Connecting to humidifier with tubing or pipe
• See Figures 30-1 and 31-1 for interconnecting tubing and pipe
pitch requirements for single tube applications. See Table 33-1
for interconnecting tubing and pipe pitch requirements for
Rapid-sorb applications.
• Support interconnecting piping between the humidifier steam
outlet and the dispersion system with pipe hangers. Failure
to properly support the entire steam piping weight may cause
damage to the humidifier tank and void the warranty.
• Steam supply adapters are available from DRI-STEEM. These
adapters convert a tubing outlet on the humidifier to threaded
pipe, allowing a pipe connection.
• 90° elbows are not recommended; use two 45° elbows, 1' (0.3 m)
apart.
• Thin wall tubing heats up faster and causes less start-up loss
than heavy wall pipe.
• Insulating hard pipe reduces the loss in output caused by
condensation.
• When using hard pipe, take care to remove ALL traces of
lubricants used to thread the pipe. This will minimize the
possibility of tank foaming. Denatured alcohol or mineral spirits
work best for removing lubricant.

Table 25-2:
Hose kit sizing by capacity
Maximum
tube capacity
Hose kit
(steam hose, dispersion tube,
and hardware)
lbs/hr kg/h
28.4 12.9 1½" (DN40) without drain
56.8 25.8 1½" (DN40) with drain
> 56.8 >25.8
These capacities require
multiple tube assemblies and
cannot use a single hose kit.
Installation
Grounding steam pipes
The XT humidifier has built-in functionality for detecting and
eliminating foaming in the steam cylinder. However, because brief
periods of foaming are possible, grounding metal steam pipes back
to the XT humidifier earth grounding lug is necessary. This earth
ground will prevent foam from creating an electrically conductive
path from the electrically charged cylinder water to the metal steam
pipe. The grounding lug is shown in Figures 54-1 and 56-1.
