Fully Compliant & Certified

When it comes to hyperbaric oxygen therapy, safety and reliability are non-negotiable. That’s why every Oxy-Stack chamber is built and certified to meet the world’s highest medical and engineering standards. Our systems are fully certified under EU 93/42/EEC and compliant with the MDR (EU) 2017/745 regulation, ensuring genuine medical-grade performance. We adhere to EN 14931 standards and observe IMCA, DNV, and GL guidelines for operational integrity. Each chamber is constructed as a certified pressure vessel in accordance with 2014/68/EU (PED) and the ASME PVHO-1 (Pressure Vessels for Human Occupancy) standard — the global benchmark for hyperbaric safety. Manufacturing takes place under ISO 13485 and ISO 9001 quality management systems, guaranteeing precision and consistency at every stage. For enhanced protection, our systems incorporate a fire suppression system certified to NFPA 99 standards and are tested for EMC & LVD TS EN 60601-1 compliance.

Luxury & tailor-made

Beyond safety, Oxy-Stack chambers feature spacious, high-end interiors that redefine the therapy experience. Each includes a reclining electric chair, allowing guests to lay back and relax throughout their session. Medical-grade leather upholstery comes as standard, merging hygiene with luxury, while the cabin offers ample room to watch a movie, listen to music, or even catch up on work, making every session both restorative and productive.

Every Oxy-Stack is also fully customisable, allowing estasblishemnts to tailor the chamber to their environment and brand. Choose from a selection of bespoke exterior colours, premium interior leathers, and design finishes, transforming the system into a statement of wellness and style.

In addition to our established design portfolio, we offer fully bespoke chamber builds, collaborating closely with architects, designers, and clients to realise distinctive concepts that merge advanced engineering with timeless luxury.

Immersive Sound Therapy — Exclusive to Oxy-Stack

The deeply immersive sound experience first introduced within the KOKOON is now integrated into our Oxy-Stack hyperbaric chambers, an exclusive combination of technologies designed to transform every session.

Carefully engineered soundscapes, therapeutic frequencies and subtle vibrations work with the nervous system to encourage a shift away from stress and into a calmer, restorative state. As the body relaxes, breathing naturally becomes steadier, muscular tension softens and the mind is given space to switch off.

Combined with the pressurised oxygen environment of HBOT, sound creates a powerful multi-sensory experience, supporting deeper relaxation and complementing the therapy being delivered. The result is more than a hyperbaric session: it is an immersive recovery experience for both body and mind, available exclusively within Oxy-Stack chambers.
