The ice bath in your backpack

Our CGX1 device is like an ice bath in your backpack’. Designed to overcome the critical performance and logistical issues with current treatment methods, CGX1 provides a complete solution for all instances of heat-related illness. Our patent-pending technology emulates ice water immersion with a fraction of the resources. A powerful coolant stored within compact canisters is injected into conductive pads placed on the patient to deliver instant cooling. CGX1 is designed to be used in the most remote and extreme environments, enabling life-saving cooling to be delivered in any scenario.

Why CGX1?

CGX1 is used by paramedics and other first responders to provide immediate core body cooling to people suffering from heat-related illness. By utilising proprietary technology, CGX1 acts as a life-saving device and helps ensure better patient outcomes.

Our technology is the first portable, immediate and effective pre-hospital core body cooling device.

CGX1 is comprised of a body-conforming pad that is cooled via a non-toxic, inert compressed coolant. The device design overcomes many issues ensuring that:

  • Powerful cooling proven to reduce core temperature to safe levels
  • No pre-preparation or special storage required
  • Easy to use with life-saving cooling able to be delivered within 2 minutes of diagnosis
  • Effective for at least 30 minutes
  • Man-portable at under 5kg
  • Allows for CPR to be provided whilst cooling is applied
  • Proprietary technology emulates cooling mechanism of ice water immersion

Rapid cooling in cases of Heatstroke protects the brain and other vital organs and is of greatest benefit when applied early in the treatment pathway. Time is of the essence when treating Heatstroke, rapid cooling is essential in promoting optimal patient outcomes.




Risk factors for heat illnesses among new soldiers include exercise intensity, environmental conditions, a high body mass index, and conducting initial entry training during hot and humid weather.

In 2021, there were 488 incidents of heatstroke and 1,864 cases of heat exhaustion among active component service members of the U.S.
Armed Forces (a rate of incidence of 0.37 and 1.40 cases per 1,000 person years respectively).



Construction workers are at risk of death, injuries, illness, and reduced productivity resulting from heat exposure on the job. Between 1992 and 2016 in the U.S. more than a third of all occupational deaths from heat exposure were in the construction industry [Dong et al. 2019]. It is possible that heat-related deaths were undercounted due to misclassification.

Studies show that construction workers are more than 13 times at risk of heat-related death than those in most industry sectors [Gubernot et al].


Heat injuries have become a considerable health risk for sport and exercise participants. Studies show that sport-related heat injuries constitute over 10% of all heat injuries.

While sports requiring elevated physical exertion are obvious candidates, heat illness is found also in some that are perceived to be more passive. In Victoria, Australia the two major culprits were golf (>13% of cases) and lawn bowls (>11%) [McMahon et al. 2020].
First Responder

First Responder

Heatstroke represents a unique medical challenge to the prehospital healthcare provider due to the time sensitive nature of treatment. When cooling is delayed, there is a significant increase in organ damage, morbidity, and mortality after 30 minutes, less than the average EMS transport and ED evaluation window.

Rapid recognition followed by immediate effective cooling is key to achieving a 100% recovery rate.
Fire Service

Fire Service

Firefighters tolerate a high level of metabolically challenging demands which require a mix of sustained aerobic and maximal anaerobic capabilities, depending on the dynamics of the emergency. When combined with extrinsic factors of high ambient temperature, flame radiant heat and heavy protective clothing with self-contained breathing apparatus, rises in core body temperatures are inevitable. If their normal thermoregulatory responses are overcome, immediate cooling is vital.

Seasonal high temperatures are associated with heat illness, which can range from minor (heat cramps, edema, prickly heat, and syncope) to
serious conditions (heat exhaustion or heatstroke). Many factors play a role in the outcome of heat illness, including old age, chronic disease, overcrowding, physical exertion, lack of acclimatisation and dehydration. A lack of proper treatment exacerbates the condition to organ failure, convulsions, coma and increasing intracranial pressure.
Heavy Industry

Heavy Industry

Heat­-related deaths often occur in occupations in which workers are performing tasks in hot environments whilst necessarily wearing personal protective equipment, causing them to build metabolic heat faster than their bodies can release.

Guidance for prevention of heat illness exists but, when it is ignored, circumvented or fails in its aims, immediate effective treatment is crucial.


Occupational heat stress is a recognised health and safety hazard in mines. The consequences of high occupational heat loads can be expressed in terms of impaired work capacity, errors of judgment with obvious implications for safety, and the occurrence of heat disorders, especially heatstroke which is often fatal.

Rapid cooling prevents mortality and reduces long term debilitation, allowing return to work sooner.
