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.
|At a $0.08 per kWh Utility Rate:|
|Ultrasonic yearly power requirement||3,000 hrs x 0.495 kW|
|Yearly electrical energy cost||1,485 x $0.08 kWh|
|Steam electrode yearly power requirement||3,000 hrs x 6.8 kW|
|Yearly electrical energy cost||20,400 kWh x $0.08/kWh|
|Yearly electrical energy savings||$1,513.20|
|lbs/hr||5.3 - 39.6|
|kg/hr||2.4 - 18.0|
