When the humidistat senses a need for additional humidity, a solenoid valve is opened and metered water flows into the patented distribution tray at the top of the humidifier. The tray assures that the evaporator pad is moistened thoroughly and uniformly for greatest evaporative efficiency.

Dry air, warmed by the furnace, is passed through the wet pad where evaporation occurs, and moist humidified air is circulated throughout the home. Unevaporated water drains from the bottom of the unit carrying off troublesome minerals. The efficiency of design ensures more water gets into the air instead of running down the drain. The 1042DM uses less water input to produce more humidity output than most competitive units.

Easy to Service

Thumb screws allow easy access to the distribution trough, the drain pan, and the evaporator pad. This makes periodic maintenance quick and easy.

No Moving Parts

No motor, fan or pump to wear out or lime up.

Manual Air Shutter

To close bypass during cooling season.

High Performance

Evaporates up to 19.2 gallons per day at industry test conditions, with a metered input rate of 3.5 U.S. gallons/hour while in operation.
