Guaranteed absorption distances

Using data collected in our on-site test lab, we have developed

guaranteed steam absorption distances. Performance charts allow

you to confidently choose equipment that will accommodate any

application.

Dry steam

Adding humidification to an airstream without creating wetness

in the duct system is critical for the maintenance of a healthy

environment. Wet areas in ducts are a threat to the health of

building occupants since they moisten dust on duct floors, creating

ideal breeding grounds for disease-producing microbes. In addition,

water accumulating in ducts can drip and cause building damage.

Steam escapes drip-free through tubelets

All DRI-STEEM evaporative dispersion tube units discharge steam

through thermal-resin tubelets fitted into dispersion tubes. These

tubelets extend from the center of the tube, where the steam is

driest, through the tube wall, to the duct airstream. In essence, the

tubelets provide a temperature-neutral escape tunnel for steam,

allowing steam to cross over lower-temperature metal without

condensing or dripping. Each tubelet contains a calibrated orifice

sized for steam capacity. These tubelets are a DRI-STEEM exclusive,

and are essential for drip-free steam dispersion.

Condensate drains away

Some condensation is inevitable in steam dispersion, but through

careful design, condensate can be controlled and directed away

from where it can cause problems.

For example, the Ultra-sorb dispersion panel has a unique double-

header design that uses gravity to remove condensate. Steam enters

the supply header, escapes through the tubelets, and condensate

drains out the return header. In the Rapid-sorb dispersion unit,

steam enters one end of a single bottom header with velocities

carefully managed so that condensate is not pushed out into the air

along with the steam, but rather drains out at the opposite end of

the header.

For more information about dispersion units, see Pages 9-10

and 16-23.

DRI-STEEM’s unique tubelets extend into the

center of the tube so only the driest steam

is discharged into the air.

DRI-STEEM’s dispersion tubes are fitted with

one or two rows of closely-spaced thermal-

resin tubelets to evenly disperse steam across

the airstream.
