エリス Company Profile

The load-following open-type small hydropower generation WaterWeco(R) can contribute to the environment with low head (over 1.5m) and low flow (over 1.0cms).

The output mainly supports a range of 5 to 100 kW. Due to unitization, parallel installation is possible. (Note: Strength calculations may be necessary depending on the flow rate.) Brief history: From 2009, collaborated with municipalities such as Okayama City, Tsuyama City in Okayama Prefecture, and Miri City in Hiroshima Prefecture, as well as consulting companies for feasibility studies (demonstration experiments), owning power generation and self-consumption facilities, conducting long-term operational tests, and improving power generation efficiency, with support from the Okayama Prefectural Industrial Promotion Foundation and Nagasaki University Graduate School of Engineering, a fluid research institution, and Nishinihon Fluid Technology Co., Ltd. for collaborative research, optimization, product development, and completion of actual machine installation operations. Patents were registered in October 2020 (including other overseas patents in Europe and the United States, the WaterWeco® trademark, and design registration for the water turbine blade shape). *Installation is possible in suitable locations where installation was previously impossible due to overflow risks. ★ Labor-saving ➣ Easy measures against debris and heavy snowfall (no dust removal device required) ➢ Significant reduction in maintenance costs (initial costs). ★ Automatic layout control mechanism adjusted to flow rate fluctuations ➢ Stable power generation efficiency during the period. ★ Consideration for biodiversity ➣ Even when installed in rivers where fish migrate, fish passages can be secured. ★ Awards and technology registration history: Various awards including the Eco-Products Award and the Chairman's Award from the Invention Association, and registration with UNIDO STePP.
