Stulz DRH: Direct Room Humidifier

Stand-alone Ultrasonic Humidifiers
STULZ Direct Room Humidiers (DRH) are designed for stand-alone room applications. DRH are typically mounted on the perimeter wall serving mission critical applications, or any environment where tight humidity control is required.

A STULZ Ultrasonic Humidifier needs only 7% of the power required by an electric steam humidifier. Assuming a humidification requirement or 20 lbs/ hr., a DAH-16 has a power requirement of 0.495 kW at 21.1 lbs/hr. Using a comparable capacity steam type humidifier, the power requirement is 6.8 kW at 20 lbs/hr, which is an energy premium of approximately 93%.
