Fluidics Instruments has made atomisers in Eindhoven since 1977. The company develops and builds nozzles, burner lances and regulators for oil burners, and likes to be in on the engineering early. Its spill-back atomisers, the return-flow type, come in three sizes from 8 to 2,250 kg/h and include the W1 and W2 types fitted on Oilon burners.
Arne Nielsen A/S supplies the full Fluidics range as an official dealer and keeps the common W1 and W2 return-flow nozzles on the shelf. Many of these are the same parts Oilon fits from the factory: a 12-W2-145-60 is Oilon 34031250, a 12-W1-250-50 is Oilon 34031309.
Send the nozzle code stamped on the body (type, capacity and spray angle) or simply the burner make and model. We match the right Fluidics part and ship to agents, ports, shipyards and vessels worldwide.
