DeutschDiFFS Nozzles
DiFFS Nozzles K3GS and ULP-40 series nozzles are designed to be used on Deck Integrated Fire Fighting Systems (DIFFS). An array of these nozzles installed on the helipad / helideck provides an effective spray distribution covering the whole deck surface for a range of weather conditions.
The nozzles are manufactured with orifices drilled for horizontal and vertical flow components. The nozzles do not ‘pop-up’ on the deck and instead, discharge foam from their fixed position.
The precise number and layout of nozzles is dependent on the specific helipad / helideck type, the “D” value of the deck, the flow rate of the nozzle and its coverage. As required by the standard there will be sufficient overlap of the horizontal flow components when all the nozzles are discharging during the system operation.
Since the nozzle is a non-pop-up; the condition of a blocked nozzle is not relevant (as required in CAP-437). However, if there is a blocked flow (due to a heavy object resting on top of the nozzle); then the foam will continue to flow out from the side orifices of the nozzle.
