Rapid-sorb®
Steam dispersion panel for
use with evaporative units
DRI-STEEM’s Rapid-sorb steam dispersion panels provide rapid,
dry steam absorption in ducts, air handling units, and spaces.
Rapid-sorb disperses steam from any DRI-STEEM steam-generating evaporative type humidifier such as CRUV®, GTS®, LTS®,
STS®, Vapormist® (Humidi-tech®), Vaporstream®, VT Series, and
XT Series.
Rapid-sorb steam dispersion panels are designed for systems
where multiple tubes are needed to handle the load and/or when
the available non-wetting distance is limited.
• Steam capacity up to 800 lbs/hr (360 kg/h)
• Better non-wetting distance compared to standard
dispersion tubes
• Models available in sizes from 10" x 10" (254 x 254 mm)
and up to 120" x 120" (3048 x 3048 mm)
• For horizontal or vertical airflow with header inside or
outside of duct
• Available with high-efficiency dispersion tubes
Rapid-sorb
High-efficiency Tube option for new and existing
Rapid-sorb
• H
ighest efficiency, short non-wetting distance
• U
p to 85% reduction in wasted energy, airstream heat gain,
and condensate production
• P
lenum approved for in-duct installation with revolutionary
PVDF insulating material
• High-efficiency tubes available for existing Rapid-sorbs.
High-efficiency tube benefits are staggering: Significant energy
savings, sizable reduction in downstream heat gain, and substantial reduction in dispersion-generated condensate. To learn more

Note:
The above data applies to all air velocities up to 1,500 fpm (7.6 m/s), and is based on air leaving the zone of humidification at conditions of 55 °F (13 °C) and
the stated % RH.

Note:
* If duct height is <15" (381 mm), tube quantities may need to increase to compensate
for reduced capacity of short tubes. Consult DRI-STEEM or see Dri-calc® for the correct
calculation.
