Balder PO portable oscillating monitor

Description

Balder is a 2½” monitor for portable use. It is self-oscillating and powered by water flowing through a special oscillating mechanism. Balder automatically sweeps from side to side. The speed of the sweeps and the elevation could be manually set and also be varied during operation. It is also possible to use the monitor without the oscillation and manually adjust the stream within 180° angle. Balder has a water inlet with a 2½” BSP thread. For flows above 1,500 liters it is equipped with a double inlet.

The pipes are casted in anodized aluminium. Parts which are vital for the correct functions, such as swivels are in stainless steel. Innovative piping technology minimizes turbulence and frictional pressure losses. Balder is compact and weighs only 10.6 kg.

Operation

The fire hose should be connected and put in a circle around the monitor. If two fire hoses are used one of them should be connected and put into a circle. The fire hose stabilizes the monitor. The two spikes and the water inlet at the front compensate the reaction forces, and keeps Balder standing alone. Adjust the elevation and the speed of oscillation. Balder works at low temperatures also at the lowest speed of oscillation.
