The PowerPal LowHead turbines series MHG-200/500/1000LH are used for locations with only low head (1.5m) and comparatively big water flow (35 - 130 l/s).

Besides, the water is taken from a stream at a suitable place (waterfall, fall) or an artificially created dam and is supplied with a canal to the turbine. A rake at the beginning of the canal prevents the entry of sluice (foliage, branches...) in the canal. The length of the canal depends on the available slope of the river, so that the canal must be led at least so far that the head is reached at it´s end. Besides, the cross section of the canal should be so big at least like the cross section of the PowerPal intake canal box:

The slope of the canal should move in an area between 0.1% and 0.5% of the length (e.g., 50-m canal length ~ 5 - 25 cm of slope). With pleasure we calculate to you the slope necessary for your project. At the end of the canal, the water is supplied to the PowerPal intake canal where it passes the turbine and afterwards the suction tube. A fundamental construction of such a turbine arrangement (here: MHG-500LH) with the PowerPal intake canal and suction tube as well as this "all around" is clearly shown on the next sides.
