    TXV inlet Screen Stopped Up--30 OVE -TXV

    I have attached a Photo:
    This is a TXV-Sporlan-OVE 30 Ton--out of a Liquid Chiller--The Old Liquid Drier was a Sporlan 307---The Felt looking Debris--Would it be Possible for part of the Old Drier to have come Loose or could have some Foreign Material made it through the Drier---Anyone Experience this in the Past??
    Thank You.

    Maybe the last guy put too much heat to the filter/drier when brazing it in place. I've seen that happen. No nitrogen when brazing...
    "...refresh my memory. When did I start caring about this stuff...?"

    Seen everything from rubber plugs that were not removed to dead birds. Moisture and POE oil can create some nasty crap too. One of the reasons why you should look thru a pc of pipe before its installed (even if you just removed the caps from it.)

    I can't tell whats in there from the pic. I have had bi flow driers in YORK 6 ton heat pumps come apart in two different units. The stainless that holds the dessicant came apart into slivers and packed themselves into the indoor coil orifice. They were factory installed and were both Parker driers. However, this was years ago.

    I have also seen replaceable cores come apart in supermarket rack systems. So yes, it is entirely possible for driers to come apart for one reason or another.
