    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.

    At a $0.08 per kWh Utility Rate:

    Ultrasonic yearly power requirement

    		3,000 hrs x 0.495 kW
    1,485 kWh
    Yearly electrical energy cost1,485 x $0.08 kWh
    $118.80
    Steam electrode yearly power requirement

    		3,000 hrs x 6.8 kW
    20,400 kWh
    Yearly electrical energy cost20,400 kWh x $0.08/kWh
    $1,632.00
    Yearly electrical energy savings$1,513.20
