Delivered and installed
We deliver, position, and commission the unit on site, connect the chiller and water care, and set it running. You do not touch a manual.
Whole-body cryotherapy, made with electricity
Kelvin chambers hold their set point session after session, from -110°C to -150°C, with no liquid nitrogen and nothing to refill. Two to three minute sessions, back to back, all day.

Every Kelvin is made to order and installed across the UK and Ireland by our engineers.
Kelvin 110
The entry to whole-body cryotherapy. Holds -110°C session after session and reaches its set point in about 40 minutes from cold, so sessions run back to back through the day. In Solo, Multi, and Max.

Kelvin 130
The performance standard. Holds -130°C, the temperature most performance rooms settle on, and reaches it in about 60 minutes from cold. Ready for two to three minute sessions all day. In Solo, Multi, and Max.

Inside every Kelvin
The cold is made electrically, held at a set point, and ready all day. No liquid nitrogen, no gas, and nothing to reorder.
Electric refrigeration
The cold is made by an electric refrigeration circuit, not liquid nitrogen. There is nothing to refill and nothing to reorder, and the only running input is power.1
Holds, all day
Once it reaches its set point the chamber holds, so two to three minute sessions run back to back. Each time the door opens the temperature rises 8 to 10°C, then recovers.
Solo, Multi, and Max
Solo for one person, Multi for one to three, and Max for four to six. Every temperature is available in all three sizes, so the room is sized to your throughput.
Two finishes
Opal White or Matte Black, the same chamber either way. Set the finish with your quote and it carries through to the build.
Commercial, not medical
Kelvin is a commercial recovery and wellness device and carries commercial CE marking. It is not a medical device, and we do not make medical claims for it.
Kelvin 110, 130, or 150
One chamber, three temperatures. Colder takes a little longer to reach set point, and every temperature comes in all three sizes.
| Specification | Kelvin 110 | Kelvin 130 | Kelvin 150 |
|---|---|---|---|
| Minimum temperature | -110°C | -130°C | -150°C |
| Time to set point | ~40 min | ~60 min | ~140 min |
| Session length | 2 to 3 min | 2 to 3 min | 2 to 3 min |
| Capacity | Solo to Max, 1 to 6 | Solo to Max, 1 to 6 | Solo to Max, 1 to 6 |
| Refrigeration | Electric, no nitrogen | Electric, no nitrogen | Electric, no nitrogen |
| Finishes | White, Black | White, Black | White, Black |
| Price | From £89,950 | From £94,750 | From £101,950 |
All prices are inc VAT and for the Solo size; Multi and Max are quoted per configuration. Most performance rooms choose the 130. If the room is a showpiece and wants the deepest cold, the 150 is the one.
What your site needs
A Kelvin is a fitted chamber with its refrigeration in a separate room. We survey the site and plan the layout with you before we build.
A plant room nearby
The main refrigeration unit sits in a separate room, 3 to 5 m from the cabin, air-cooled or water-cooled. We plan the run and the ventilation with you at survey.
Power
A dedicated 400 V three-phase supply for the refrigeration unit, and 220 V for the cabin. The exact draw is confirmed in writing before order.
Delivered in panels
Each chamber is made to order and shipped disassembled in panels, so it reaches rooms a built cabin could not. Our engineer assembles it on site.
Commissioned and handed over
We assemble, commission, and hand it over running, then walk you through the day-to-day. Delivery and commissioning are arranged when we quote.
What it is like to run
An electric machine you can run all day. No nitrogen deliveries, no gas, and a warranty that reflects a commercial build.
Power is the only input
Because the cold is made electrically, there is no liquid nitrogen or gas to reorder. The exact draw depends on the model, the size, and how often it runs, and we confirm it in writing before order.1
Warranty
One year on the whole machine and three years on the core refrigeration components. We support remotely with guidance and replacement parts, and send an engineer on site if one is needed.
Ready between sessions
It holds its set point through the day, recovering 8 to 10°C each time the door opens, so a full timetable of two to three minute sessions runs without waiting.
Why buy your Kelvin from PROTEC Recovery
Not a box on a pallet. Delivered, installed, and set running by the team behind it, then supported for the life of the unit.
Complete on arrival
Every unit ships complete, with its plant, controls, and water or air care. Nothing to source, nothing to bolt on later.
Finance and leasing
Spread the cost as a monthly payment or a lease, for a home or for a business, arranged before anything is built.
Supported across the UK and Ireland
One point of contact from order to install, with servicing, parts, and advice for the life of the unit.
Questions people ask before they buy
Is Kelvin a medical device?
No. Kelvin is a commercial recovery and wellness device and carries commercial CE marking. It is not a medical device, and we do not make medical claims for it.
Does it use liquid nitrogen?
No. The cold is made electrically, so there is no liquid nitrogen or gas to reorder. The only running input is power, and there is nothing to refill between sessions.
What does my site need to take one?
The main refrigeration unit sits in a separate room, 3 to 5 m from the cabin, air-cooled or water-cooled. It runs on a dedicated 400 V three-phase supply, and the cabin itself on 220 V. We survey the site and plan the layout with you before we build.
How long before it is cold, and can it run all day?
From a room-temperature start, the 110 reaches its set point in about 40 minutes, the 130 in about 60, and the 150 in about 140. After that it holds, so two to three minute sessions run back to back. Each time the door opens the temperature rises 8 to 10°C, then recovers.
How is it delivered and installed?
Each chamber is made to order and shipped disassembled in panels. Our engineer assembles and commissions it on site and hands it over running. Delivery and commissioning are arranged when we quote.
What support and warranty does it carry?
One year on the whole machine and three years on the core refrigeration components. We support remotely with guidance and replacement parts, and send an engineer on site if one is needed.
For home, or for business
The same chambers, specified two ways. Tell us where it is going and we survey it, build it, and commission it.
A private chamber, at home
Whole-body cold in your own space, electric and ready every day, with no nitrogen to handle. We survey, build, and commission it, then walk you through it.
Request a Quote See It as a Monthly Cost ›A cryotherapy room that earns its floor
Electric chambers for clinics, gyms, and performance centres, sized Solo to Max and built to run all day. One point of contact takes you from survey to install, with finance and leasing on every build.
Plan a Suite Finance and Leasing ›One room, planned end to end
Pair whole-body cold with a plunge, a chamber, and light as a single fitted suite. Tell us the space and the throughput, and we lay it out before anything ships.
Start Planning See Cold Plunge ›- Temperatures, timings, and running inputs are nominal and depend on model, size, ambient conditions, and installation. Kelvin is positioned for recovery, performance, and wellness, carries commercial CE marking, and is not a medical device. Full specifications are provided per unit before order.
