Afriso oil de-aerator, FloCo-Top-2KM Si

Afriso FloCo-Top-2KM Si is suitable for single-line systems with return flow feed in oil fired systems for continuous de-aeration. The de-aearator is suitable for the following media: heating oil EL (DIN 51603-1) and diesel fuel (EN 590) as well as organic heating oil (EN 14213) and organic diesel (EN 14214) with max. 20% FAME. Also suitable for areas liable to flooding. Multiple filtration is recommended for burners with an oil consumption of < 20 l / h, while larger systems should be operated with single filtration. Automatic heating oil de-aerator in safety version, with integrated filter, stop cock and vacuum pressure gauge for indication of pump vacuum and degree of filter pollution (increasing vacuum). Housing with changeover valve for multiple filtration as well as backflow preventer with integrated pressure relief towards the tank. De-aerator hood with triple float safety system to prevent oil foam from escaping via the de-aerator opening. For venting, the return oil is guided via the float chamber and can be then be added directly to the supply or it can be filtered again by switching over a valve. In case of multiple filtration, the return oil increases the flow rate so that the filter cup is permanently filled with de-aerated oil. In service mode, the vacuum pressure gauge indicates the pump vacuum. The stop clock can be closed to check the suction capacity of the burner pump. Increased vacuum provides information on  the degree of the pollution of the filter. The drain unit ensures that replacing the filter is easy and clean: Connect the hose, open drain valve, loosen the lock nut of the filter cup and drain the oil in a controlled way. When the burner hose needs to be changed, it is sufficient to open a bypass valve so that the oil is drained from the float chamber via the filter cup and the drain unit. Water pressure-tight up to 10 m water column.   Technical data: Burner connection: G 3/8" ET with 60° cone for burner hoses Tank connection: G 3/8" IT Nozzle capacity: max. 100 l / h Return flow: max. 120 l / h Separating capacity air / gas: approx. 4 l / h Mounting position: float chamber vertically upwards Operating temperature range: medium: max. 60° C ambient: max. 60° C Operating overpressure: max. 0.7 bar (corresponds to static oil column of approx. 8 m) Test pressure: 6 bar Vacuum pressure gauge: range: 0.7 / +0.9 bar
