As localised cryotherapy becomes more common in physiotherapy, sports recovery, and rehabilitation, TruCryo believes more attention should be paid to how cooling is delivered. While many cryotherapy systems rely on liquid nitrogen, TruCryo uses compressed carbon dioxide (CO₂). The company believes this offers important practical advantages for clinics and practitioners.

Liquid nitrogen is stored at approximately -196°C and requires specialist cryogenic storage and handling. Because it is maintained at such an extremely low temperature, it naturally boils off during storage, so some nitrogen can be lost even when the equipment is not in use. The resulting nitrogen gas also expands considerably, making appropriate ventilation and storage procedures important. Compressed CO₂ provides a different approach. Stored in an approved pressurised cylinder, it remains available until required and does not suffer the continuous boil-off associated with liquid nitrogen. For clinics that use localised cryotherapy intermittently, this can provide a significant practical benefit.

TruCryo also believes the cryogen's temperature should not be confused with treatment performance. "The important question isn't simply how cold the gas is," says a Jason Peters, Engineer at TruCryo "What matters is the level of controlled cooling delivered to the treatment area, how repeatable that treatment is, and how easily the equipment can be incorporated into everyday clinical practice."

All compressed gas systems have safety considerations, and proper operating procedures and ventilation remain essential. However, avoiding the routine storage and handling of a -196°C cryogenic liquid can simplify the practical introduction of localised cryotherapy.

For TruCryo, the focus is therefore not on achieving the lowest headline temperature, but on providing controlled, practical and repeatable localised cooling supported by practitioner training, treatment guidance and technical support.
