    [QUOTE=k-fridge;10425412] I think we'll see it go away in a few years.

    Honeywell considers it long term on there Guide to Alternative Refrigerants.
    Along with R404a,R507,R422a,R422d,&R407c.
    I personally think it should be banned in small cap tube reach-in's.
    On the flipside those Artic Air Freezers can get down to -30*
    Also many domestics refrigerators run the low side in vaccum.

    How old is that equipment ? Got a serial # ?
    The serial number is JA0995. I think it means it was made in 95. The newer models use a TXV.
