The drawings below show how increasing the number of steam discharge

points and/or number of dispersion tubes shortens absorption distance.

Single-tube dispersion

Of the three examples shown here,

the single-tube covers the smallest

percentage of the airstream and has

the longest absorption distance.

RAPID-SORB dispersion

With the same conditions, absorption

occurs in a shorter distance with a

multiple-tube dispersion assembly

because it has more steam discharge

points and it covers almost all of the

airstream.

ULTRA-SORB dispersion

With the same conditions, this

dispersion assembly provides the

shortest absorption distance. It

has multiple tubes, two rows of

discharge points on each tube, and

an additional header for managing

condensate, allowing increased

capacity.

Typical absorption distance

approximately 48" (1.2 m)

Typical absorption distance

approximately 18" – 48" (0.46 m – 1.2 m)

Typical absorption distance

approximately 6" – 24" (0.15 m – 0.60 m)

Evaporative steam absorption comparison

be present. Solid objects at duct air temperature, such as coils,

dampers, fans, etc., downstream of this dimension will remain dry.

When installing upstream of high-efficiency filters, visible

condensed steam wisps entering the filter bank can result in a

wetted filter. If you need to install upstream of high-efficiency

filters, consult your representative or DRI-STEEM directly for

special recommendations.
