Natural ventilation and SHEV united
The Roda AEROJET is a versatile louver blade design that serves both as a natural smoke and heat extraction system (SHEV) and as an efficient ventilation unit. It combines the advantages of smoke and heat extraction with natural air exchange and daylight illumination in buildings.
Using the thermal buoyancy generated by pressure and temperature differences inside the building, Roda AEROJET provides effective natural ventilation or reliable smoke extraction in the event of a fire. For everyday use, an integrated rain sensor system ensures reliable and windy weather-independent ventilation. In the event of a fire, the Roda AEROJET thermal relief device (TRD) is automatically switched on, either by centralized manual evacuation or triggered by the fire alarm system.
With its exceptional robustness, lightweight construction and wide range of applications, the new roda louver vane ventilation device Roda AEROJET has been specially designed to fascinate architects and builders alike.
Whether in industrial plants or office buildings, materials that emit toxic gases in case of fire are increasingly being used today.
Roda AEROJET louvre ventilation has an automatic thermal trigger mechanism that reliably opens the device in case of fire when the specified trigger temperature is reached independently of other functions. Furthermore, Roda AEROJET can be controlled via a smoke detector pulse or fire alarm panel.
During the summer months, production interruptions often occur in many industrial production halls due to extreme heat and poor air quality. The Roda AEROJET louvered ventilator provides cost-effective and noiseless ventilation that does not require additional energy expenditure. The ventilation effect becomes increasingly effective as the internal heat load increases. Roda AEROJET automatically adjusts to the natural temperature difference and requires no additional control to regulate ventilation.
Thanks to the transparent blades of the Roda AEROJET louver ventilation, natural daylight can enter the building even when the louvers are closed. This not only reduces lighting costs, but also increases employee comfort and motivation.
Roda AEROJET offers versatile options for roof installation and can also be easily integrated into various wall structures to provide the required fresh air intake. Since adequate ventilation cannot be guaranteed without fresh air, the use of supply air systems is essential. Both in regular ventilation and in fire scenarios, providing fresh air intake to the lower areas of the building is the most effective approach. During a fire, Roda AEROJET facilitates the removal of hazardous smoke gases through the incoming supply air, while supporting the formation of a low smoke layer near the floor. In addition, the supply air helps to cool materials located close to the fire source.
The Roda AEROJET louver blade unit is ideal for use in industrial, commercial and public buildings.
Roda AEROJET Louver blade Design
The Roda AEROJET consists of a fixed frame construction made of extruded aluminum profiles with EN AW-6060 (AlMgSi0.5) alloy and is equipped with a series of rotating, aerodynamically designed wings that vary depending on the size. For the wing filling you can choose between aluminum sandwich and PC 16 or 25. The opening and closing of the wings is performed by an internal pneumatic cylinder or servo motor. The pivoting points of the wings are made of aluminum and mounted on UV-resistant sliding bushings. EPDM gaskets with two sealing levels are used to minimize the outflow of hot air.
The following slat types are available for Roda AEROJET roller shutter units depending on the application area:
Via the on-site compressed air network and ventilation control box (for pneumatics) or SHEV control center (for 24V actuators):
The devices can be manufactured in a wide range of length dimensions, from 1080 mm (L) x 600 mm (W) to a fixed width of 4080 mm (L) x 2000 mm (W) with 4 to 16 slats. The width of the device consists of a frame width of 40 mm and a width of 133 mm of each slat. The length is determined by the height of each slat (250 x number of slats + 80 mm).
(Device width = number of wings x 133 mm + 40 mm)
Depending on the location and specific needs, the right model can be selected from different versions:
Roda AEROJET can be easily installed on all common roof and wall constructions thanks to its low weight and dimensions and flange designs adapted to the respective requirements.
If desired, the AEROJET ventilation and smoke extraction unit can be equipped with additional accessories that offer tangible advantages to the operator.
