTIONS

For security, the air curtains must always be stopped through the controller. Never stop

the air curtain disconnecting the main electricity supply.

We enclose wiring diagrams of air curtains with the corresponding controllers.

Connector plate characteristics:

(placed on top of the unit)

Relays and transformer: It adjusts the fan speed through voltage variation by transformer so we have a

high and medium speed.

Controller’s common characteristics:

• Two speed air discharge.

• Memory: Guarantees that in the event of a power shortage, the selected speed will be maintained

when the service is re-established.

• Telephone cable and digital communication: “Plug and play” easy connection through telephone

cable and digital communication between the controller and the air curtain. Digital communication is

more reliable than analog, even at long distances.

• External ON/OFF: Inside the controller there is potential free contact (normally open) for remote

ON/OFF by any other external device. The most common uses are, for example, the connection with

programmable clock timer, room thermostats, door contact, DDC, fire alarms, etc…

Water heating controller

Electrical controller’s common characteristics:

Two speed systems that adjust air volume and two different heat powers (C1, C2).

• Thermal Limitation: Due to its special design, the only thermal limitation of this equipment is that, to

work the heating, there must be any speed selected, what allow us to choose the maximum heating

capacity with the minimum ventilation.

• Thermostat of delay: When the equipment is stopped, and it has been working, the electrical

heater is still heating during several minutes by thermal inertia with the consequent increase of

temperature. In order to avoid internal damages by overheating, there is a delay thermostat settled at

50ºC having the function to keep running or turn on again the fans automatically until the temperature

inside the equipment goes under 50ºC.When done, the fans stop automatically. The emergency

speed is indicated by a flashing green LED

• Safety thermostat: Thanks to this security system the heating won’t stop for an external temporally

reason and only will turn on against a real failure. For example, a delay in cleaning the inlet grill o a

high external temperature would be an external temporally reason. Instead, the motor damage could

be a failure capable of blocking the heating system.

If the internal temperature increases up to 50ºC the air curtain reacts increasing steep by steep the

fan speed until the temperatures goes under 50ºC. If the air curtain reaches the maximum speed and

the temperature inside is still over 50ºC, the air curtain automatically reduce the heating power steep

by steep until OFF position if necessary.

The air curtain returns automatically to the programmed fan speed and heat step if the temporally

failure cause disappears and the internal temperature decreases to 40ºC.

The programmed speed and heat are indicated by lighted green LED’s. The emergency speed is

indicated by a flashing green LED. The emergency heat disconnection in indicated by a red LED

“OFF”. The heat blockage is indicated by the same red LED “OFF” flashing at higher speed. In this

situation manual reset is needed.

Auxiliary functions controller:

In case of thermostat installation, the bridge must be removed from the inside of the controller between

Terminal 4 and 5.

Optional room thermostat: The curtain is equipped with the necessary contacts (4 and 5 terminal

block) to install a room thermostat for ON/OFF control of the heating elements that turns off when

reaching the temperature programmed. Installation of room thermostat is recommended when the air

curtain is installed in a small dimensions area or when the air curtain is used also as a heating element of

the premise. In case of the thermostat installation, the bridge inside the terminal 4 and 5 must be

removed.

MAINTENANCE INSTRUCTIONS

Air curtains don’t need any kind of maintenance except the cleaning the casing (inside and outside)

and the inlet grill.

The inlet grill has also filter functions to prevent dust settling in the internal elements. For an optimal

function is essential to clean the inlet grill regularly, we recommend every two weeks (depending on amount

of the incoming air dust). The cleaning can be easily done with a vacuum cleaner with a soft brush in order to

avoid damages in the micro drilled grill.

The casing of the air curtain can be cleaned with a wet cloth and non aggressive detergent. Don’t use

caustic soap, dissolvent or acids.(surface protection will be destroyed)

Don’t use water or steam for cleaning the internal parts and components of the air

curtain.

It is forbidden to open the service door in operation (risk of electrical

discharge and being trapped in fans).

Service and maintenance should be done only by skilled and

introduced workers.
