Two chambers. One revolutionary platform. The same breathable, full-body cold — delivered by two brilliantly different technologies. Here is everything you need to know to choose yours.
Vacuactivus built its reputation on refusing to accept cryotherapy as it had always been done. The CryoStar Antarctica and the Antarctica Electric are the proof. Both chambers share the same foundational design philosophy — full-body immersion, breathable air inside, no direct nitrogen exposure, and therapeutic cold that reaches every cold receptor in the human body. What separates them is the technology they use to get there, and those differences matter enormously depending on how, where, and how often you plan to use one.
This article gives you the complete picture: what unites these two chambers, what distinguishes them, why each one excels in its own context, and exactly how to use them for maximum results. By the end, you will know precisely which one belongs in your facility — or your home.

The Shared Foundation: What Both Chambers Do Differently
Before examining the differences, it is worth understanding what makes both the CryoStar Antarctica and the Antarctica Electric exceptional compared to traditional cryotherapy — because both share a set of innovations that put them in a different league from conventional nitrogen cryosaunas.
The Breakthrough They Share
Both the CryoStar Antarctica and the Antarctica Electric solve the same problem that has plagued cryotherapy for 25 years: how to deliver extreme cold to the entire body safely, comfortably, and without the dangers of direct nitrogen exposure. They simply solve it with different tools.

| Operating Costs | Low nitrogen consumption per session | Electricity only — lowest long-term cost |
| Installation | Nitrogen supply line required | Standard 220V / 110V outlet — plug and play |
| Maintenance | Minimal — no specialist service needed | Any HVAC technician can service |
| Breathable Air Inside | Yes — 100% nitrogen-free inside cabin | Yes — 100% nitrogen-free inside cabin |
| Full-Body Immersion | Yes — head and neck included | Yes — head and neck included |
| Operational Continuity | Requires nitrogen supply | Non-stop after pre-cool cycle, no refills |
| Eco Profile | Low nitrogen use; heat exchanger efficiency | Zero emissions; fully sustainable |
| Best Environment | High-volume clinics, sports facilities | Spas, wellness centres, home, locations without nitrogen supply |
Why Choose the CryoStar Antarctica?
The CryoStar Antarctica is the answer for operators and facilities who want the deepest possible therapeutic temperatures — and who have access to nitrogen infrastructure. At up to −140°C, it delivers cold exposure that maximally activates the body’s protective and regenerative responses. For high-intensity athlete recovery programmes, clinical rehabilitation, and facilities treating clients with significant inflammation or chronic pain conditions, this temperature depth translates directly into more powerful, faster outcomes.
The heat exchanger system is a genuine engineering achievement: it harnesses nitrogen’s extraordinary ability to reach cryogenic temperatures, then strips out every safety risk associated with direct nitrogen exposure. Clients breathe clean air; nitrogen never enters the cabin; the system exhausts the gas safely outside. It is the best of both worlds — nitrogen power, electric-equivalent safety.
For facilities already equipped with nitrogen infrastructure, or those willing to establish a nitrogen supply, the CryoStar Antarctica represents the maximum expression of whole-body cryotherapy. It is the professional’s choice for results-first environments where temperature depth is a clinical priority.
Why Choose the Antarctica Electric?
The Antarctica Electric is the answer for everyone who does not want nitrogen in the equation at all — and that is an increasingly large and sophisticated group. Spas and luxury wellness centres, private home installations, facilities in jurisdictions with strict gas storage regulations, and operators who simply want the lowest possible operational overhead: for all of these, the Antarctica Electric is not a compromise. It is the superior choice.
Reaching −100°C, it achieves what research identifies as the optimal sub-zero exposure for maximum therapeutic efficiency. The compressor system is self-sufficient: standard electrical connection, plug-and-play operation, no nitrogen deliveries, no specialist handling, no logistical complexity. Once the pre-cool cycle completes, it can operate non-stop for hours — making it the highest-throughput option for busy facilities without nitrogen infrastructure.
The Antarctica Electric is also the most eco-conscious choice in the Vacuactivus range. Zero nitrogen emissions. Electricity consumption that can be sourced from renewables. A chamber that aligns with the environmental values that increasingly define premium wellness brands in the eyes of their clients.
How to Use Both Chambers: The Complete Session Protocol
The session protocol is identical for both chambers — another benefit of their shared platform. Operators who run both models in the same facility can train staff on a single workflow.
Health Benefits Delivered by Both Chambers
Because both chambers achieve full-body immersion with breathable air, they deliver the complete spectrum of whole-body cryotherapy benefits — benefits that partial-body nitrogen cryosaunas are structurally unable to match:
Accelerated athletic recovery: Rapid vasoconstriction followed by powerful vasodilation flushes metabolic waste from muscle tissue, slashing delayed-onset soreness and enabling athletes to train at higher frequency and intensity.
Systemic anti-inflammation: The body’s anti-inflammatory cascade activates across all tissue simultaneously — delivering measurable relief for joint pain, arthritis, post-surgical swelling, and chronic inflammatory conditions.
Skin rejuvenation and anti-ageing: Cold shock stimulates collagen and elastin production. Improved lymphatic drainage reduces cellulite. Enhanced circulation delivers oxygen and nutrients to skin cells — producing visibly firmer, more radiant skin with regular sessions.
Mood elevation and mental performance: Each session triggers a surge of endorphins, norepinephrine, and serotonin. Clients describe the post-session state as uniquely sharp, calm, and energised — with cumulative improvements in mood disorders, anxiety, and sleep quality over sustained programmes.
Cellular energy and immune activation: Full-body cold exposure stimulates mitochondrial energy production at the cellular level and activates white blood cell response — measurably strengthening immune function over a course of regular sessions.
Which Chamber Is Right for You?
Choose CryoStar Antarctica if…
You operate a high-volume sports recovery or athletic performance facility
Your clients include professional athletes or those recovering from serious injuries
Temperature depth is a clinical priority and you need maximum cold
You have nitrogen infrastructure already in place or can establish it easily
You are operating a rehabilitation clinic or chiropractic facility
Choose Antarctica Electric if…
You want the simplest possible installation — plug in and run
You operate a spa, luxury wellness centre, or premium fitness studio
You are installing in a private home or location without nitrogen supply
Eco-credentials and sustainability matter to your brand and clients
You want the lowest long-term operational costs with no consumables
The Verdict: Two Perfect Answers to Different Questions
The CryoStar Antarctica and the Antarctica Electric are not competing products — they are complementary ones. Each is the optimal answer to a specific set of operational requirements, facility environments, and client profiles. The question is not which is better; the question is which is better for you.
Maximum Cold. Maximum Results.
For facilities where temperature depth is a clinical priority and nitrogen infrastructure is available. The deepest therapeutic cold on the market, delivered without a single molecule of nitrogen reaching the client.
Zero Nitrogen. Total Freedom.
For operators who want the simplest, most sustainable, most operationally independent whole-body cryotherapy on the market. Plug in, power up, and deliver world-class results — no nitrogen required, ever.
What neither chamber compromises on is the thing that matters most: the therapeutic power of true whole-body cryotherapy. Every cold receptor engaged. Every session breathable. Every client treated to the full physiological cascade that partial-body cryosaunas have never been able to deliver. That is the CryoStar Antarctica platform — and in that respect, both chambers are simply outstanding.
