GHG R-406A INFO

Technical Information

Note: much of this information came about several years ago, before Adobe Acrobat (PDF) format was invented. These older documents were scanned in jpeg, gif, or are postscript files. This resulted in large files and/or poor image qualities (jpegs). With the advent of Adobe Acrobat (PDF) format, the documents may be stored on smaller files and be displayed much more clearly. Adobe Acrobat reader is available for free. Click the following icon to get a copy if you don't already have it. Some of these older documents are being rescanned and/or converted into PDF format and made available as well. The refrigerant which became known as R-406A (GHG Refrigerant-12 Substitute back then) was invented in August 1990.
