Refrigerator and other apparatuses containing CFCs

Refrigerators have to be treated because they contain CFCs in the cool generator circuit and in the insulating foam around the body. In the cool circuit, the coolant is CFC R-12. In the insulating materials, the foam is expanded with CFC R-11.

CFCs are organochlorated compounds of great stability and low toxicity which, since approximately 1930, have had a great commercial success for multiple uses: coolants, foam expanders, propellors..... The large proportion of CFCs belong to two types: CFC R11 and CFC R12. These compounds, if they reach the stratosphere, along with the impact of the sun's ultraviolet rays, cause the destruction of the ozone layer.
