Although this isn't the first time the Commercial Refrigeration Industry has gone through the process of phasing out its "status quo" refrigerant because of its environmental harmful properties, the industry has expressed an exasperated need for it to be the last.

In the past, Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) used to be the accepted refrigerants in the Commercial Refrigeration Industry. That is, until it was discovered that a hole was forming in the ozone layer as a result of the high ozone depleting potential from refrigerant emissions. Thus, the Montreal Protocol eliminated the problem by phasing out CFCs and HCFC refrigerants. Hydrofluorocarbons (HFC) refrigerants were then adopted because they had little to no ODP. However, in recent years it has been observed that HFCs are also extremely environmentally harmful as they possess very high Global Warming Potential (GWP).

Now, as the Commercial Refrigeration industry experiences increasing regulatory pressure to phase out HFC refrigerants and adopt natural refrigerant solutions, the industry wants a "future proof" solution that won't be phased out in the decades to come.

Developed with the support of ARPA-E, ITC's Stirling cooler uses only natural refrigerants and enables a "future proof" Stirling Solution for the Commercial Refrigeration Industry. By using a subcritical pressure CO2 secondary heat transfer loop, ITC's commercial refrigeration Stirling coolers are an all natural, low pressure, high efficiency refrigeration alternative for various commercial refrigeration applications including walk-in and reach-in freezers as well as low temperature supermarket refrigeration.
