How The heaterSteam Works

Electric immersion resistance heaters are contained inside a stainless steel canister. When humidity is needed,

the elements heat the water into steam. The heaterSteam is unique in that the heating elements are encased

in Aluminum to permit them to operate dry without burning up. Special electronics even detect when

maintenance is needed.

Operation:

On a call for humidity, the HeaterSteam humidifier first checks the incoming water conductivity, water level and

then runs diagnostics. The heating elements are then energized, and if modulating, the SSRs are pulsed to

control the steam output to match demand. Periodically, the humidifier will drain away part of the cylinder water

and replace it with fresh water to dilute the minerals in the cylinder and extend the maintenance cycle. Full

diagnostics monitor the incoming water conductivity, foaming action in the steam cylinder, heater operation and

output, and water level.

Features:

• Automatic level control and draining by conductivity

• Overheat protection of heaters to prevent burn-out and predict maintenance

• Backflow prevention

• Anti-Foaming System
