separator tanks are used to remove entrained air within liquid systems,
applicable to both open and closed loop heating systems. It is important to remove
entrapped air because it reduces the heat system efficiency and precise
control of temperature. Systems using air separators often require less
chemicals for pH and corrosion control because dissolved oxygen, carbon
dioxide and other non-condensable gasses are removed from the condensate on
its way to the feed tank.
To remove the entrained air, the
condensate enters the separation tank tangentially to the vessel body,
creating a centrifugal vortex downwards towards the lower tangentially
mounted outlet nozzle (the tangential nozzle orientation accomplishes air
separation with the minimal tank body size possible). The resulting
low velocity centrifugal force propels the heavier "air free"
condensate towards the outer edges, releasing the entrained air into the center of the swirling vortex
where it can rise upwards through the vessel vent port and
float style air vent
Sediment collects within the lower dished head section and can be
periodically blown-down from the system as required.
initial system start-up it might require several passes to remove most
of the air from your system and thereafter air attributed to make-up
water will automatically be removed.
Our standard air separator
tanks are constructed of carbon steel and both designed and manufactured
in accordance with the latest edition of ASME Code Section VIII Div. I,
including code stamp. Tanks 3" and larger are offered with 150# ANSI
flanged nozzles, although as a custom fabricated vessel we can
accommodate whatever type of connection is most compatible with your
design. We have constructed air separation tanks from stainless steel
and for working pressures up to 3,000 PSIG.
