Leviathan Dynamics designs compact, high-speed centrifugal compressors embedded in modular systems that enable low-pressure water boiling and heat recovery for industrial cooling and wastewater concentration. Its patented compressors (one to two wheels, ~40 cm, 15–20 kg) operate under vacuum with steam and are integrated into chillers, heat pumps and an evapo-concentrator currently commercialized and at TRL 7. The evapo-concentrator can recover up to 80% of industrial effluent water and can reduce effluent volumes by up to fivefold, while the systems claim roughly 30% lower energy consumption versus conventional solutions. The company operates a 1,000 m2 production unit in La Courneuve and had a team of 18 employees at the time of reporting. Leviathan plans to scale manufacturing to produce 600 machines by 2030, expand its workforce to 80–100 people, and develop higher-capacity 100 kW compressors to serve larger surfaces and data-center use cases. Its technology has been tested with clients in pharma, chemicals and other industries where gentle low-temperature processing preserves biologicals and enables valorization of concentrated residues.
