The DT Series ultrasonic humidifiers from Humidifirst are designed for use with air handling units and ventilation ductwork. Their unique discharge nozzles are reversible, allowing left or right sided access through existing ductwork.

Patented discharge design allows for higher ducted air velocities (300 - 2,000 fpm) and Humidifirst’s advanced microprocessor control reduces the risk of wetting in ductwork. When properly interfaced with the AHU econocycle, total system capacity can often be reduced in half, allowing, for example, a 200#/hr ultrasonic system to replace a 400#/hr steam system.

Field installation is simplified with factory supplied 10' wire harness for the humidifier and checked quick-connect water valves. Humidifirst can even provide mounting of humidifiers inside a factory built duct section.

The DT Series is made entirely of high-grade stainless steel. All Humidifirst humidifiers are 100% American made, ensuring that these humidifiers are designed for the needs of American customers. No metric nuts, bolts or tube diameters are used.
