Tru°Cryo Limited are a UK based manufacturer of the Kaasen family of localised cryotherapy devices. The Kaasen is a dry, pressurised vapour therapy which provides rapid cooling of the skin and underlying soft tissues. Applied topically, the Kaasen stimulates an optimal, local response from the body which aids in recovery by reducing pain and inflammation. Kaasen is unique in offering two forms of cryotherapy, cold massagers and nozzles which spray carbon dioxide (CO₂) under pressure, cooling the body to below 4°C. With the many nozzles available, the pressure of the spray is variable - from a gentle 6 m/s up to a firm 34 m/s.
