(1/3) 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 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.

Therefore a means (float switch, etc.) should be o24 provided to assure operation does not occur when empty. o18 * Contact TDK prior to use of this unit for applications utilizing Tank base liquids other than water. Rubber packing * The unit should be used only after sufficient consideration of the product specifications for that specific unit. Plastic case * When using units in parallel, make sure that voltage differences (Metal case) do not occur between the individual transducers. * Do not use the unit to atomize a liquid other than drinking water. Screw:M4x15 Doing so can deteriorate the transducer. Dimensions in mm * 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 tighten* Drain water from the transducer and clean the equipment into ing torque of 0.6N * m. which the unit is incorporated if not used for a long period of time. 2.CONSTRUCTION OF NB59S * Clean the transducer periodically to prevent any degradation in The drawing below shows an example method for transistor heat the atomizing capacity due to buildup in the transducer of such dissipation.

However, if a from use of oscillator circuitry not supplied or not approved by metallic water tank is absolutely must be used, be sure to insulate TDK. it from the power supply line.) * TDK is not responsible for worsening of unit performance 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 Aluminum radiation board Transducer unit 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. 002-03 / 20120316 / ef441_nb.fm
