K3GS series nozzles
DiFFS Nozzle - K3GS 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 K3GS series 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.

DiFFS system design
DiFFS system is primarily used as a firefighting system for helipad / helideck. Based on the system configuration, DiFFS can be set to operate automatically or manually. On system activation; a valve operates - allowing water to flow through a water turbine foam pump or inline inductor thereby discharging a correct admixture of foam/water solution (i.e. 1% or 3%) through an array of nozzles installed on the helipad / helideck, thus providing an effective spray distribution covering the entire deck surface.
