What the buyer is looking for
Type of service At the University Hospital Aachen (UKA), fire dampers are successively renewed, primarily because they show age-related defects and damage. These fire dampers are located in air ducts of the standard air network essentially to supply the useful areas on floor -3. Therefore, before the flap conversion, it must be ensured whether a replacement measure has to be taken for the time of the conversion. The fire dampers are in the entire 3. Basement distributed. The work is carried out both in the technical centre. If possible, the replacement of the fire dampers should be carried out on an area-by-area basis. Accordingly, the collection routes must be calculated. The selected fire dampers, including possible airtight dampers and the air duct pieces necessary for the removal, must be removed and expanded against dampers of the same dimensions with motor drive and Siemens fire alarm panel for fire dampers.
