DAILY VENTILATION SYSTEM
MANUAL OPENING
Manual opening devices are made of aluminium profiles, moved by a screw jack which is actioned by a crank handle available in different lengths.
Depending on the size of the dome, it is possible to install one (single drive) or two (tandem drive) screw jacks connected to each other and actioned by a single crank handle.
Regarding tandem opening device, pushing points are placed on the long side of the dome.
For continuous skylights, manual opening device is available on 180 cm intermediate elements.
ELECTRIC OPENING
Electric opening devices are made of aluminium profiles, moved by one or two 230 V single-phase electric motors. The end of stroke switch and motor thermal protection are included.
BOUNDED ELECTRIC OPENING SG FOR DOMES
The new patented opening device named SG bound electric opening device increases the range of electric openings, focusing attention on resistance in particular conditions.
These devices are made, for square and rectangular shapes, with aluminium profiles. The opening is always operated by a 230 V single-phase electric motor, provided with an end of stroke switch and a motor thermal protection.
Frame tightness is always guaranteed by 3 holding points, both while closing and with open skylight.
For continuous skylights, the opening device is available on 180 cm intermediate elements, with clear span greater than 125 cm.
MANHOLE OPENING DEVICE
Manhole opening device is used exclusively to allow occasional access to the roof, for example in case of maintenance.
The opening is actioned from the inside with a locking/unlocking handle provided with one or two gas springs depending on the size of the dome. These gas pistons help the operator to open the dome until reaching an 80°-90° angle.
Upon request the opening from the outside is available.
For continuous skylights, manhole opening device is available with clear span 120 cm maximum.
U1 BOUND ELECTRIC OPENING DEVICE FOR SKYLIGHTS
The new patented opening device named U1 bound electric opening device is applied to continuous skylights up to 7.20 m length, focusing attention on resistance in particular conditions.
The opening is operated by two or more 230 V single-phase electric motors, each provided with an end of stroke switch and a motor thermal protection. Frame tightness is always guaranteed by the motors and by retaining points, both while closing and with open skylight
ELECTRIC OPENING WITH RACK MOTOR
Similar to the other electrical opening devices as far as the frame is concerned, this opening device has a different functioning.
For openings up to 14 m long, the system is composed of a central motor and racks with an opening stroke length up to 100 cm upon request.
A 230 V motor allows, by means of a connecting rod, the mechanical movement of the racks
VERTICAL™
Vertical™ is a patented electric opening device with motor and racks with vertical lifting. It can be applied to both monobloc domes and continuous skylights and allows the whole opening with adjustable height.
A 230 V central motor allows, by means of a connecting rod, the mechanical movement of the racks with an opening stroke length up to 100 cm upon request.
The flashings, made of opal polycarbonate, galvanized steel or prepainted steel allow to keep the skylight open even in case of rain, at a reduced height.
NSHEV OPEN AND CLOSE SYTEMS
The Open and Close system allows opening and closing for maintenance operations only, on NSHEV devices for roofs.
NSHEVs can be activated either through emergency CO2 cylinders, or through a compressed air system with remote control.
The Open and Close system can be installed on CAODURO® devices such as SMOKE OUT® (certified for complex 300 cycles of operation), SMOKE OUT VERT™, SMOKE LAME™ PT and SMOKE LAME™ TT.
This allows the staff to check at any time the functioning of the NSHEVs over the normal scheduled maintenance provided by law, without the economic burden of an intervention on the roof and the replacement of consumables
