The Condair Nortec MES2-025 is a 25 lb/hr (11.4 kg/h) electrode steam humidifier in the high-voltage three-phase configuration that covers the 440-600 V range. The model code reads MES2 (Generation 2 electrode series), 025 (25 lb/hr nominal output), 440-600 (supply voltage range), 3 (three phase), REM (remote-mount electronics), and CE (closed enclosed electronics). Like all MES2 units it boils potable water between submerged electrodes inside a disposable plastic cylinder, with the patented Auto-Adaptive control managing conductivity, drain, and flush automatically. The 411 cylinder is the correct disposable cylinder for this capacity at 480-600 V.

This unit is sold for parts or repair. It is missing its electrode connector pins, the contacts that link the contactor wiring to the cylinder electrodes, so the cylinder cannot be energized until replacement pins are fitted. The chassis, control electronics, and remaining hardware are otherwise intact, and electrode pin sets are an available service part. The MES2 series is used in data centers, healthcare, laboratories, pharmaceutical and electronics production, and commercial air handling.
