For single-pipe installation with automatic oil burners with bypass oil-air separation to DIN EN 12514 and TRD 411 & 604.
Details and applications
1. Ball valve
2. Filter
3. Adapter for oil meter (VZO)
4. Pressure-equalisation device
(safety valve)
5. Vessel with:
5.1 Manual ventilation
5.2 Tank drain
6. Manometer with ball valve
7. Oil pan
10. Oil meter model VZO
11. Pressure switch (S)
12. Automatic float air vent (G/SE)
13. Time-controlled vessel vent (TE)
14. Leakage detector integrated into oil pan (LH)
Via the T connection the medium is conveyed through the fitting with system pressure (0.5 – 5 bar) via ball valve 1 and filter 2.
The burner pump extracts the medium from the vessel via T1 connection and returns the burner bypass quantity via R connection to the vessel.
In the vessel, the air is separated from the medium and is separated off out of the system via manual ventilation 7 (optionally other ventilation options 12 and 13).
To avoid unpermitted high system pressure, a pressure equalisation device 4 (safety valve) is integrated.
