SMOKE AND HEAT VENTILATION SYSTEMS
SMOKE OUT®
Smoke and heat natural exhaust ventilators NSHEV are designed by CAODURO® with the SMOKE OUT® mark, compliant with Regulation (EU) No 305/2011, provided with CE marking, tested, and certified according to EN 12101-2 Standard by a notified body.
They are available in a wide range of sizes and suitable for any type of roofing. Realized with quality materials, their operation is based on activation by means of compressed gas. The opening, being powerful and reliable, is ensured even in the most critical snow and wind conditions, with a 160° angle. The closing in two points, compared to that of a single point, makes the device stable and guaranteed against accidental openings.
The SMOKE OUT® can be integrated with a traditional electric opening device for air exchange needs, thus obtaining a single element able to satisfy both smoke and heat exhaust ventilation function and the lighting and ventilation requirements of rooms. The product is CE marked according to EN 12101-2 Standard at 10.000 cycles.
The SMOKE OUT® without electric motors can be supplied with Open and Close system which allows opening and closing for maintenance operations only, for a maximum of 300 cycles, by means of pneumatic tubes network and remote control.
Any kind of remote control, whether pneumatically or electrically driven, can be connected to this device.
Thanks to a tested system it is possible to combine the dual purpose, SMOKE OUT® and daily ventilation opening, on all devices ranges both for monobloc domes and continuous skylights

THE ADVANTAGES
USE OF A SINGLE ELECTRICAL ACTUATOR FOR THE OPENING AND CLOSING
There will no longer be the need to use pneumatic devices, compressed gas cylinders or additional electrical motors dedicated to ventilation. Special safety hooks guarantee the adherence of the frame to the counter frame when the device is closed.
AFTER AN EVENT THAT GENERATED THE OPENING OF THE DEVICES IN EMERGENCY, YOU SHOULD NO LONGER GET ON THE ROOF FOR MANUAL CLOSING
The reclosing is managed from the ground floor through external push button panel. This convenient and easy management offers a great advantage for all those cases where there are difficulties to reach the roof for the reclosing of the devices.
REDUCTION OF MANAGEMENT COSTS DUE TO PERIODIC CHECKS
The periodic surveillance and controls are limited to opening and closing tests from the ground floor without having to replace components such as CO2 cylinders and thermosensitive elements. Constant surveillance of the plant by the conductor of the activity represents a guarantee itself of the correct running of the devices.
ABSENCE OF AUXILIARY THRUST DEVICES
(such as gas springs) which favour the thrust when opening the devices in case of opening under load (Classification SL1000, SL500, SL250) which may lose strength over the time
Internal design
Smoke Aries® is an innovative product that was developed and produced within the company Caoduro S.p.A
Made in Italy
Like the other company products, it is produced and assembled in Italy and subsequently shipped all over the world
Single engine
The Smoke Aries® manages to move all the lights with a single motor and a 10,000 N plug
Single handling group
The handling group is also unique and Smoke Aries® adapts to different lights, from 80cm up to 200cm
Dual purpose
The SMOKE ARIES® is certified for its double function: it can open to favour natural ventilation.
Reduction of management costs
The constant surveillance of the system by the conductor of the activity guarantees the correct functioning of the devices
SMOKE SHED™
The use of NSHEVs for walls requires that natural smoke and heat exhaust ventilation system, NSHEVS, always has exposed to winds. It also requires that NSHEVS is supplemented by a wind speed and direction control system, thus avoiding the opening of devices exposed to headwinds.
Compliance with these circumstances, which are necessary to ensure correct NSHEVS operating with any weather condition, leads to double the number of NSHEVs required and to insert a control and command circuit into the system, with a significant increase in costs. The use of roof NSHEVs on saw-tooth roofs can protect the device from side wind but does not give full guarantee that in each configuration there is no headwind which contrasts smoke exit.
Upon these considerations CAODURO® has developed its SMOKE SHED™, designed and patented with suitable retractable aerodynamic spoilers, which are activated only when the device opens in case of fire.
These guarantee the Aa value (aerodynamic free area) evaluated in presence of wind. The opening angle is optimized to obtain this Aa value and does not have any protrusion, which normally the market offers with an unsightly effect.

PRODUCT DETAILS
SMOKE OUT VERT™
The application of natural smoke and heat exhaust ventilators for walls and saw-tooth roofs deserves a more in-depth analysis. The NSHEVs installed on buildings walls could be in fact exposed to overpressures due to wind effects, or could be directly hit by headwinds, thus rejecting smoke inside the building itself. Therefore, only a careful evaluation of the designer allows to predict the real NSHEVS operating conditions, by assessing the presence of causes which can negatively influence smoke and heat exhaust ventilation in the event of fire, with any external weather condition.
The SMOKE OUT VERT™ natural smoke and heat exhaust ventilators for walls, manufactured by CAODURO®, comply with Regulation (EU) No 305/2011. They are provided with CE marking, tested and certified according to EN 12101-2 Standard by a notified body with the aerodynamic free area evaluated in absence of wind conditions.
The device is made up of a natural anodized aluminium vertical frame (with or without thermal break), built with extruded profiles.
Aluminium snap-in glazing bead are suitable for holding alveolar polycarbonate sheets in opal or transparent colours or glass sheets.
The frame can be opened with a single leaf with a central cross-piece, complete with hinges, gaskets and fastening hardware.
Awning window opening device is made up of a support bracket anchored to the frame, a double effect pneumatic actuating cylinder and a decelerator with brake function to slow down the opening. Moreover, it is equipped with an actuator device with non-thermosensitive element as required by standards, unless otherwise specified.
Inspection and maintenance take place by opening the device from the outside.
There are two sealing points for fastening against possible accidental openings, which ensure frame stability in presence of extreme weather conditions.
Opening for daily ventilation by means of electric motor or compressed air is an optional.

SMOKE AND HEAT DISPOSAL OPENINGS
The Italian Decree D.M. 03/08/2015 introduced fire-fighting technical rules valid for all activities not regulated before. The Decree has brought the concept of emergency smoke and heat disposal, to facilitate flames extinguishing by rescuers. Emergency smoke and heat disposal is operated through suitable openings that generally are the same openings ordinarily available.
With this mind, we have increased our range of products for smoke and heat control with optimized openings for smoke disposal. These, connected to a smoke and fire detection system, are able to open up to let smoke escape and allow a more efficient action by rescue teams.
Openings maximum angle (up to 90°) is agreed in design stage, depending on both the size of the hole which can be square or rectangular, and the model of monobloc dome or continuous modular skylight that covers the opening.
Smoke disposal device is driven by an electric motor with variable voltage, variable stroke and electric end of stroke switch or by a pneumatic cylinder. It consists of a frame and counter frame made with shaped tubular profile with extruded aluminium rectangular section and transversal profiles. Die-cast corner brackets avoid the caulking that could cause water infiltration. Hinges and aluminium accessories are fixed to the frame by sliding plates, so as to avoid drilling and milling that could cause frame weakening and water infiltrations.
Opening and closing actions for daily ventilation can be exclusively managed by electric or pneumatic CAODURO® control boxes, which are available upon request. These can be provided with GUARDIAN™ control unit and its wind-rain sensor.
The latter is able to command the immediate closing of the connected device in case of adverse weather conditions.
Automatic closing is however inhibited if the fire emergency signal is active.
The device in open position is constrained by one or more pushing points. It is recommended not to open the device for daily ventilation in case of strong wind or adverse weather conditions unless you have installed GUARDIAN™ control unit and its wind-rain sensor.
SMOKE & FIRE CURTAINS
FIXED SMOKE CURTAINS
SMOKE HOLD™ – SHF
SMOKE HOLD™ – SHF fixed smoke curtains comply with Regulation (EU) No 305/2011. They are provided with CE marking, tested, and certified according to EN 12101-1 Standard by a notified body.
SMOKE HOLD™ – SHF curtains are certified up to: DA 180.
Curtains are made of a flexible fiberglass fabric coated with grey aluminium polymer on both sides. The upper edge of the fabric, provided with a reinforced side, is fastened to the structure by means of a metal profile, thus making the fabric adhere to the ceiling.
The lower edge of the curtains is provided with a pocket containing a steel profile that acts as a counterweight.
All fabric seams are machine-made with stainless steel wire.
ACTIVE SMOKE CURTAINS
SMOKE HOLD™ – SHA
SMOKE HOLD™ – SHA active smoke curtains comply with Regulation (EU) No 305/2011. They are provided with CE marking, tested and certified according to EN 12101-1 Standard by a notified body.
These curtains work entirely on gravity, are fail-safe and incorporate all the latest electronic innovations. They consist of a galvanized metal roller box containing a curtain made of flexible fiberglass fabric coated with grey aluminium polymer on both sides, rolled up on a winding roller with a 24V motor and with almost unlimited lengths.
The lower edge of the curtains is provided with a steel profile that acts as a counterweight to stabilize the descend and mechanically blocks the closing. This profile is finished with a white polycarbonate shaped cover.
With active smoke curtains, smoke accumulation areas can be created. The curtains fall to a certain height that must be higher than the smoke layer calculated according to ventilation systems. This height must not affect escape routes.
Smoke curtains can be placed in ceilings with open spaces in order to prevent smoke rising to the upper floors and spreading to other rooms.
Any space between ceiling and the roller box can be closed by a fabric strip just like the curtain. This one is fastened to the box, stretched and fastened to the ceiling in order to avoid any smoke infiltration.
Side retaining and sliding guides guarantee the lateral seal of smoke and heat, thus allowing a linear descend of the curtain. The guides, made of galvanized metal sheet, are necessary for curtains that operate at high temperatures (DH) and are available upon request for standard curtains (D). On the sides of the curtains, special pins are applied to the fabric to allow its sliding inside lateral guides.
ACTIVE FIRE CURTAINS
FIRE HOLD™ – FHA
Fire compartmentation is becoming increasingly important in buildings design and construction. The presence of fire curtains in buildings guarantees safe escape routes through a proper space compartmentation. Moreover, fire spread in various areas is avoided while smoke and hot gases are guided to ventilation systems.
FIRE HOLD™ – FHA active fire curtains work entirely on gravity, are fail-safe and incorporate all the latest electronic innovations.
They consist of a galvanized metal roller box containing a curtain made of flexible fiberglass fabric coated with grey aluminium polymer on both sides, rolled up on a winding roller with a 24V motor.
The lower edge of the curtains is provided with a steel T-shaped profile that acts as a counterweight in order to stabilize the descend and mechanically blocks the closing.
Fire curtains are also provided with side guides that guarantee the fire resistance between curtains fabric and compartments. These prevent fabric waving in the event of a fire due to positive or negative pressures,
which are generated inside buildings.
On the sides of the curtains, special pins are applied to the fabric to allow its sliding inside lateral guides, which are made of galvanized metal sheet.
FIRE HOLD™ – FHA active fire curtains are classified according to EN 13501-2 Standard “Fire classification of construction products and building elements”, with test report according to EN 1634-1 Standard for non-insulated fire doors.
