Notes:
• Use DRI-STEEM's hard pipe adapter kit to
connect the steam outlet to hard pipe. Use a hose
clamp to connect the steam outlet to vapor hose.
Use a hose cuff and clamps to connect the steam
outlet to tubing.
• Thin-walled tubing heats up faster than heavy-
walled pipe causing less steam loss at start-up.
• Hard pipe or tubing diameter must match
HUMIDI-TECH steam outlet size (DN40 or DN50).
• See the Maximum Steam Carrying Capacity and
Steam Loss tables on Page 18.
• Maximum capacity of dispersion tube (without
condensate drain):
– DN40: 13 kg/h
– DN50: 25.8 kg/h
• Orient dispersion tube so that tubelets (steam
orifices) point up.
• When mounting the humidifier above the level
of dispersion tube, see the drawing on Page 17.
• Failure to follow the recommendations on this
page may result in excessive back pressures on
the humidifier. This may lead to dispersion tube(s)
spitting, steam blowing through water seals, or
leaking gaskets.
• The table at right shows hose kit sizes by humidi-
fier model. A hose kit includes vapor hose, a
dispersion tube and hardware. Note that the
capacities of models VM-30 and VM-34 require
multiple tube assemblies and therefore cannot use
a hose kit. For multiple tube assemblies, see
information on RAPID-SORB on Page 16.
