DNC – Dynamic Noise Control

To reduce the noise, not the performance levels

DNC (Dynamic Noise Control) is a device for the chiller noise reduction: it enables the measurement of the noise produced by the chiller and that adapts the performance of the chiller in order to not exceed the noise constraints and to provide always a very quiet running.

Traditional sound control devices are set up to reduce the noise levels and, as a result of this, the performance, in specific time slots. The weak spot of these systems is represented by the impossibility of adjusting the performance levels on the basis of the actual noise emissions generated by the chiller: as a consequence, there may be a reduction in performance even when it is not necessary.
