The Bryan tray type deaerator is unsurpassed in
performance and reliability. These units are
ASME Code pressurized units, and are guaran-
teed to deliver deaerated water at a maximum
oxygen content of .005cc/l (7PPB) and zero
measurable CO . All internal surfaces that
2
come in contact with undeaerated water are
constructed of type 304L stainless steel for long
life and low maintenance. Their long residence
time makes them readily adaptable to all
systems, even where wide load swings occur.
A complete line of boiler feedpump and
control packages is available making the Bryan
tray deaerator a completely packaged unit
ready for installation with the minimum amount
of field assembly.
