RedCel Hard Hyperbaric Chamber — Duo+ (2 Person)

Multi-Person Clinical-Grade 2.0 ATA Hyperbaric Oxygen Therapy

Designed for high-throughput clinics, rehabilitation centres, and professional performance facilities

The RedCel Duo+ Hard Hyperbaric Chamber is a large-capacity, 2.0 ATA clinical hyperbaric system engineered for professional medical, rehabilitation, and elite performance use.

With capacity for up to two people, a reinforced stainless-steel round chamber, and dual high-flow oxygen delivery, the Redcel Duo+ is designed for busy clinics and recovery centres requiring consistent performance, exceptional safety, and the ability to treat multiple users simultaneously.

It is important to note that on the Redcel Duo+ both users can sit by side by side and can therefore both sit or recline fully when using the chamber whereas with the Redcel Duo both users sit face to face and can only sit. 

Why the Redcel Duo+?

Operating at 2.0 ATA, the Redcel Duo+ delivers true clinical-grade hyperbaric oxygen therapy (HBOT)—allowing oxygen to dissolve directly into blood plasma and reach tissues that cannot be adequately oxygenated under normal atmospheric pressure.

Compared to mild or soft chambers, this enables:

• Deeper tissue oxygenation

• Faster healing and recovery

• Reduced systemic inflammation

• Enhanced neurological oxygen delivery

Hard chambers operating at 2.0 ATA are considered clinical-grade and should be operated under professional supervision.

Key Benefits

🫁 High-Capacity Clinical Oxygen Delivery

Dual oxygen concentrators deliver up to 20 L/min, supporting multiple users without compromising oxygen saturation.

🏥 Built for Professional & Medical Use

Designed for high-volume hyperbaric clinics, rehabilitation centres, and medical environments.

🧠 Neurological & Cognitive Support

Used in professional settings for post-concussion protocols, TBI rehabilitation, stroke recovery, and cerebral oxygen optimisation.

💪 Accelerated Healing & Recovery

Supports tissue repair, stem-cell mobilisation, collagen synthesis, and inflammation reduction.

⚡ High-Throughput Performance Recovery

Ideal for sports teams and recovery centres treating multiple athletes in parallel.

🌿 Longevity & Systemic Wellness

Supports immune health, cellular regeneration, and long-term wellness outcomes.

Round Hard-Chamber Design

The Redcel Duo+ uses a round stainless-steel chamber structure, which offers:

• Greater pressure stability

• Reduced structural deformation

• Lower operational noise

• Enhanced long-term durability

Large viewing windows and a wide sliding door create a bright, accessible interior, reducing claustrophobia while allowing full monitoring during treatment.
