• DEGASSING UNIT
It may occur that a certain amount of air is contained in the light oil sucked up by the pump. This air may originate from the light oil itself as a
consequence of depressurization or air leaking past imperfect seals.
In double-pipe systems, the air returns to the tank from the return pipe; in single-pipe systems, the air remains in circulation causing pressure var-
iations in the pump and burner malfunctions.
For this reason, we advise installing a degassing unit near the burner in single-pipe installations.
Degassing units are provided in two versions:
