SOUND LEVELS
Sound dampening and silencers
Please check the maximum sound level permitted for the particular installation you are working with,
and select the sound dampening and silencers needed for the dry air outlet duct and the regeneration
air outlet duct accordingly.
Sound levels for each particular dehumidifier can be found on page 19.
Measuring sound levels
Sound levels for Cotes dehumidifiers are measured in accordance with the provisions of the
ISO11201 standard.
While the sound level is being measured, the dehumidifier is placed on the floor. Ducts for
regeneration air and for incoming air/outgoing air are installed and led out of the measuring room.
The sound level is then measured 1 metre outside the front of the cabinet (outside the large cabinet
cover), and 1.6 metres above the floor.
