Ultrasonic Humidifiers
Course Highlights

This online engineering PDH course describes ultrasonic humidifier applications, energy saving potential, maintenance considerations, supporting technology, life cycle costs and case studies of ultrasonic humidification systems.


Humidifiers are used in buildings to maintain humidity levels to ensure quality and handling capabilities in manufacturing processes, to lower the transmission rate of disease-causing bacteria in hospitals, to reduce static electricity in manufacturing clean rooms and in computer rooms, and to provide higher levels of employee comfort.  Ultrasonic humidifiers are proven to reduce humidifier energy use by 90 to 93%.


This 2 PDH online course is applicable to engineers who are involved with HVAC system design and retrofits where humidification is used to comply with codes and standards and/or for providing conditions required in the space for a variety of reasons including materials in the space and comfort considerations.

Learning Objectives
