When the dramatic discovery of the ozone hole in 1986 forced the banning of chlorofluorocarbons (CFCs), the refrigeration industry switched to hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). HCFC¹s are also ozone depleting substances but less so than CFCs. Meanwhile, both HCFCs and HFCs are potent greenhouse gasses.

Greenfreeze uses hydrocarbons as the blowing agent for the insulation foam and for the refrigerant. Hydrocarbons are completely ozone friendly, and used in refrigeration have minimal global warming impact.Hydrocarbon technology is not dependent on patented foaming agents and refrigerants. The operating costs are lower, and the maintenance is easier than with HCFC or HFC technology.
