National Small Hydropower Generation Conference in Saitama

There are extremely few malfunctions because there are no moving parts! Small hydropower generation's success hinges on dust removal.

The "JJS-C" is a non-powered, non-electric debris removal system with a high capacity for removing waste such as fallen leaves and driftwood, which increases power output through full water intake and improves the operating rate of the water turbine. By simplifying the structure, initial costs are reduced. Backflow occurs due to the closing operation of the water turbine's guide vanes and valves, contributing to a reduction in maintenance burden by washing away debris. 【Features】 ■ Reduced initial costs ■ Increased efficiency by combining screens at two angles ■ Reduced maintenance burden *For more details, please refer to the PDF materials or feel free to contact us.

• Other power generation

Install in rivers and simplify equipment! Reduce maintenance costs by decreasing cleaning frequency!

The "JJS-A" is a product that can be installed on river dams. By installing it in rivers, it simplifies the equipment up to the head tank. Small hydropower generation is determined by the removal of debris, and it is a strong ally for small hydropower generation and agricultural water intake. Additionally, since there are no moving parts, the likelihood of failure is extremely low, and debris flows downstream in the river, eliminating the need for debris disposal. 【Features】 ■ Reduces initial costs ■ No power or electricity required at the intake ■ Reduces maintenance costs ■ Decreases the frequency of cleaning the intake *For more details, please refer to the PDF materials or feel free to contact us.

• Hydroelectric power

Achieving stable water intake and easy maintenance! The birth of a strong ally for small hydropower generation and agricultural water intake.

The "JJS-B" is a non-powered, non-electric debris removal system that removes leaves and driftwood from waterways, ensuring a stable water intake volume while achieving low installation and operational costs. Thanks to its special structure that minimizes clogging and considers maintenance, it achieves both stable water intake and easy upkeep. It can be installed more easily compared to conventional debris removal devices, thereby reducing the overall introduction and operational costs of the facility. 【Features】 ■ Special structure that minimizes clogging ■ Easy maintenance ■ Reduced installation and operational costs *For more details, please refer to the PDF document or feel free to contact us.
