Energy Analysis

Energy Analysis

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%.

In a typical application, the yearly humidification requirement is approximately 2500-3000 hrs. ROI is typically 1-2 years verses Steam or Infrared.
