XT SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Single dispersion tube
Important:
Failure to follow the recommendations in this
section can result in excessive back pressure on
the humidifi er. This will result in unacceptable
humidifi cation system performance such as
leaking gaskets, blown water seals, erratic
water level control, and spitting condensate
from dispersion tubes.
CAUTION
Connector kit location
Install the connector for increasing from
1” to 1½” (DN25 to DN40) hose or
tube immediately above the XT Series
humidifi er as shown in Figure 31-1.
Failure to install the connector kit
immediately above the humidifi er will
cause system pressure fl uctuations
and increase cylinder pressure, steam
velocity, and condensate noise.
DISPERSION TUBE WITH OR WITHOUT CONDENSATE DRAIN
• Use a hose cuff and clamps to connect the steam outlet to tubing.
• Tubing diameter must match XT steam outlet connection.
• See maximum steam carrying capacities in Table 26-1 and steam loss in
Table 27-1.
• If mounting the humidifi er above the level of dispersion tube, see "Drip tee
installation" on Page 29. See also "Vertical riser drip details" in Figure
28-1.
DISPERSION TUBE WITHOUT CONDENSATE DRAIN, XTP 002 THROUGH 006
• See Figure 31-1.
• Maximum capacity of 1½" (DN40) dispersion tube without condensate
drain is 29 lbs/hr (13.2 kg/h) insulated; 28 lbs/hr (12.7 kg/h)
uninsulated.
• Condensate can fl ow back to the cylinder against 20 lbs/hr (9.1 kg/h)
steam fl ow. Pitch the steam supply line back toward the humidifi er (see
Figure 31-1).
