Cold therapy works by subjecting the body to severely chilled air, liquids or surfaces, setting off a chain of physiological reactions — blood vessels constrict, endorphins are released and metabolism speeds up. Inside a nitrogen chamber that exposure means air cooled to between −100°C and −150°C, applied only briefly and typically for three to five minutes. The sudden temperature drop does the rest: inflammation eases, sore muscles recover faster, mood lifts and energy rises. That is why athletes, wellness centres and spas build cold therapy into their regular programmes.
A growing body of research points to genuine benefits from hyper-cooled air. What drives them is the abrupt shift in surroundings: as chilled air moves across the skin, the body answers with an immediate sense of refreshment. Many people leave a session feeling renewed, and since the treatment only takes a few minutes it is easy to keep up as a regular habit. Athletes use it between training days, wellness centres use it for recovery programmes, and spa guests value the crisp, energising finish to a treatment.
Step into a cryotherapy chamber and the cold arrives fast — about three minutes of extreme dry cold, settling on the skin’s surface like a sharp breeze and stopping there, never reaching deeper tissue. An ice bath asks much more of you: fifteen to thirty minutes submerged in cold water, which pulls core temperature down and leaves you stiff and uncomfortable. The dry cold of a chamber is easier to take and you can move on with your day straight after, which is why gyms and clinics prefer it for repeat sessions.
Sometimes described as sensory deprivation therapy, floatation is a relaxation practice built around effortless floating. The tank holds water saturated with Epsom salts and warmed to skin temperature, so muscles can let go completely while sound and light fade into the background. People use it to unwind, ease muscle and joint tension, sleep better and clear the head. Spas, wellness centres and home users all value how little effort it takes.
Our equipment is CE certified. Certificates covering the cryotherapy chamber, float tank, hyperbaric chamber and dry water massage bed product lines are issued by third-party testing bodies (ZRC and EU TEST) and are available on request — the documents we hold are published on our Certification page.
A float tank — also called a floatation pod or sensory deprivation tank — is a light-proof, sound-insulated enclosure holding a shallow pool of water saturated with Epsom salt. The high salt content makes floating effortless, so you rest on the surface without any effort. Our commercial Whalepod models are built for spa and wellness-centre use, with their own filtration and temperature control.
Three things do the work: Epsom salt density, water temperature and insulation. The salt concentration is high enough to keep your body afloat on the surface, the water is held around skin temperature (about 35°C) so the boundary between body and water fades, and the enclosure blocks out light and sound. Filtration and heating run on a dedicated system so every session starts clean and warm.
Most users come out feeling deeply rested. The weightless posture releases pressure from muscles and joints, the quiet environment quiets a busy mind, and the warmth encourages circulation. Regular floaters report better sleep, less tension and sharper focus in the days after a session.
Healthy adults looking for relaxation, recovery or stress relief are ideal candidates. Float centres, spas, hotels and sports recovery facilities all run float programmes for exactly this reason. Anyone with a medical condition, open wounds, or who is pregnant should check with their doctor before floating. We supply guidance notes with every unit for operators to share with guests.
Sixty minutes is the standard commercial session — long enough for the body to settle into the weightless state and for the mind to slow down. First-timers sometimes prefer forty-five minutes. Operators set their own session lengths; our control systems make it easy to adjust the timer for each guest.
Yes — commercial float tanks are designed around guest safety. The water is shallow (around 25–30 cm), the salt content makes sinking almost impossible, and you can open the door and step out at any time. Temperature and filtration are regulated automatically. We recommend operators post clear safety guidance and keep a staff member within call during sessions.
Float tanks are installed in spas, wellness centres, hotels, sports recovery clinics, physiotherapy practices and private homes. Commercial units are built for repeated daily use; our clients run them in high-traffic settings from boutique spas to hotel wellness suites.
Home use is possible with a portable cryotherapy unit, but most of our electric and nitrogen chambers are built for commercial settings — gyms, sports clubs, clinics and wellness centres — where they are shared across many users. If you are considering a home installation, tell us about your space and power supply and we will recommend the right model.
Whole-body cryotherapy is widely used in sports and wellness settings and is generally well tolerated. Sessions are short (three minutes) and dry, and the user can step out at any time. As with any treatment, people with certain medical conditions — uncontrolled hypertension, heart conditions, poor circulation or pregnancy — should consult a doctor before use. Operators should screen guests before each session.
Frequency depends on the goal: athletes in heavy training often use cryotherapy two to four times a week, while general wellness users are happy with one or two sessions a week. Since a session takes only three minutes, it is easy to fit into a regular routine. Our team can help you design a session schedule for your facility.
Nitrogen chambers cool the air to between −100°C and −150°C using liquid nitrogen, reaching deep cold fast and offering the coldest sessions. Electric chambers use a refrigeration cycle, deliver a more moderate temperature range (around −40°C to −60°C for many models), and run without consumables — lower running cost and no nitrogen handling. Nitrogen suits the coldest-demand users; electric suits gyms and clinics that want simple, predictable operation.
Every product line — cryotherapy chambers, float tanks, hyperbaric chambers, dry water massage beds — is covered by a manufacturer’s warranty. The exact period depends on the product and the terms agreed at purchase; ask us for the warranty document for your model before ordering.
We supply installation guidance with every unit, and our after-sales team can walk your installer through the process remotely. For larger projects we arrange on-site installation and operator training. Tell us about your site and we will confirm what support is included.
Contact us with a description of the problem and, if possible, a photo or video. Our after-sales team will troubleshoot with you remotely and, if needed, ship the spare part. We keep troubleshooting efficient so your downtime stays short — that is what our after-sales support is for.
