Hydrosun Medizintechnik Gmbh

What Hydrosun Medizintechnik Gmbh does

Hydrosun Medizintechnik GmbH is a privately held German medical device manufacturer (GmbH) founded in 1994 and headquartered in Müllheim, Germany. The company develops, manufactures, and distributes therapeutic devices based on its proprietary water-filtered infrared-A (wIRA) radiation technology, operating in the 590-1400nm wavelength range. Its core innovation is a patented hermetically sealed liquid filter (Küvette) that absorbs skin-damaging wavelengths at 944nm, 1180nm, and 1380nm, allowing only deep-penetrating, skin-friendly infrared-A radiation to pass through, enabling deeper therapeutic tissue warming without surface burns.

The product portfolio comprises seven device lines: the hydrosun575 and hydrosun750 professional radiators for medical practices; the hydrosun575home certified for domestic use under EN 60601-1-11; the PhotoDyn750 for dermatological photodynamic therapy; the hydrosun TWH1500 for oncological thermography-controlled wIRA hyperthermia; the heckel-HT3000 whole-body hyperthermia system (co-developed and manufactured for heckel medizintechnik GmbH which holds exclusive worldwide distribution rights); and the hydrosun colours HC7 accessory for chromotherapy. All active devices are classified as Class IIa medical devices under Directive 93/42/EWG (Annex IX Rule 9), and the company maintains a DIN EN ISO 13485 certified quality management system with full compliance to EU MDR 2017/745; certification is held via TÜV SÜD Product Service GmbH (Notified Body 0123).

Hydrosun operates a hybrid go-to-market combining direct sales from Müllheim for Germany with a structured network of specialty distribution partners (e.g., S-L.E Germany for dermatology, heckel medizintechnik for hyperthermia, MedCare Visions for neonatology/pediatrics) and exclusive country-specific international distributors spanning 15+ markets across Europe, East Asia, Southeast Asia, and Oceania. Revenue is generated predominantly through one-time device sales supplemented by a recurring annual safety technical inspection (STP) service mandated for active Class IIa devices, plus technical support and filter-related maintenance. Pricing is not publicly disclosed; customer acquisition relies on a DocCheck-authenticated professional portal for clinical content (required by German HWG), website presence, and partner-led field activity across medical specialties including rheumatology, dermatology, oncology/hyperthermia, neonatology, physiotherapy, and home-use segments.

Core offering

Hydrosun Medizintechnik GmbH develops, manufactures, and distributes Class IIa medical devices that deliver water-filtered infrared-A (wIRA) radiation for therapeutic deep-tissue warming. Its portfolio includes stationary and home-use wIRA radiators (hydrosun575, hydrosun575home, hydrosun750), the dermatology PDT device PhotoDyn750, the oncological hyperthermia system hydrosun TWH1500, the whole-body heckel-HT3000 hyperthermia unit, and the hydrosun colours HC7 color filter accessory. All devices leverage the company's patented liquid-filter (Küvette) technology that removes skin-damaging wavelengths at 944nm, 1180nm, and 1380nm to enable deeper, safer infrared-A penetration.

Product overview

Hydrosun Medizintechnik GmbH offers a portfolio of therapeutic medical devices based on water-filtered infrared A (wIRA) radiation technology operating in the 590-1400nm wavelength range. The core product line consists of portable hydrosun-brand infrared radiators (hydrosun575, hydrosun575home, hydrosun750) designed for medical practices and home use, featuring patented liquid filter cuvettes that remove skin-damaging wavelengths while enabling deep tissue penetration. Specialty devices include the PhotoDyn750 for dermatological photodynamic therapy and the hydrosun TWH1500 for oncological hyperthermia. The portfolio also includes the heckel-HT3000 whole-body hyperthermia system (co-developed/co-manufactured with heckel medizintechnik GmbH) and the hydrosun colours HC7 color therapy accessory. All devices utilize the company's proprietary wIRA technology, which filters infrared radiation through water to remove harmful wavelengths while preserving therapeutically effective deep-penetrating infrared A radiation.

Direct peers

• Beurer GmbH (Bioptron): Beurer's Bioptron light therapy device line operates in the medical light therapy segment close to Hydrosun's wIRA therapy portfolio (chronic pain, wound healing, dermatology). Both target professional clinics and home users with non-pharmacological phototherapy modalities, although Beuron's technology is broad-spectrum light rather than water-filtered IR-A.
• Pyrexar Medical: US-based manufacturer of superficial and deep regional hyperthermia systems used adjunctively with radiation therapy for cancer treatment. Highly comparable to Hydrosun's hydrosun TWH1500 and heckel-HT3000 hyperthermia products, competing in oncological hyperthermia where Hydrosun is recognized under ESHO guidelines.
• Oncotherm Kft. Hungarian/German manufacturer of capacitive hyperthermia devices used in oncological supportive care. Operates in the same oncology hyperthermia space as Hydrosun's TWH1500 and heckel-HT3000 systems, addressing similar reimbursement and clinical guideline challenges.
• heckel medizintechnik GmbH: German MedTech company and Hydrosun's joint development partner for the heckel-HT3000 whole-body hyperthermia system. heckel exclusively distributes this Hydrosun-manufactured product worldwide and also partners on surface wIRA hyperthermia, making it both a strategic ally and the closest comparable specialty hyperthermia/infrared therapy peer.

Regional players

• AquaBera / infrared sauna manufacturers (e.g., Clearlight, Sunlighten): Adjacent infrared therapy manufacturers primarily serving the consumer/spa and home wellness market rather than certified Class IIa medical use. Less directly comparable to Hydrosun's certified medical wIRA devices but occupies the adjacent "infrared therapy" market Hydrosun's competitors and patients may compare against.

Broad incumbents

• Biofrontera AG: German dermatology-focused specialty pharma/medical device company selling photodynamic therapy products (Ameluz, BF-RhodoLED). Comparable to Hydrosun's PhotoDyn750 in PDT for dermatology indications, though Biofrontera is larger and pharma-led vs Hydrosun's device-only focus.
• Lumenis (Boston Scientific): Global leader in energy-based medical devices including IPL, laser, and phototherapy systems for dermatology and aesthetics. Comparable at the technology/use-case level (light-based dermatology therapy) to Hydrosun's PhotoDyn750 PDT device, though at much larger scale and broader portfolio.

Emerging players

• Medtherm GmbH: German specialty manufacturer of thermometry and hyperthermia-related medical equipment used in oncology and physiotherapy. Comparable niche MedTech peer addressing overlapping clinical and regulatory territory with Hydrosun's thermography-controlled wIRA hyperthermia device line.
• PhotoNova / Repuls Lichtmedizintechnik: Austrian/German specialty manufacturer of medical cold-light and infrared therapy devices used in dermatology and wound care. Compares to Hydrosun on technology (filtered light/infrared for therapeutic purposes) and customer base, though with a narrower focus and no wIRA technology.
• Verilux (Verilux Holdings): Manufacturer of clinical and consumer light therapy devices including infrared therapy units. Overlaps with Hydrosun's wIRA product positioning for pain, wound, and inflammatory indications, though Verilux's products are largely non-medical-grade consumer devices.
