Micro hydro power eqipment using water pipes has high energy density, low cost compared to wind power generation, and can secure stable quantity. Existing hydroelectric power generation requires a free-floating structure, but the water supply pipe type Micro hydro power eqipment is a system that generates power by using the flow rate flowing through the water supply pipe and the surplus head of the water supply pump. In addition, the vortex aberration model can be applied to the low free fall discharge channel, and the bed type water turbine power generation model using a helical turbine can be used for the open channel. Each generator model is a patented product, and Reentech Engineering supplies the entire system including a water turbine generator and control system.
