Frequently Asked Questions
Where can I find the most up-to-date product specifications?
Please check Coolselector 2 or the Product store for updated information.
How is the sound power spectrum calculated for this unit?
It is calculated by adding the sound power levels of the compressor and fan motor at full speed, according to EN13215 conditions.
What does the sound pressure level show at a specific distance?
The accompanying tables provide measured acoustic/sound spectra data at various distances (e.g., 1m, 3m, 10m).
Does the unit consider noise reduction when measuring sound power?
Yes, since the compressor and fan motor are in a packaged unit, the effect of noise reduction due to enclosure and insulation was considered.
