Product Description

The Model OH-Neptun series, for Type Approval called Poseidon, consist of a series of automatic low pressure watermist nozzles for semi-concealed pendent installation in ceilings (OH-L0, OH-L1, OH-L2, OH-CO, OH-CA, OH-CA1, OH-CA2 and OH-PX1 nozzles) and horizontal installation in walls (OH-SWC nozzle).

The nozzles are designed to blend perfectly into the surroundings with their semi-concealed design, and with the possibility of having them supplied in any RAL colour. The concealed design also protects the nozzles from being hit and damaged – This is a perfect match for offshore applications where the ceiling heights are often not very high.
