Ultrasonic Nebulizer Units
Incorporate Type
NB Series
The TDK ultrasonic humidifier unit was the first such product in the
world to be developed. There is an increasing need for indoor
humidification due to the proliferation of clean air heat pumps and
central heating systems.
When the appropriate amount of humidity is added as determined
by the relationship between humidity and sensible temperature
(temperature perceived by the body), humidification is advanta-
geous from the standpoint of both health and reduced energy con-
sumption.
In addition to such home uses, these ultrasonic humidifier units
have numerous advantages for humidification of vegetable show-
cases, preservation and growth of agricultural products, industrial
applications, etc. A wide variety of standard units are available
from TDK.
