Steam Line
The steam line between the cylinder steam outlet and the distributor may be Nortec steam
hose, copper pipe, or stainless steel pipe or tube. The RH is an atmospheric steam generator
so it is very important no restrictions are present in the steam line and that the steam line is
sized properly to carry the full output capacity of the humidifier. See Steam Lines and
Condensate Returns on page 10 for information on selecting steam lines.
Condensate Return
Whenever steam is distributed condensate is formed in the distribution system and steam
distributor, manifold, or blower pack. Insulating steam lines is one important way to reduce the
amount of condensate formed. Steam lines are sloped so that condensate does not collect in
the lines and create a restriction to steam flow. The condensate must be collected and
removed from the system so that it does not build up and leak into the duct (or room if blower
pack is used). Condensate can be returned to the RH fill cup to reduce water waste or can be
fed to drain.
