FeTu Limited

FeTu Limited is an innovation-driven enterprise based in West Yorkshire that has developed a proprietary roticulating fluid machine. This novel technology, described as the world's first quad-acting device, functions as a positive displacement low-velocity turbine. It uses a unique twin-suction and twin-discharge architecture with only two moving parts to operate four anti-phased compression chambers. By offering a lightweight, scalable, and highly efficient method for converting energy, the system is designed to perform various roles, including compressing, expanding, pumping, and power generation across multiple industrial and clean energy sectors.

The technology is targeted at driving mass cross-sector decarbonization by enabling efficient thermal energy harvesting, such as from solar and geothermal sources, and providing solutions for industrial applications including refrigeration, automotive, and power generation. FeTu has focused heavily on protecting its intellectual property portfolio and has successfully demonstrated its compressor technology to TRL 6 through collaborations with institutions like the Advanced Propulsion Centre. The company continues to work with commercial, technology, and investment partners to refine its R&D and scale the application of its core architecture for sustainable energy challenges.
