    R-414B (Hot Shot)

    I was talking with Copeland today and they said that they do not recommend Hot Shot for R-12 replacement because of it flammability, they do recommend R-409A, I checked the MSDS of each Refrigerant and the two of them have a rating of 1.
    Does anyone had any problem with Hot Shot in the past?
    I used it several times and never have any problems, but today's conversation with this copeland's technician raised a concern in my mind.

    HotShot (R414A) is an HCFC blend which contains 1.5% R600 (Isobutane) to improve oil return...but I don't believe it's flammable in normal use and application.

    It's not on Copeland's approved list of refrigerants, so it's difficult to say whether you were getting the company line on this or just personal opinion.

    I put it in a lot of systems. I guess maybe I'll start double checking that I don't have any gas trapped any where before I get the torch out.

    it is much simpler to use a refrigerant that is "accepted" by a manufacturer. I don't think any manufacturer has accepted hot shot (many change that "O" to an "i". Rcall the threats HotShot made to us ".. gonna sue"

    could be a similar situation as 410a

    Remember this thread, MSDS said not flammable but appearently under certain circumstances it can be very dangerous.

    I used Hot Shot for years with no problems. I think you'll find out that 409a will cut your capacity noticeably. We used it one time and ended up pulling it back out and installing Hot Shot. Never had a problem with the flammability either. It's hard to find a replacement that will do the same job as the good old R12. Now we are facing the same issue with R22 !!!!! Instead of one refrigerant, we'll now need about 4 different ones!!
    If you can't fix it with a hammer, you've got an electrical problem.

    I've used Rs-24 in school on small systems, was very comparable to 12. Never used it on any big systems though

    Times Two.

    With older systems I'm not worried about what the manufacturer says. I want the thing to work and have a satisified customer!

    RS-24 (R426A) is an HFC long term replacement refrigerant for R12, whereas HotShot is an HCFC and is scheduled for phaseout along with R22, R401A, R409A, etc.

    http://www.refsols.com/RS-24_p1.html

    I haven't even seen any R426A, let alone tried it....but it's very similar to DuPont's Isceon MO49 Plus (R437A) which I have tried and like very much.

    http://www2.dupont.com/Refrigerants/..._MO49Plus.html

    Each is a slightly different blend of mostly R134A, then R125, R600 and R601A.

    I had to eat a $1500 unit from Tecumseh 5 years ago because they do not reconize Hot-Shot
