Environmental requirements
Air humidity max 80% at 31 °C (87 °F)
Room temperature 5-40 °C (41-104 °F)
Heat dissipation to the room
Max 6000 W hot air during drying.
Max 1500 W during disinfection at 90 °C (194 °F)
Max external temperature of the machine 50 °C (123 °F)
Sound level
Table 1 below shows the sound power level as linear octave band values and as co-weighted, A-
weighted sound power level, both equivalent L wA and maximum LwAFmax.
Table 1
Calculated sound power level Lw for the test object, db ref 1 pW.
Octave band frequency (Hz) 125 250 500 1000 2000 4000 8000 LwA LwAFmax
Correction terms (Kok) 65 66 67 63 63 60 58 70 76
The calculated sound power level implies different sound levels LpA in different types of space.
With a larger room volume, the sound level decreases slightly and with a smaller room level it
increases slightly. Table 2 below shows three example of what to expect in practice.
