Installation
High-efficiency Tube option
Dispersion assemblies with the High-
efficiency Tube option are designed to
produce significantly less dispersion-
generated condensate and airstream heat
gain, which reduces wasted energy by up to
85%. These improvements are accomplished
by reducing the thermal conductivity of the
tubes with 1/8" of polyvinylidene fluoride
(PVDF) insulating material on the outside of
the tubes. These assemblies require careful
unpacking, installation, and handling. If
your dispersion assembly has the High-
efficiency Tube option, be sure to read this
section carefully.

Ultra-sorb with the High-efficiency
Tube option
DRI-STEEM humidifiers operate with several types of dispersion
assemblies for open spaces and for ducts and air handling units.
Dispersion assemblies in ducts and air handling units must be
positioned where the water vapor being discharged is carried off
with the airstream and is absorbed before it can cause condensation
or dripping.

condensation at or after the unit. This normally will be after the
heating coil or where the air temperature is highest.

– before the intake of a high efficiency filter, because the filter
can remove the visible moisture and become waterlogged;
– before coming in contact with any metal surface;
– before fire or smoke detection devices;
– before a split in the duct; otherwise, the dispersion assembly
can direct more moisture into one duct than the other.

temperature and air movement to absorb flash steam; otherwise,
condensation may form on nearby surfaces.
