Is there no suitable air treatment system available? Then our mechanics can install an autonomous scent duct without any problem. In that case, they will install a duct system above the (system) ceiling with discharge points in the desired rooms. A pipe is used to inject the scent mist into the scent duct. The advantage of this installation technique? That the scent mist is already dissolved in the air when leaving the air supply duct. This allows the scent to spread optimally in the room!
