Description
Series D manifolds for duct-type distribution
Where an existing duct system is available, steam is commonly
discharged into the duct through a dispersion tube. If the dispersion
tube is to be located below the humidifier, install a drip leg with
water seal.
NOTE: For all atmospheric units, please consult factory personnel for
duct applications with high static pressure (>4″ W.C.) or velocities
more than 2,000 FPM. Avoid placing dispersion tubes in downward,
high-velocity airflows. Please contact your Armstrong Representative
with questions.
NOTE: When applicable, atmospheric humidifiers should be located as
close to the air-handling system as possible and never more than 40 feet
(12 m) of equivalent pipe away.
