HumidiPack® Family



The Armstrong HumidiPack is a prefabricated steam humidifier system
that is ready for insertion in the duct. The HumidiPack consists of a
separator/header and multiple-tube dispersion assembly when supplied for
use with an Armstrong steam-generating humidifier. A steam-supply
control valve, strainer, steam trap and header drain traps are added
when HumidiPack is used on pressurized steam.


HumidiPackPlus combines the absorption
(non-wetting) distance-shortening performance of HumidiPack with the
additional feature of steam-jacketed “active” tubes. The result is a
dry, uniform discharge of steam for nearly any application with a steam
source from a pressurized central supply.

HumidiPack® CF

HumidiPack CF offers the performance of
HumidiPackPlus without the need of jacketing steam on pressurized steam
applications. Typically used with a vertical header configuration,
HumidiPack CF offers excellent separation of entrained moisture from
steam with preheated active tubes. The entire face area is cold during
periods of no demand, adding no energy to the air stream.

Simplified installation

The HumidiPack Family dispersion assemblies slide neatly into
ductwork or air-handling units. This frequently reduces the time and
labor required for field installations. Units with horizontal tubes and
vertical headers offer all piping on one side of the ductwork or air
handler to simplify piping.

Corrosion-resistant stainless steel

The header/separator and dispersion assembly of
the HumidiPack Family are of rugged stainless steel, providing a long,
trouble-free service life. To minimize maintenance, tube-to-header
joints are welded stainless steel rather than assembled plastic adapters
with o-rings.

Compatibility with many steam sources

HumidiPack may be used with Armstrong Series CS-10
Steam-to-Steam humidifiers and gas and electric steam-generating
humidifiers. HumidiPack is also compatible with systems that have
packaged boilers or a central steam supply to 60 psig (4 bar). The
HumidiPackPlus and HumidiPack CF may be used with packaged boilers or
central steam supply to 60 psig (4 bar).

Application flexibility

Many sizes and configurations of the HumidiPack Family are available to meet new installation or retrofit needs.

Reduced heat gain to duct air

Since no steam is admitted to the manifold
assembly unless there is a demand for steam output, there is no heat
gain to duct air when HumidiPack and HumidiPack CF are not in use.
