Ultrasonic Nebulizer Humidification

Ultrasonic nebulizer is a type of cool-mist Humidifier which uses anultrasonic vibration to disperse a cool mist of water into the air. As it moves, it breaks up the water into tiny particles.

Ultrasonic humidifiers use a piezoelectric transducer to create a high frequency (1-2 MHz) mechanical oscillation in a film of water. This forms an extremely fine mist of droplets about one micron in diameter, that is quickly evaporated into the airflow.

Piezoelectric Transducer:

The main principle of a piezoelectric transducer is that a force, when applied on the quartz crystal, produces electric charges on the crystal surface.

Piezoelectric transducers are a type of electroacoustic transducer that converts the electrical charges produced by some forms of solid materials into energy. The word “piezoelectric” literally means electricity caused by pressure.

Unlike the humidifiers that boil water, these water droplets will contain any impurities that are in the reservoir, including minerals from hard water. Any pathogens growing in the stagnant tank will also be dispersed in the air. Ultrasonic humidifiers should be cleaned regularly to prevent bacterial contamination from being spread throughout the air.

Using this ultrasonic nebulizer system in a climatic chamber will have the following advantages,

  • Low maintenance
  • Low water consumption
  • Low Energy Consumption
  • No Heating systems is required to maintain humidity
  • No electrical resistance in the chamber
  • More accuracy on Humidity regulation
