Hitachi Industrial Equipment Systems Energy Recovery System
Hitachi Industrial Equipment Systems
Recovery of unused hydraulic energy into electricity, energy recovery system using inline water turbines.
Overview There is energy available here as well. Would you like to utilize untapped hydro energy? Currently, as global efforts to address the issue of global warming are underway, there is a growing demand for the effective use of clean, untapped energy that has a low environmental impact and fewer resource constraints. Hitachi proposes an "Energy Recovery System" that recovers untapped hydro energy, which has been overlooked until now, into electrical energy using a power generation water turbine. The recovered electricity can be used to reduce the power for equipment or for various applications such as lighting and hot water supply. Since the revised Energy Conservation Act came into effect, the demand for energy conservation has been increasing. Hitachi responds to customer solutions with the Energy Recovery System. The "Energy Recovery System" achieves high-efficiency energy recovery through optimal rotational speed control of the turbine based on the effective head, and it adopts a generator-integrated inline turbine that can be installed in the middle of piping, realizing a compact and small design. This product, which combines our fluid technology, motors, and control technology, is characterized by its ability to achieve high recovery of untapped energy with the aim of reducing environmental impact. High efficiency with an energy recovery rate of approximately 60% For example, with an effective head of 35m and a flow rate of 2.8m³/min.
