Carel UU04R1 humiSonic Parts

Ultrasonic humidifiers feature a small water storage tank and piezoelectric transducers installed at the bottom of the tank. The surface of the transducer vibrates at very high speed (1.65 million times a second), a speed that does not allow the water to move due to its inertial mass. During the negative amplitude of the transducer cycle, a sudden void is created that brings about the production of microscopic bubbles, which are pushed to the surface of the water during the positive amplitude of the cycle. This effect is called cavitation. During this process, the resulting intersecting sound waves created directly underneath the surface of the water cause very small droplets of water to separate, forming a fine mist of vapor that is immediately absorbed by the flow of air.

Preventive maintenance on the humidifier is recommended to ensure optimum system performance. Maintenance intervals depend on water quality and humidifier operating hours. The use of demineralized water minimizes maintenance intervals.
Maintenance includes:
• Checking tightness of the electrical connectors.
• Cleaning and visual inspection of the components.
• Checking water level and making sure there are no leaks.
