Overview

Humidifiers using tap or softened water
control water levels electronically using a
three-rod probe. The controller responds
with the above actions when the water level
reaches each rod.

Fill valve opens when water
level is below this probe.
Low-water cutoff. Power to
heaters is cut if water level
drops below this probe.
Fill valve closes when water
level rises to this probe.
Humidifiers using DI/RO water control water
levels using a float valve and low-water
cutoff switch.
Tap/softened water
Humidi-tech humidifiers with tap/softened water (shown above)
use electricity to heat tap or softened fill water into steam for
humidification. A conductivity probe monitors the water level;
therefore, water conductivity must be at least 30 μS/cm for proper
operation. Humidi-tech with tap/softened water will not operate
with DI/RO water. For DI/RO water, use Humidi-tech with the
DI/RO water option.
DI/RO water option
Humidi-tech humidifiers with DI/RO water systems (systems using
deionized water or water that has been treated using reverse osmosis)
use electricity to heat DI/RO fill water into steam for humidification.
Water level is controlled with a float valve and low water cutoff
switch. Float valves are compatible with DI/RO water only.
Humidifiers with the DI/RO water option are virtually maintenance
free and require little or no downtime.
Water type conversion
Humidi-tech tap/softened water humidifiers can be converted in
the field for use with DI/RO water, and Humidi-tech DI/RO water
humidifiers can be converted in the field for use with tap/softened
water. Contact your DRI-STEEM representative or distributor for
parts and instructions.
