HumidiClean™ Series HC-6000/4000 Humidifiers


The Ionic Bed. The final resting place of ordinary humidifiers.

Brace yourself. Armstrong HumidiClean
is going to change everything you know about humidifiers. Ionic beds are
made of a fibrous medium that attracts solids from the water as its
temperature rises. This minimizes the buildup of solids on inner tank
walls and heating elements. So you have a humidifier that stays clean
except, of course, for the ionic beds. And once they have absorbed their
capacity of solids, the humidifier alerts you that it’s time to change
them. It takes about 15 minutes, and it’s absolutely hassle-free.

How HumidiClean works

When power is supplied to the unit, the water fill
valve energizes, and water enters the tank. Once the level reaches the
low-water switch, the heating elements are energized (assuming there’s a
call for steam output). The unit continues to fill until the high-water
switch is energized. The humidifier then produces steam in response to
the humidistat’s input signal. The tank will fill at regular intervals
if all conditions remain constant. Periodic tank drainage is based on
active time of the heating elements, but it may be field-adjusted to
water conditions.

HumidiClean passes no current through water. Its resistance-type
design has a proven track record for safety. Totally different
compartments keep plumbing completely separated from electrical
components. In additon, Armstrong has built several other safety
features into HumidiClean. These include a key-locked access door, error
light, continual-checking diagnostic routines, high- and
low-water-level detection, internal tank temperature sensing,
over-current protection, and connections for a Class 2 alarm device.

Less scale means greater efficiency

Capacity is the first victim of the scale that quickly builds up in
traditional evaporative or steam-generating humidifiers. As scale
gathers in the pan or on heating elements or electrodes, output
declines. This gradually leads to a loss of humidity control. From this
point on, things get steadily worse. Eventually, cleaning or replacement
of the parts is a must.

HumidiClean, with its remarkable ionic bed
technology, collects deposits on its ionic bed inserts instead of tank
walls or heating elements. As a result, it operates efficiently longer,
its tank stays cleaner longer, and it maintains nearly maximum output
throughout its service life.

Saves energy, too

Most humidifiers drain every 20–45 minutes because
of carbonate buildup. HumidiClean’s ionic beds attract these carbonates
from the water, so the primary reason to drain the tank is to eliminate
sodium. Since this is typically necessary only once every 12 hours, the
unit wastes much less hot water, thereby saving energy dollars.

NOTE: This product is available with the Armstrong
Temp-R-Drain, a device that mixes hot condensate and cold water to
maintain a drain outlet temperature suitable for drainage directly to
any plumbing system. Contact Armstrong factory representatives for more
