Hydrosun

Hydrosun is a German medical device company focused on therapeutic light and heat systems based on water-filtered infrared-A (wIRA) and visible light. The company has been active since 1994 and develops, manufactures, and distributes hydrosun® radiators and related devices for use in clinics, medical practices, and some home-care settings. Its products are used across wound healing, pain, rheumatology, regeneration, and other supportive therapy applications, and the company also markets specialized systems such as PhotoDyn® for photodynamic therapy. Hydrosun emphasizes scientific and clinical research around wIRA and operates under an ISO 13485 quality management system. Overall, the business is best characterized as a commercial medtech company built around a proprietary therapeutic irradiation platform rather than a drug-development biotech pipeline.
