    I know 410 is the main alternative to 22 but does anyone know if the manufactures are working on any other refrigerents?

    Thre are a number of zeotropes available like Nu22B and a few other I can't remember the names of.

    I'm sure there will be a flood of pretender blends hitting the market once the supply of 22 gets tighter.

    I'm going to use only the original as long as there are R22 systems around.

    Equipment manufacturers have no plans to use anything other then Puron/R410a,as far as I have heard.

    Check out http://www.410a.com

    Nu22

    Watch out... its rumored that Nu22 will lose around 7-8% of the system capacity.

    NU-22 had a 5-15% capacity loss. I haven't heard what the NU-22B figures are. I sold one of their big shots a system for his house. He told me it is now running NU-22B and doing just fine. It is sized right on the money with nothing to spare so he must not have much loss with it.

    NU22B is supposed to be an improvement over the previous A blend ICOR sold. Capacity it SUPPOSED to be up considerably and they are touting it as a drop in replacement for R22.
    Yadda Yadda.

    Bring back CFCs and fuc* the guys with calloused inner arms.

    410A is closest thing to an azeotrope we are going to see from the chemical companies while in the mean time third world and a lot of Eastern European countries aren't even observing Montreal and Kyoto.

    R407c is a replacement to R22, except for an oil change. temp/press are very close. It is widely used in Europe.
