GHG R-406A/R-414A INFO

Technical Information

Note: much of this information came about several years ago,before Adobe Acrobat (PDF) format was invented. These olderdocuments 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 maybe stored on smaller files and be displayed much more clearly.Adobe Acrobat reader is available for free. Click the followingicon to get a copy if you don't already have it. Some of theseolder documents are being rescanned and/or converted into PDFformat and made available as well. The refrigerant which becameknown as R-406A (GHG Refrigerant-12 Substitute back then) wasinvented in August 1990.
