    DuPont™ ISCEON® MO29 (R422D)

    DuPontTM ISCEON® MO29 (R422D) is an easy to use, non-ozone depleting HFC refrigerant blend of R125, R134a and R600a.

    ISCEON® MO29 is used to replace R22 in a wide variety of high, medium and low temperature refrigeration applications as well as air conditioning and water chiller systems.
    It has also been used in new equipment and selected ‘flooded' applications.

    ISCEON® MO29 is a close match to R22 in terms of capacity and efficiency in most systems, but with a significantly lower discharge temperature which may prolong life of the compressor.

    ISCEON® MO29 is compatible with traditional and new lubricants, providing easy, quick, cost effective retrofits and can be topped up during service without removing the entire refrigerant charge.

    As ISCEON® MO29 is a blend it should always be removed from the cylinder as a liquid when charging a system.
    If you really know how it works, you have an execellent chance of fixin' er up!

    Tomorrow is promised to no one...

    Thanks for the correction.Read somewhere else that it could be charged as a vapour(I will look for the site).The dupont site also says:"After retrofit, can be topped off during service without removing the entire refrigerant charge"
