For single-pipe installation with monoblock burners and systems according to DIN 4755 BI.2 and TRD 411 or 604. These fuel oil air-separation units are to be considered as a component of a burner unit and designed for a max. pressure of 5 bar.
by means of separate feed pump through the ring main present or tank situated higher up.
For single-pipe oil installation of automatic oil fuel with fuel oil EL suitable for systems to DIN 4755 or TRD.
Design according to scheme A (with supply pressure on T connection)
The burner pump shall supply the oil via a ball valve , filter, adapter for oil meter (or optionally integrate oil meter ) and vessel in the single pipe system, i.e. in T connection, only the fuel oil used by the boiler flows. In T1 and R connections, on the other hand, the full intake flow of the burner pump flows. The bypass oil R coming from the burner is directed via the vessel back to the burner. The air arising as a result may be vent by manual ventilation.
Optionally, automatic vent by a float air vent is also possible.
This unit is designed for supply pressure of 1 – 5 bar.
Other designs (e.g. for suction operation or deviating accessories) may be provided on request.
