Buyers spend weeks comparing chamber specifications and weeks negotiating price, then discover on installation morning that the doorway is ninety centimetres too narrow. It happens more often than anyone in this industry admits. Site preparation is the least glamorous part of buying a hyperbaric oxygen chamber, and it is the part most likely to delay your first billable session.
This guide is written for the people who have to make the room work: clinic owners, wellness centre operators, spa managers, hospital procurement teams and distributors preparing a demonstration unit. It walks through every decision that has to be settled before a crate leaves the factory — room dimensions, floor load, electrical supply, oxygen strategy, ventilation, acoustic comfort, access route, fire safety, and finally delivery day and commissioning.
The commercial argument for doing this properly is straightforward. Every week the chamber sits uncrated in a corridor is a week of lost session revenue and a week of carrying cost on a paid-for asset. Furthermore, most installation delays are entirely predictable: they are discovered during the site survey, or they are discovered when the truck arrives. Only one of those two moments is cheap.
| Checklist stage | Typically owned by | Must be settled before |
|---|---|---|
| Room dimensions and ceiling height | Facility manager | Order confirmation |
| Floor load and floor finish | Structural engineer / landlord | Order confirmation |
| Dedicated electrical circuit | Licensed electrician | Chamber ships |
| Oxygen supply method | Clinical lead | Chamber ships |
| Ventilation and acoustic review | HVAC contractor | Chamber ships |
| Access route survey | Facilities + freight forwarder | Vessel booking |
| Fire safety and signage review | Local fire authority / insurer | Handover |
| Incoterm handover point | Importer + supplier | Contract signing |
| Acceptance test criteria | Buyer + supplier | Delivery day |
| Staff training schedule | Clinical lead | Delivery day |
1. Why Hyperbaric Chamber Site Preparation Belongs Before the Purchase Order
There is a persistent misconception that a mild hyperbaric chamber is a plug-and-play piece of wellness equipment, comparable to a massage table with an air compressor. A hard-shell, fully welded chamber operating at 1.1–1.7 atm is a pressure vessel with a life-support function. It draws meaningful electrical power, it changes the oxygen concentration in its immediate surroundings, it imposes a point load on your floor, and it is delivered as a rigid object that cannot be folded, rolled or tilted through a tight corner.
Treating site preparation as a post-purchase activity creates three specific failure modes. First, the schedule failure: specialist trades (electricians, HVAC, structural) have lead times measured in weeks, and they will not start until you give them a specification. Second, the cost failure: retrofitting a dedicated circuit or reinforcing a floor after the building is finished costs several times more than doing it during fit-out. Third, the compliance failure: your insurer or local authority may require documented evidence — electrical certificates, ventilation calculations, fire risk assessment — before the room can open.
The sequence that works is the reverse of the intuitive one. Confirm the room first, then choose the model that fits it, then sign. To illustrate, a buyer who has already verified a 2.4-metre ceiling, a single-phase supply upgrade path and a 1.2-metre clear doorway can take delivery of almost any unit in the range with confidence. A buyer who has verified none of those things is gambling regardless of which chamber they buy.
| Mindset | Consequence |
|---|---|
| “Pick the chamber, sort the room later” | Trades booked late, rework, delayed opening |
| “Sort the room, then pick the chamber that fits” | Predictable install date, clean commissioning |
| “Treat it like standard wellness equipment” | Insurer and fire authority pushback |
| “Budget only for the unit price” | Unfunded fit-out costs discovered mid-project |
2. Room Dimensions, Ceiling Height and Clearance Requirements
Start with the chamber footprint, then add clearance on every face. Clearance is not wasted space: it is operator access, patient transfer, emergency egress and service access to the pressure relief hardware. Skimping here makes routine tasks awkward and emergency tasks slow.
Because the range spans a compact personal unit through to a high-throughput commercial cabin, there is no single answer for every buyer. Use the table below as the planning framework and fill the chamber-specific figures from the technical datasheet issued with your quotation — do not guess them.
| Model | Configuration | Planning note |
|---|---|---|
| AURA One | Single-user home / personal | Smallest footprint; verify door swing and stair access |
| NEPTUNE Flow | Portable single-user | Favours mobile or multi-site operators |
| LUMINA One | Single-user aesthetics-led | Spa and beauty-cabin fit-out |
| TITAN Duo | Two-user clinical | Higher throughput; plan attendant circulation |
| POLARIS Duo | Two-user high-flow commercial | 1.75 atm class; heaviest utility load in the range |
| Dimension | What to measure | Why it matters |
|---|---|---|
| Ceiling height | Lowest point including lights and sprinklers | Vertical clearance for entry and service access |
| Footprint | Chamber base plus mattress/stretcher travel | Determines whether two units fit side by side |
| Rear clearance | Wall to rear service panel | Compressor and valve servicing |
| Side clearance | Wall to chamber side | Operator and emergency access |
| Front clearance | Door/opening to nearest obstruction | Patient transfer and assisted entry |
| Door swing | Full arc of the chamber door | Frequently overlooked; blocks corridors |
A practical room-sizing worksheet helps keep this honest. Measure the smallest room you are considering, subtract the clearances above, and check what is left. If it is negative, the decision has been made for you.
| Worksheet line | Your value | Source |
|---|---|---|
| Room length / width / height | [TO CONFIRM] | Site tape measure |
| Lowest overhead obstruction height | [TO CONFIRM] | Site survey |
| Chamber installed footprint (L × W) | [TO CONFIRM] | Model datasheet |
| Required clearance total | [TO CONFIRM] | Model datasheet |
| Remaining free floor area | Calculated | — |
| Number of units that fit | Calculated | — |
3. Floor Load, Vibration and Structural Checks Before Delivery
Structural questions get skipped because the chamber looks like furniture. It is not. A fully welded aviation-grade steel shell plus patients plus attendants concentrates a substantial load into a small contact area — and repeats it on the same strip of floor thousands of times a year.
Two checks are needed. Static load: can the slab carry the assembled unit at rest? Dynamic load: can it tolerate repeated, slightly asymmetric loading without deflection or cracking? Suspended timber floors, mezzanines and rooms over occupied space deserve particular scrutiny.
| Structural check | Applies especially to | Acceptable evidence |
|---|---|---|
| Slab thickness and reinforcement | Ground floors | Building drawings |
| Allowable imposed load (kN/m²) | All upper floors | Structural engineer report |
| Point load at each foot | All installations | Supplier foot-load data + engineer sign-off |
| Deflection under load | Timber / suspended floors | Engineer calculation |
| Vibration transmission | Rooms above occupied space | Site measurement |
| Levelling tolerance | All installations | Supplier installation manual |
Floor finish is the second half of the problem. You need a surface that is cleanable, non-slip, anti-static where your electrical code requires it, and resistant to your infection-control cleaning agents. Seamless vinyl and epoxy are common answers; carpet and rugs are not.
| Floor finish | Suitability consideration |
|---|---|
| Seamless welded vinyl | Easy to disinfect; confirm slip rating |
| Epoxy coating | Seamless and durable; confirm anti-static requirement with your electrician |
| Polished concrete | Durable; can be slippery when wet |
| Raised access floor | Check point load capacity before committing |
| Carpet / rugs | Generally unsuitable — hygiene and static |
4. Electrical Supply, Circuit Protection and Backup Power Requirements
Electrical preparation is the single most common cause of a failed first commissioning visit. The pattern is depressingly consistent: the room looks finished, the electrician has run a spur off a shared ring, and the chamber trips the breaker the moment the compressor comes up to load.
The fix is decided weeks earlier, during design. A chamber needs a dedicated circuit, correctly sized, correctly protected, terminated at an accessible isolator, and verified by a licensed electrician who issues a certificate your insurer will accept. Confirm the rated supply voltage and frequency for your destination country at quotation stage — the same model configured for a 230 V/50 Hz market is not the same machine as a 115 V/60 Hz build, and this is not something to resolve after the crate lands.
Voltage and frequency, plug or hard-wired termination, inrush current behaviour, and whether your local code requires residual-current protection with a specific trip characteristic are all questions for your electrician and your supplier together, in writing, before shipment. Do not leave them to installation day.
| Electrical item | Who confirms | Evidence required |
|---|---|---|
| Supply voltage and frequency for destination | Supplier + buyer at quotation | Order specification |
| Dedicated circuit rating | Licensed electrician | Electrical certificate |
| Isolator location and accessibility | Facilities | Photograph + drawing |
| Earth / ground integrity | Electrician | Test result |
| Residual current protection type | Electrician, to local code | Certificate |
| Cable route and containment | Electrician | As-built drawing |
| Out-of-hours isolation procedure | Facilities | Written SOP |
Backup power deserves a decision rather than a hope. A mid-session power loss is not merely an inconvenience — the patient is inside a sealed pressurized vessel and must be brought down safely. Consequently, your emergency procedure and your electrical design must agree with each other.
| Backup approach | What it protects | Trade-off |
|---|---|---|
| No backup | Nothing | Relies entirely on manual depressurisation procedure |
| UPS on control electronics | Controls and communications only | Low cost; compressor still stops |
| Standby generator (auto-start) | Full session continuity | Higher capital and maintenance cost |
| Manual depressurisation protocol | Patient egress regardless of option above | Mandatory in every case |
Every unit in the range is specified with triple pressure relief — mechanical, electromagnetic and manual — precisely so that depressurisation does not depend on mains power. Your staff must nonetheless be drilled on the manual procedure until it is muscle memory; that training belongs in the handover session covered in Section 9. Likewise, the integrated 4G emergency call function should be tested and its coverage verified in the actual room, because steel structures and basement locations degrade cellular reception.
5. Oxygen Supply Planning: Concentrators, Cylinders and Bulk Supply
Our chambers pressurise the cabin with air and deliver oxygen to the patient through a mask or hood. That architecture has direct consequences for your site: you are not building an oxygen-enriched room, but you are managing a concentrated oxygen source inside a room, which makes supply logistics, storage and ventilation three connected decisions rather than three separate ones.
Delivery concentration is model-dependent — AURA One is specified at 80% oxygen or higher at the delivery interface, while the remaining models in the range are specified at 90% or higher. Ask your supplier to confirm the figure applicable to the exact unit you are buying, since it governs both consumables sizing and the ventilation calculation in Section 6.
| Supply method | Best suited to | Operational implication |
|---|---|---|
| Oxygen concentrator | Single-site clinics, moderate session volume | No cylinder logistics; power becomes the constraint |
| High-pressure cylinders | Low volume, mobile or temporary setups | Recurring delivery, handling and storage burden |
| Bulk / liquid oxygen system | High-throughput facilities | Capital installation, specialist supplier contract |
| Piped medical gas from central plant | Hospitals and large facilities | Requires integration with existing plant |
Cylinder handling brings obligations that surprise first-time buyers: secure upright storage, separation from combustibles, a defined maximum quantity on site set by your fire authority, and documented staff training on manual handling.
| Decision factor | Question to settle in writing |
|---|---|
| Peak simultaneous users | How many masks/hoods in service at once? |
| Daily session count | Drives consumable or cylinder consumption rate |
| Delivery access for suppliers | Can a cylinder truck reach your loading point? |
| Maximum cylinder quantity permitted | Ask your local fire authority directly |
| Storage location | Ventilated, secure, upright, away from heat sources |
| Redundancy | What happens if a delivery is missed? |
Price the supply model forward rather than backward. A method that looks cheap per session can be expensive once delivery charges, cylinder rental, handling labour and the floor area consumed by storage are included — the same total-cost logic set out in our companion guide on hyperbaric chamber total cost of ownership.
| Cost line | Unit basis | Your figure |
|---|---|---|
| Consumables or cylinder content | Per session | [TO CONFIRM] |
| Delivery / rental charges | Per month | [TO CONFIRM] |
| Handling labour | Per month | [TO CONFIRM] |
| Storage floor area opportunity cost | Per month | [TO CONFIRM] |
| Service and filter replacement | Per year | [TO CONFIRM] |
6. Ventilation, Temperature Control and Acoustic Comfort
HVAC is where comfort, safety and session compliance meet. Three things are being managed simultaneously: heat rejected by the compressor package, any oxygen that escapes the delivery interface into room air, and the perceived noise environment for a patient lying still for an hour.
Ventilation should be designed as a documented air-change rate for the specific room volume rather than as a vague assurance that “the room feels airy”. Heat rejection is a real load — the compressor and associated electronics dump heat continuously during operation, and a sealed room with no extraction will drift upward through the working day.
Acoustics matter commercially as much as clinically. AURA One is specified at 50 dB or below, chosen deliberately for home and quiet-clinic environments; the dual-occupancy units have different profiles your supplier should state for your configuration. In practice, most perceived noise in an installed room comes from reflection and structure-borne vibration rather than from the unit itself.
| HVAC parameter | Design question | Owner |
|---|---|---|
| Room air-change rate | Does it meet your local code for this occupancy? | HVAC contractor |
| Compressor heat rejection | Where does the rejected heat go? | Supplier + HVAC |
| Supply air temperature range | Maintains patient comfort across sessions | HVAC contractor |
| Return air path | Avoids short-circuiting supply to return | HVAC contractor |
| Filtration grade | Matches your infection-control protocol | Clinical lead |
| Noise criteria at patient position | Measured, not assumed | Installer + supplier |
Noise mitigation is mostly a fit-out decision, and most of it is cheap if made before the walls close.
| Noise source | Mitigation |
|---|---|
| Structure-borne vibration | Anti-vibration mounts; verify with the floor structure |
| Compressor airborne noise | Acoustic enclosure or relocated plant position |
| Hard-surface reflection | Acoustic ceiling tiles, wall panels, soft furnishings |
| Duct-borne noise | Acoustic lining and flexible connections |
| Door and latch noise | Soft-close hardware; staff behaviour in SOP |
Finally, remember who is in the room. An anxious first-time patient reads every unfamiliar sound as a warning sign, so a room that sounds calm reduces early drop-off — among the most expensive outcomes for a new therapy programme. For spa-led environments, our mild HBOT guide for spas and beauty clinics covers the patient-experience side in depth.
| Model | Delivery oxygen concentration | Acoustic note |
|---|---|---|
| AURA One | ≥80% | Rated ≤50 dB; suited to quiet and home environments |
| NEPTUNE Flow | ≥90% | Confirm at quotation for your configuration |
| LUMINA One | ≥90% | Confirm at quotation for your configuration |
| TITAN Duo | ≥90% | Confirm at quotation for your configuration |
| POLARIS Duo | ≥90% | Confirm at quotation for your configuration |
7. Access Route, Doorway Width and Crating: Will It Fit Through the Door?
This is the section buyers remember too late. A rigid, fully welded steel shell does not compress, does not tilt usefully, and does not forgive a ninety-degree turn in a corridor that is ten centimetres too tight. Before the vessel is booked, walk the route from kerb to final room with a tape measure and a camera.
Measure every constraint in the chain: the road or loading bay the truck can actually use, the goods lift internal dimensions and its rated capacity, corridor widths at their narrowest point (not their widest), every doorway including the final room door, ceiling heights along the entire route including under sprinklers and light fittings, staircases and their turning geometry, and any threshold or level change.
Then compare those measurements against the crated dimensions in your quotation — crating adds meaningful width and height, and the crate is what actually has to pass through your doorway.
| Route checkpoint | Measure | Your value |
|---|---|---|
| Kerb / loading bay suitability | Truck class that can access | [TO CONFIRM] |
| Goods lift internal dimensions | Width × depth × height | [TO CONFIRM] |
| Goods lift rated capacity | kg | [TO CONFIRM] |
| Narrowest corridor width | mm | [TO CONFIRM] |
| Narrowest doorway width | mm | [TO CONFIRM] |
| Lowest overhead obstruction | mm | [TO CONFIRM] |
| Stair width and landing geometry | mm + turns | [TO CONFIRM] |
| Crated chamber dimensions | L × W × H | From quotation |
When the answer is “it will not fit”, there are still options — but each one costs money and lead time, and each is far easier to arrange before shipment than on delivery morning. In most cases this is also the point at which your Incoterm election starts to matter, since it determines who arranges and pays for the final-leg solution. Our import and shipping guide walks through FOB, CIF and DDP handover points in detail.
| Constraint discovered | Possible mitigation | Arrange before |
|---|---|---|
| Doorway too narrow | Temporary door frame removal | Vessel booking |
| Lift too small | Stair carry with specialist crew | Vessel booking |
| Corridor turn too tight | Alternative route or re-siting the room | Construction start |
| Ceiling too low on route | Remove light fittings / reroute services | Fit-out completion |
| No suitable loading bay | Smaller vehicle plus shuttle | Vessel booking |
| Weight exceeds floor limits | Structural reinforcement | Fit-out completion |
8. Fire Safety, Signage and Oxygen-Enriched Environment Controls
A hyperbaric installation concentrates oxygen at a delivery point inside a room. That single fact drives the fire safety design, and it is why fire officers take a close interest in these rooms even when the cabin itself is pressurised with air rather than oxygen.
Your obligations are local, and that is not a detail to gloss over. Building, fire and medical gas codes differ substantially between jurisdictions; in many markets the relevant reference — NFPA 99 in the United States, alongside national equivalents elsewhere — is applied by the authority having jurisdiction rather than by the equipment manufacturer. Confirm requirements in writing with your local fire authority and insurer before you fit out, and keep the answer on file.
As a manufacturer-side statement, our chambers are supplied to CE marking with an ISO 13485 certified quality management system. We do not claim FDA clearance, and any buyer operating in a market where additional national registration or facility licensing is required should verify current scope and documentation directly with us. Our certification guide explains what each mark does and does not cover.
| Control area | Typical requirement | Confirm with |
|---|---|---|
| Ignition source control | No sparking devices in the room | Local fire authority |
| Textiles and furnishings | Flame-retardant, oxygen-compatible | Insurer + supplier |
| Portable extinguishers | Type and siting per local code | Local fire authority |
| Smoke detection | Integrated with building system | Fire contractor |
| “No smoking / no ignition” signage | Posted at room entry | Insurer |
| Emergency egress | Unobstructed route, practised drill | Facilities |
Prohibited-item lists should be written down, printed, posted and enforced. Verbal rules degrade fast in a busy clinic.
| Prohibited or restricted | Reason |
|---|---|
| Smoking and naked flame | Obvious ignition risk |
| Petroleum-based creams and ointments | Oxygen-enriched fire behaviour |
| Synthetic fabrics that generate static | Static discharge ignition source |
| Non-approved electrical devices | Spark and heat sources |
| Aerosols and pressurised canisters | Combustion and rupture risk |
| Lighters and matches | Ignition source |
Emergency provisions should be verified physically, not just listed in a manual. Test the manual pressure release. Confirm every operator can reach and operate it. Confirm the 4G emergency call connects from that specific room with the door closed, after-hours, with nobody else on site.
| Provision | Verification action |
|---|---|
| Mechanical pressure relief | Witness operation during commissioning |
| Electromagnetic pressure relief | Witness operation during commissioning |
| Manual pressure relief | Every operator physically operates it during training |
| 4G emergency call | Actual test call from the room, door closed |
| Emergency egress route | Timed walk-through during staff drill |
| Written emergency SOP | Signed acknowledgement from every operator |
9. Delivery Day, Commissioning, Acceptance Testing and Staff Handover
In practice, this is what separates a smooth opening from a contested one. Everything before this point is preparation; what follows is verification. The discipline that makes it work is agreeing acceptance criteria in writing before delivery. A typical sequence runs across one to several days depending on model complexity.
| Sequence step | Who attends | Sign-off |
|---|---|---|
| Crate arrival and external damage inspection | Buyer, freight handler | Delivery note endorsement |
| Uncrating and positioning | Installation team, facilities | — |
| Levelling and securing | Installation team | Photograph |
| Electrical connection and earth test | Electrician | Electrical certificate |
| Oxygen interface connection | Installation team | — |
| Power-up and leak check | Installation team | Test sheet |
| Pressurisation cycle test | Installation team, buyer | Test sheet |
| Safety system function test | Installation team, buyer | Test sheet |
| Acoustic and comfort check | Buyer | Test sheet |
| Operator training session | All operators | Training register |
| Acceptance document signed | Buyer + supplier | Acceptance form |
Acceptance testing should be specific and measurable rather than general. Pressurisation across the working range, stated as roughly five to twenty-five minutes to reach treatment pressure, is one such parameter; so are pressure-hold behaviour over a defined interval, audible alarm function, emergency depressurisation time, interlock behaviour, and door sealing.
| Test item | Expected behaviour | Result |
|---|---|---|
| Pressurisation to working pressure | Within stated time band | [TO CONFIRM] |
| Pressure hold stability | Within stated tolerance over interval | [TO CONFIRM] |
| Triple pressure relief function | Each mode operates independently | Pass / Fail |
| Manual depressurisation | Completes within stated time | [TO CONFIRM] |
| Door interlock and sealing | Seals and interlocks correctly | Pass / Fail |
| Audible and visual alarms | Function audible at operator position | Pass / Fail |
| 4G emergency call connectivity | Connects from installed location | Pass / Fail |
| Emergency stop | Halts operation safely | Pass / Fail |
| Acoustic level at patient position | Within stated figure for model | [TO CONFIRM] |
| Operator interface and controls | All functions respond correctly | Pass / Fail |
Training is the deliverable buyers most often under-specify and later regret. Insist on a defined curriculum, named attendees and a signed register — the register is what demonstrates operator competence to an insurer. Where the 1.1–1.7 atm working range (POLARIS Duo specified up to 1.75 atm) and the absolute contraindication of untreated pneumothorax are concerned, screening protocols are not optional reading; they are the core of clinical governance.
| Training module | Attendees | Competence evidence |
|---|---|---|
| Theory of operation and indications | All operators | Written assessment |
| Contraindication screening incl. untreated pneumothorax | Clinical screening staff | Signed protocol acknowledgement |
| Pressurisation and depressurisation cycle practice | All operators | Observed practical |
| Oxygen delivery interface fitting and checks | All operators | Observed practical |
| Emergency drills incl. manual release | All operators | Drill record |
| Infection control and turnaround cleaning | All operators | SOP acknowledgement |
| Daily / weekly / periodic checks | Facilities lead | Maintenance log |
| Escalation to remote technical support | All operators | Contact card displayed |
Finally, confirm escalation. The range is backed by global after-sales service with remote technical support, so establish the contact route, the response expectation for your region, and the spare-parts ordering path before you need any of them, and post it inside the room rather than in an email nobody finds at 7pm. Anything unresolved can go to the support team with your site survey attached.
10. Conclusion: From Site Survey to First Paid Session
The thread through all ten stages is sequencing. Confirm the room before choosing the chamber; settle the electrical specification in writing before shipment; survey the route against crated dimensions before booking the vessel; agree acceptance criteria before delivery; train and record before opening. Each step is unremarkable. Skipping one is how a four-week project becomes a twelve-week one.
For distributors this checklist is also a sales asset. Sending a site survey form before quotation turns an awkward future conversation into a demonstration of competence and protects both parties from a failed installation. OEM and ODM partners should ask how the standard is documented for their market, since local derivations will differ.
Take one action today: complete the Section 2 dimensions table and the Section 7 access route table using tape-measure values. Those two tables surface almost every problem early enough to fix cheaply. Send them with your enquiry so the quotation you receive is configured for the room you actually have.
| Timing | Action | Owner |
|---|---|---|
| Week 0 | Complete room dimension and access route tables | Facilities |
| Week 0 | Circulate completed tables with enquiry | Buyer |
| Week 1 | Confirm voltage/frequency and dedicated circuit scope | Electrician |
| Week 1 | Fire authority and insurer requirements confirmed in writing | Buyer |
| Week 2 | Oxygen supply model selected and costed | Clinical lead |
| Week 2 | Incoterm handover point agreed | Importer |
| Week 3 | Order specification confirmed and signed | Buyer + supplier |
| Pre-shipment | HVAC, electrical and floor works completed and certified | Facilities |
| Pre-delivery | Acceptance criteria and training dates agreed | Both parties |
| Delivery week | Installation, commissioning, training, handover | Both parties |
The commercial logic is unambiguous. Thorough site preparation costs a few weeks of planning and a modest amount of professional fees. A failed installation costs delayed revenue, rework, strained relationships and — in the worst case — an unusable asset. Choose accordingly, and start with a tape measure.
