AQUILA – The eagle has landed
Reliably smoke-free escape routes
The new 66 m high building with its special façade made of hot-dip galvanised sheet steel on the railway station square in Pratteln (CH) bears the majestic name “AQUILA”. The name is Italian and means “eagle”.
The 22-storey building with its wings, designed by the Basel-based architects Christ & Gantenbein, is deliberately reminiscent of the body of an eagle.
The AQUILA building is made up of a tower with rhomboid floor plan and three-storey wing structures attached to the side. Shops and office use space are located on the ground floor up to the third floor of the wing buildings. 76 comfortable rental apartments with 70 and 150 m² are available from the fourth to the 19th storey.
A special feature is the façade construction. It is made up of 900 timber elements and thus almost 140 m³ timber. The construction was then clad with a ventilated façade made of 3.3 mm thick, galvanised steel sheets.
PRIORIT, together with its system partner in Switzerland, JOMOS Rauchschutz AG, supplied and installed smoke control dampers for the pressure-differential type smoke control systems (RDA) for the AQUILA building. The entire pressure-differential type smoke control system was implemented by JOMOS Rauchschutz AG. Smoke control dampers normally open up in the shaft, so that they do not protrude into the escape route. Due to the shaft geometry of the rhomboid floorplan, the smoke control dampers of the type PRIODOOR ETX RDA had to open to the outside. Above the smoke control dampers a further inspection door of the type PRIODOOR ETX was inserted. All elements were framed with PRIORIT’s own PRIOWALL wall system.
In total, 16 units (smoke control dampers, PRIODOOR ETX and PRIOWALL elements) were installed.
A powder coated stainless steel surface was subsequently applied by the customer.

Smoke control damper
PRIODOOR ETX RDA
The firefighting stairs in the high-rise residential block were equipped with pressure-differential type smoke control systems (RDA) and therefore provide maximum protection for evacuation in case of fire.
PRIORIT supplied and installed 40 smoke control dampers of the type PRIODOOR ETX RDA for the air releases in the individual storeys. The large-format, single-leaf smoke control dampers were especially designed for installation in the air release shafts of pressure-differential type smoke control systems (RDA). In case of fire, the PRIODOOR ETX RDA smoke control damper is opened automatically by the RDA control. Large format cross-sections provide a free, unobstructed air release area for fire and smoke gases. The smoke control damper was given a white decorative surface, similar to RAL 9010, and therefore fits into the interior design of the stairs.
