VAPORSTREAM VLC
Electric Humidifier
State-of-the-art technology in a
simple, low-maintenance humidifier.
This humidifier is designed to be
used with either softened or
unsoftened water (preferably soft-
ened). The probe-type level control
system requires water conductivity
of 100 micromhos/cm (2 grains/gal)
minimum to function, and therefore
will not operate on water treated by
reverse osmosis or deionization.

chemical-free steam and reliable,

wasted water, no wasted heat, and
very little or no downtime.
