The arm nozzle and the new spike nozzle
The arm nozzle has been developed for fire service and compartment fire extinguishing needs and it complements and can sometimes replace traditional fire nozzles. In our experiments, we have seen that in many cases it is clearly more efficient than a traditional nozzle. Main motivation for the arm nozzle has been the ability to extinguish the fire from outside thus radically decreasing the exposure to carcinogenic substances in the smoke.
The nozzle can also be used in vehicle fires and battery fires of electric vehicles.
