The pneumatic systems are commonly used in industrial plants to power pneumatic machines and tools. However, since production of compressed air is quite expensive, manufacturing plants are trying to reduce the operating costs of pneumatic systems by improving their energy efficiency. There are three main methods of reducing costs in these systems: averting energy losses, limiting input energy and harvesting energy wastes of compressed air. In this article, the authors focus on the last method mentioned above - recovering energy wastes from cutting line of electrical steel in a production plant, by using their own invention. The maximum power Pe of the device is changing from 190 W to 60 W and it depends on the value of overpressure in the tank. In one hour, the device generates about 0.07 kWh energy and uses about 3.8 m3 of air in overpressure of 6 bar.
