Humidifier Dimensions
(Continued from page 2)
Steam Pipe Capacities
For computing ability of piping to deliver an adequate supply of steam to humidifier.
Capacities shown are in pounds per hour.
14
Steam humidifiers (or other
products) should be installed in
locations that allow routine
inspection and accessibility for
maintenance operations.
Armstrong recommends that steam
humidifiers not be placed in
locations where unusual instances
of malfunction of the humidifiers or
the systems might cause damage
to non-repairable, irreplaceable, or
priceless property.
