Sound levels refer to units with full load under nominal test conditions.
The sound pressure level refers to a distance of 1 meter from the outer surface of the unit operating in open eld.
Noise levels are determined using the tensiometric method (UNI EN ISO 9614-2)
Data referred to the following conditions:
Entering / leaving exchanger water temperature user side 12/7°C
Entering / leaving exchanger water temperature source side 30/35°C
Admissible water ow rates
Min. (Qmin) and max. (Qmax) water ow-rates admissibles for the correct unit operation.
