Stage 2 – Steam Distribution Installation
Maximum steam velocity in a pipe should not exceed 40 feet/sec (12m/s)
velocity. Velocities above this will generate noise.
Minimum steam pipe gradient should be 7˚ i.e. 5'' (125mm) rise in 40'' (1m) run.
The lowest point of any steam hose or rigid pipe must be the humidifier. A
steam separator (S trap) should be installed higher than the static pressure of
the system by at least 2'' (50mm).
Total length of the flexible steam hose should not exceed 16 feet (5 m) or
insulated rigid piping should not exceed 50 feet (15 m).
Whenever possible use rigid copper piping, flexible steam hose can be used for
short runs or for interconnecting between rigid pipe runs, ensure that there is no
kink in the flexible hose.
When using rigid copper pipe, insulation should be used to diminish
condensation build up.

Connection pipe sizes between SKG3 and steam distributor in the duct should
be :

3'' (76mm) up to 264lb/h (120kg/h)

4 ¼'' (108mm) up to 528lb/h (240kg/h)

5 ¼'' (133mm) up to 560lb/h (255kg/h)
All Humidifier below 220lb/h (100kg/h) capacity should use standard Neptronic®
SAMB E2 Steam distribution pipes, Multi-Steam can be offered if shorter
absorption distances are required.
All Humidifiers above 220lb/h (100kg/h) capacity should use Multi-Steam.
All Humidifiers above 528lb/h (240kg/h) should use 2 Multi-Steam units per air
handling unit (AHU) or air duct with an equal duty split to each Multi-Steam
