3. STEAM RUNS AND CONDENSATE RETURNS
A.
STEAM RUNS
(1) Steam runs between the humidifier and the distributors can be accomplished by using
flexible NORTEC steam hose or insulated copper pipe. The longer the steam run,
including elbows, the lower the efficiency of the system. The more elbows and turns,
the higher the losses become. The humidifier should be as close as possible to the
distributor and the steam run should be as direct as possible.
(2) Guidelines for installation are:
(a) Locate humidifier as close as possible to the duct system.
(b) NORTEC steam hose should only be used on short steam runs below 10 feet.
(c) Minimize elbows and turns.
(d) Ensure that no condensate produced in the steam line will remain trapped. Steam
naturally flows upward and condensate naturally flows downward. Always slope
the steam run towards the steam source at a 15°
pitch no more (See Figure 5.).
(e) Oversize condensate line and steam line of long runs (consult your
representative).
(f)
See material recommended for use in Table 11. To eliminate corrosion, NORTEC
does not recommend the use of steel piping.
(g) Consult Table 12 and Table 13 for steam and condensate sizing guidelines when
using steam distributors.
