Ultrasonic Humidifiers

Rapid Cool offers Rapid-Mist range of Ultrasonic Humidifiers that work on the principle of ultrasonic vibrations. Thus no heating elements are required for humidification. A conventional humidifier with heating elements would requires 750 W of electricity to humidify 1 ltr of water; whereas Rapid-Mist humidifier requires only 100 W to humidify 1 ltr of water. Hence there is up to 85% of saving in electricity. Ultrasonic humidifiers use piezo-electric transducer to create a high frequency mechanical oscillation in water. The water tries to follow the high frequency oscillation but cannot because of its comparative weight and mass inertia. Thus, a momentary vacuum is created on the negative oscillation, causing the water to cavitate into vapour. The transducer follows this with a positive oscillation that creates high pressure compression waves on the water's surface, releasing tiny vapour molecules of water into the air. This is an extremely fine mist, about one micron in diameter that is quickly absorbed into the airflow. In almost any commercially useable space, where air is being exchanged, humidifying that air is almost always desirable and often essential. Compared to steam canisters and infrared humidifiers, ultrasonic humidifiers require about 90% less electricity to humidify the same size space. In addition, this small electricity requirement can lead to significant savings in the cost of wiring, electrical distribution boards, standby generation and even the main input transformer to the building. Energy analysis calculations show that the lower energy costs, alone, can give the customer a payback in one to two years. Rapid-Mist humidifiers are almost maintenance free, as the water is filtered before humidification, there are no dust particles, mud or scaling inside the humidifier. The only maintenance required is cleaning or replacing the filter periodically. Simply put, the ultrasonic humidifier system does not generate heat at any point in the humidification process.
