ASSEMBLY, SET-UP AND LIMITS OF APPLICATION
Assembly and Set-up
When planning and assembling the Ultrasonic humidifiers, care has to be
taken to ensure that all materials, that get into contact with the demine-
ralized water are resistant against demineralized water. For the most
important materials, please refer to the following table.
Materials for demineralized water
Material
Temperature max.
Stainless steel (1.4571)
>100°C
PVC
(Polyvinylchloride)
60°C
PP
(Polypropylene)
>100°C
PVDF (Polyvinylidenfluoride)
>100°C
PA
(Polyamide)
60°C
PSO
(Polyethylene)
60°C
Limits in Application:
Water quality
=
< 5 µS/cm, up to 20 µS/cm
for a short time
Voltage control
=
400 V + 10% or 230 V + 10%
system
Voltage humidifier
=
48 V + 10%
Water pressure
=
0,5 bar to 6 bar in front of
humidifier
Water temperature
=
8°C bis 40°C
Air humidity
=
< 90% r.h.
Air speed
=
min. 1,5 m/sec up to max. 3,0 m/sec
When an extreme amount of dust particles is found in the air (e.g. silicone
mill in printing houses), the air must be filtered, as dust deposits on the
water would reduce the humidifier output.
