The Bryan “Low Profile” tray type deaerator is
the industry leader in compact, space saving
design. This series packs all of the same high
performance design features as other Bryan
tray type deaerators. The combination of the
Bryan tray type deaerator and the industry’s
first true 1ⴕNPSH pump has resulted in a true
space saving unit.
The overall height saved is unparalleled.
All internal surfaces that come in contact
with undeaerated water are constructed of
type 304L stainless steel for long life and low
maintenance. Tray assemblies are of welded
construction and are also made of type 304L
stainless steel.
Units are available with either simplex or
duplex pumps, and a complete range of
control options making this a total deaerator
package for ease of installation.
