I feel dumber then a box of rocks right now and I'm hoping somebody can help me. I am trying to locate a pressure temperature chart for group A-3 refrigerants (hydrocarbons ) Propane R-290, Ethane R-170 and Heptane R-?. I have been all over the normal sites with no luck. I had a nice laminated card that had them all, but somebody needed it more then me, I guess.-GEO Thank You

Can you recall the manufacturers of those stated ? You might start there or contact some ashrae design engineers. Also try scientific web sites , you'll be suprised at whats on them .
