N E B U L I Z E R S September 2015 Ultrasonic Nebulizer Units Humidifier for mist generating system Incorporate type NB Series NB-59S-09S-0 NB-80E-01-H (1/4) N E B U L I Z E R S Ultrasonic Nebulizer Units Incorporate type Overview of 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 advantageous from the standpoint of both health and reduced energy consumption. In addition to such home uses, these ultrasonic humidifier units have numerous advantages for humidification of vegetable showcases, preservation and growth of agricultural products, industrial applications, etc. A wide variety of standard units are available from TDK.

Separate transducer and drive circuit sections provide superior layout versatility. 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.

Therefore a means (float switch, etc.) should be ø18 provided to assure operation does not occur when empty. Tank base Contact TDK prior to use of this unit for applications utilizing Rubber packing liquids other than water. The unit should be used only after sufficient consideration of the Plastic case product specifications for that specific unit. (Metal case) When using units in parallel, make sure that voltage differences do not occur between the individual transducers. Screw:M4×15 Do not use the unit to atomize a liquid other than drinking water. Dimensions in mm Doing so can deteriorate the transducer. Do not operate the transducer when the atomization unit tank is The transducer can beak off if the A dimension depth is shallow. not charged with drinking water. TDK recommends a 2mm A-dimension depth and a screw Drain water from the transducer and clean the equipment into tightening torque of 0.6N • m. which the unit is incorporated if not used for a long period of time. Clean the transducer periodically to prevent any degradation in 2.CONSTRUCTION OF NB59S the atomizing capacity due to buildup in the transducer of such The drawing below shows an example method for transistor heat substances as calcium, sodium, magnesium, and silicon, dissipation.

However, if a metallic TDK. water tank is absolutely must be used, be sure to insulate it from the TDK is not responsible for worsening of unit performance power supply line.) resulting from operation in environments other than those Metal tank P.C. board Silicon rubber 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 Aluminum radiation board Transducer unit 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.
