Real Temperature

The temperature that mattersisn’t on the display.

What determines the effect of a whole-body cryo application is not the coldest number, but the temperature your skin actually reaches – and how fast. In the research, that target sits at around 13.6 °C skin temperature.

What actually counts

Skin, not air

“Thermal shock” has no fixed threshold in cryotherapy. What matters is not the chamber’s air temperature alone, but how fast the skin cools and which skin temperature it reaches.

The literature frequently links a target skin temperature of roughly 13–15 °C with strong activation of the cold receptors. Below that range the sensation of cold does not keep rising without limit – so a colder air temperature is not automatically more effective.

The role of airflow

Why airflow matters

How fast the skin cools depends not only on temperature, but on air movement. A stronger airflow strips away the thin layer of warm air on the skin and increases heat extraction. A system with a more moderate temperature but high airflow can therefore achieve comparable – or even stronger – skin cooling than a system running much colder with little air movement.

In a whole-body cryo chamber with forced convection, skin temperature fell by an average of about 11 °C after three minutes – comparable to, or stronger than, some systems with substantially lower air temperatures. The authors attribute this to improved convection and the greater heat extraction driven by the airflow.

From research to device

We use the research – and develop devices from it.

POWERCAB STORM and POWERCAB ONE grew directly out of this understanding. Instead of chasing the lowest possible number, we engineered our systems around the interplay of temperature and airflow – around bringing the skin reliably and quickly into the range that matters. Electrically powered, without liquid nitrogen, developed in Germany. All systems are consistently designed for efficient energy use – precise, modern engineering instead of unnecessarily high consumption.

We state all three values. Others state one.

In this industry a chamber is often advertised with a single, especially low temperature – usually the theoretically lowest point in the system, not what reaches the skin. We consider that misleading. POWERCAB publishes windchill, evaporator and air temperature openly and separately. You see what you get.
