How to Treat Humidifiers
Humidi-Treat and the NP Series are two solutions that Nu-Calgon offers
to resolve common scale difficulties that develop in humidifiers.
Select the appropriate product for your humidifier based on system capacity:
• Use Humidi-Treat in humidifiers with a daily water capacity less than or equal to 25 gallons.
• Use the NP Series in humidifiers with a daily water capacity greater than 25 gallons.
Please see reverse side for product information.
Advantages of Treating Humidifiers with
Humidi-Treat or the NP Series:
• Reduces scale accumulation
• Less frequent humidifier cleaning
• Helps maintain design capacity
• One cartridge lasts a full season
• Very economical
Application:
Evaporative power humidifiers using recirculated water or
rotating evaporative surfaces are often troubled with loss of
capacity and efficiency due to sticking solenoid valves and
the buildup of lime scale deposits on evaporative surfaces.
If unchecked, these problems can eventually cause the
humidifier to stop operating.
Humidifier manufacturers recommend periodic inspection
and, when necessary, removal of scale deposits through
cleaning. However, the frequent cleaning necessary to
maintain rated capacity can be very time consuming and
costly. This inconvenience is often amplified in areas where
the supply water has a particularly high content of dissolved
solids. Alternatively, you can save time and resolve issues
created by scale accumulation by implementing a preventative
maintenance program by means of filtration with Nu-Calgon's
Humidi-Treat or NP Series. Proper treatment, in combination
with a bleed-off (a "draining-away" or periodic dump of
reservoir water), reduces scale buildup and removes sediment
to the point where they no longer constitute a major problem.
Treating Smaller Humidifiers with Humidi-Treat:
For humidifier systems using up to 25 gallons of water
per day, scale inhibition can be accomplished by installing
Humidi-Treat on the water line that supplies water directly
to the humidifier. Before each heating season, clean the
pad or install a new pad before installing Humidi-Treat.
