Importrant product at MSV 2025

BJ Energy will present a patented Vibrational Compressor (Patent No. 288877) at the trade fair, which it exclusively manufactures. The device operates on the principle of centrifugal force acting on weights attached to active components of the system, such as compressor pistons, pump diaphragms, or generator cores. During rotation, these weights are pushed outward from the center due to the centrifugal force. This motion is transmitted via connecting rods to the working elements, resulting in the performance of mechanical work with exceptionally high efficiency.

This technology, based on a fundamental physical principle, represents a revolutionary approach to powering mechanical and electromechanical systems, offering significant improvements in energy performance. By adjusting the circular path and rotational speed, the system can be optimized for a wide range of applications in industry, energy production, and transportation. Key advantages over traditional drive systems include:
