9. If steam line is routed below steam distributor
or if the steam distributor is lower than the
humidifier, a condensate trap “tee” will be
required to remove water at this low point.
Run condensate from trap to nearest drain
lower than the distributor. See Figure #24.
10. Do not run steam line more than 1 foot per
lb/hr output. Example, 10 lbs/hr should not
have a steam run longer than 10 feet. If long
runs are unavoidable, the humidifier should be
sized larger to compensate for condensate
losses and insulated copper should definitely
be used.
NOTE FOR OUTDOOR ENCLOSURE: It is
recommended to insulate steam lines between
the enclosure and the building or air handling
unit specifically if freezing conditions may
occur.
WATER TRAP
1. The GH Series humidifier produces steam at
atmospheric pressure. Pressure head must
develop to push steam through supply line and
into air duct.
2. Combined resistance of duct positive static
pressure and steam line resistance creates a
small pressure head in water tank. Total
amount of positive static pressure head is
reflected directly by water column differential
that develops in the built in water trap.
3. The built in water trap allows a maximum of
4.5" W.C. pressure before tank water escapes
through drain. This pressure should not be
exceeded.
4. Static pressure is usually higher when
distributor's steam outlets are faced upstream
in a duct.
CONDENSATE RETURN LINES FOR STEAM
DISTRIBUTORS
1. Nortec steam distributors and blower packs
have built-in connections for draining off
condensate. These condensate lines must be
connected to the nearest floor drain or to a
condensate pump (available from NORTEC).
A flexible condensate hose, (available from
NORTEC), may be used for short condensate
runs.
2. Always incorporate a trap in routing of
individual condensate return lines.
Condensate that accumulates in trap will
prevent possibility of steam escaping. Depth
of trap must exceed duct static pressure in
inches of water column. See Figure #25.
3. Ensure the trap is 3’ minimum under the
steam distributor and have the trap as close to
the floor drain as possible.
4. Provide a “U” trap in condensate line even
when distributor is located in return air
plenum. It stops a suction action from
impeding condensate flow with duct pressures
below atmosphere.
