Niagara Self-Oscillating Monitor

Niagara Self-Oscillating Monitor supplied by SA Fire Protection

Model UAS is a universal self-oscillating unit that is installed at the base of manual monitors in order to gain an automatic oscillating movement on the horizontal plane. The unit UAS is powered by a Pelton turbine that transform the energy of water pressure into a rotating movement. This rotation is then converted by a gear box in rotating alternative on the horizontal axe of the monitor itself.

The oscillating movement can be adjusted in a range of 0° to 360°. The material of construction makes it suitable for being used with sea water or water foam solution within industrial harsh environments & offshore applications.
