2-cell cross-flow water turbine

2-cell cross-flow water turbine

Proven high quality with over 10,000 units accumulated! Easy installation and minimal civil engineering work.

The product can operate for long periods with almost no maintenance required. It does not need expensive and complex spare parts for operation, allowing for maintenance work at the power plant. Additionally, a special advantage is that it causes water hammer effects in long water supply systems and does not negatively impact the water supply system due to mechanical operation. Furthermore, it has high maintainability and strong resistance to foreign substances. 【Advantages】 ■ High-efficiency operation over a wide range of flow rates from 12% to 100%, resulting in significant annual power generation ■ The flow rate required for startup is only 6% ■ A versatile range of models adapted to specific locations ■ Runner that is less prone to clogging ■ High adaptability to changes in drop height *For more details, please refer to the PDF document or feel free to contact us.

Open-type small hydropower generation system WaterWeco (R)

Open-type small hydropower generation system WaterWeco (R)

A small hydropower generation system that can generate electricity efficiently even with low head and low flow.

Even with fluctuations in flow, stable power generation is possible. Maintenance is easy (measures against debris are straightforward). Fish passages can be secured, allowing for consideration of biodiversity. Additionally, since it effectively utilizes flow velocity, there is minimal waste of energy, and the risk of overflow is extremely low.

Open-type small hydropower generation system WaterWeco®

Open-type small hydropower generation system WaterWeco®

The WaterWeco® micro-hydropower generation system, which offers unprecedented ease of maintenance and stable power generation even in low head and low flow environments.

Sustainable decentralized energy suitable for the natural environment WaterWeco® can generate stable power with minimal fluctuations through its unique patented mechanism, day and night, throughout the year. This initiative involves installing water wheels in agricultural and industrial waterways scattered across various regions to effectively utilize natural energy. By conducting repeated demonstration experiments with numerous municipalities, universities, and research institutions, we mainly handle systems ranging from a few watts to 20 kW per unit. In wide waterways, it is possible to increase power generation by increasing the number of units through parallel installation. Since the mechanism does not negate the kinetic energy of water with weirs or similar structures, it can be directly transmitted to the water wheel (the risk of overflow is also extremely low). Additionally, it is possible to ensure fish passages that consider biodiversity (though this requires prior ecological understanding and consultation with experts, depending on the species).
