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.
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.
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-

FEATURES
O-type

• Compact, with highly reliable circuitry.
• Separate transducer and drive circuit sections provide superior
layout versatility.

Chamber
base
• Because the ultrasonic frequencies used are higher than with
typical household-type units, mist particle size is extremely fine.
This part is thus ideal for products intended for smaller spaces.

• A 39.2mm diameter hole is formed in the bottom of the water
chamber, which is connected using an O-type ring.
Water level is determined relative to the center of the transducer.
Screw holes are provided at four locations (refer to the technical
materials) for mounting.

The transducer can beak off if the A dimension depth is shallow.
TDK recommends a 2mm A-dimension depth and a screw tighten-
ing torque of 0.6N•m.
3.CONSTRUCTION OF NB59S
The drawing below shows an example method for transistor heat
dissipation. The attached aluminum cooling fins should fixed using
silicon rubber to a metallic water tank, etc. with sufficient head dis-
sipation capacity.
(It is recommended to use a plastic water tank. However, if a
metallic water tank is absolutely must be used, be sure to insulate
it from the power supply line.)

PRECAUTIONS
• These units are readily damaged by operation when empty
(without water). Therefore a means (float switch, etc.) should be
provided to assure operation does not occur when empty.
• Contact TDK prior to use of this unit for applications utilizing
liquids other than water.
• The unit should be used only after sufficient consideration of the
product specifications for that specific unit.
• When using units in parallel, make sure that voltage differences
do not occur between the individual transducers.
• Do not use the unit to atomize a liquid other than drinking water.
Doing so can deteriorate the transducer.
• Do not operate the transducer when the atomization unit tank is
not charged with drinking water.
• Drain water from the transducer and clean the equipment into
which the unit is incorporated if not used for a long period of
time.
• Clean the transducer periodically to prevent any degradation in
the atomizing capacity due to buildup in the transducer of such
substances as calcium, sodium, magnesium, and silicon,
commonly found in drinking water.
• TDK is not responsible for damage to the transducer resulting
from use of oscillator circuitry not supplied or not approved by
TDK.
• TDK is not responsible for worsening of unit performance
resulting from operation in environments other than those
recommended, storage in environments other than those
recommended, or use of the unit in configurations other than
those recommended by TDK for efficient mist generation.
• TDK is not responsible for the vaporization of pathogenic
bacteria or particles, not responsible if drinking water contains
substances that impede vaporization, and not responsible for
bacterial growth due to lack of a water purification function.
• Please select a plastic material of construction for the water tank
design. Metallic construction can result in electrolytic corrosion
between the chamber base and water tank.
Furthermore, if multiple units are used with the same tank, and if
each unit is equipped to be separately turned ON/OFF, the
power supply terminal for each unit should use a double-pole
switch.
• All specifications are subject to change without notice.
