Nitrogen cabin or electrical cabin ?
We are the only ones in France to have both technologies: nitrogen and electric. These correspond above all to different needs, in terms of volume of activity and speed of implementation.
The first of the unavoidable rules: seek the best quality of thermal shock. This will be automatic in an electric chamber because the entry into the chamber will necessarily be done with a pre-cooling temperature of -110°.
(We deliberately leave out the -90° mono-chambers from our discourse because they are tools developed in a purely marketing approach and intended to produce a range effect. These mono-chambers are not in agreement with the consensus of BAD VOSLAU (2006) defining the therapeutic efficiency zone of whole body cryotherapy in a temperature range between -100 and -140°).
In the case of a nitrogen cabin, each treatment should only be performed with the assurance that, when the patient enters the cabin, it will have been pre-cooled to -110°, so that the patient will undergo a true thermal shock.
Unfortunately, some unscrupulous operators equipped with cabins, which are greedy in consumption, will favour a nitrogen saving approach to the detriment of the quality of the thermal shock and the quality of the sessions.
These operators tend to make candidates enter a cabin that has not been sufficiently cooled, or even without any pre-cooling.
