AREA-TYPE Humidifier Application
Information
The operating characteristics of AREA-TYPE steam
humidifiers should be considered when selecting humidi-
fier capacities and choosing mounting locations.
Steam discharge from the humidifier quickly cools and
turns to visible, warm, microscopic drops or particles of
water (fog) which are lighter than air.
Should this fog contact any solid surface (columns,
beams, ceiling, pipes, etc.) before it disappears, it may
collect and drip, as water.
The greater the space relative humidity, the higher and
farther the "fog" will carry and rise in the space before
disappearing.
The table at right states the vertical (rise), horizontal
(throw), and width (spread) dimensions that can be
expected with the AREA-TYPE humidifiers.
To avoid steam impingement on surrounding areas, these
dimensions should be observed.
Note: Tank dimension "C," in figure 5-1 on page 5, must
be at least 12.85" (325 mm) and output should not exceed
285 lbs/hr (130 Kg/h).
