A jet spray atmospheric deaerator unit having a vessel divided into an atmospheric section and a low pressure section, the low pressure section containing a jet spray deaerator valve connected to a steam supply line arranged with a water collection tray for deaerating water dispensed from the tray, the collection tray receiving water from the atmospheric section through a water circulating line which sprays water over the tray to purge steam from an open gas vent line communicating between the low pressure section and the atmospheric section, the atmospheric section having a vent open to atmosphere with a vent condenser to purge vented non-condensible gases from the atmospheric section, and, the low pressure section being pressure protected by a water column conduit communicating between the vessel sections to return overflow water and blow through excess pressurized gas.
