Global manufacturer Mavel has added a modular micro-hydro turbine to its TM line with the introduction of its TM8 model. Mavel said each unit has a capacity of 20 kW to 100 kW and this technology is designed for installation on low-head facilities such as weirs and irrigation systems, without the need for an enclosed powerhouse. Each TM8 unit includes a Kaplan-type runner with four manually-adjustable blades, an 850 mm runner diameter, an operational head of 2 to 5 meters, and a flow of 52 to 106 cubic feet per second. Other models in this line include the TM3,TM5 andTM10, which the company says have been installed at more than 60 sites around the world.
