NTO spiral ducts are suitable for smoke control
The NTO spiral duct replaces the NTO-T spiral duct. From now on, all ETS NORD round ventilation ducts will be CE certified smoke control ducts.
“It’s easier for our customers if there are no longer two separate ventilation ducts, only one of which is suitable for smoke control,” Product Group Manager Oskari Mattila explains.
The CE marking and rating can be found on the side of the duct. The NORDsmoke parts can be ordered separately and you can identify them from the -T letter ending.
