Application
Electrode-type steam humidifiers rely on the electrical conductivity of water passing between submerged electrodes to generate steam. Over time, electrodes become coated with mineral deposits or erode, reducing efficiency and steam output. Replacing the electrode set — along with the sealing O-rings and mounting hardware — is a standard preventive maintenance procedure that keeps Armstrong EHU-Series humidifiers operating at peak capacity.
