Sound Level
The 50EN/EH units are designed to work with a low acoustic level.
In any case, the following must be taken into account for the design of the installation:
- the outdoor environment for acoustic radiation,
- the type of building for the noise transmitted by air,
- the solid elements for the transmission of vibrations.
To reduce transmission through solid surfaces to the maximum, it is very advisable to install shock absorbers between the ground or structure
and the unit frame. If necessary, a study must be commissioned to an acoustic technician.
