What this category is

Hard-Shell Chambers In One Paragraph

Hard-shell chambers use a rigid body - high-strength aluminium alloy, aerospace aluminium profile or stainless steel - with automatic pressure control and a door rather than a zipper. Oxygen Times builds five, covering single-person lying and sitting cabins, a 2-3 person modular room and the OHS Series shell with a 40 mm polycarbonate door.

The problem it solves

Why Buyers Choose This Format

A chamber that runs eight sessions a day is a piece of capital equipment, not a consumer product. Zippers, manual pressurisation and soft windows wear under that duty cycle. A rigid body with automatic pressure management, a mechanical door lock and dual electronic plus mechanical safety layers is designed for repeat commercial use and looks the part in a client-facing room.

Who buys in this category

  • Rehabilitation and wellness clinics running back-to-back client sessions
  • Sports performance centres with several athletes per day
  • Luxury hotels, resorts and residential projects where finish quality is the sale
  • Showrooms and demonstration centres that need a flagship unit

Where these chambers go

  • Clinics & Rehabilitation Centres
  • Home & Residential Wellness

Buyer questions

Hard-Shell Chambers Questions

Will a hard-shell chamber fit through a standard door?
The OHE20 is dimensioned so it can be moved through standard doorways and lifts. The OHD15 ships as CNC-machined modular aluminium sections and is assembled on site, which is the usual answer for larger rooms. Send your access dimensions before ordering and the factory will confirm the route.
What is the difference between the OHL Series and the OHS Series?
The OHL Series is a lie-flat aluminium cylinder, 230 cm long by 90 cm diameter, at 1.5 or 1.9 ATA. The OHS Series is an upright shell with a 40 mm polycarbonate door, electric seating and a 90 kPa maximum pressure, in 1-person or 2-person widths.
How much does a hard-shell chamber weigh?
The OHL chamber body is approximately 100 kg with a 60 kg All-in-One system. The OHS Series is approximately 330 kg for the 1-person version and 380 kg for the 2-person version. Floor loading should be checked before installation.
Can the interior colour and trim be changed?
Yes. Exterior and interior colour finishes, seating layout, control interface and electrical standard for the destination market are all OEM and ODM options.
