    Well, what are we desuperheating, here?

    Are we using liquid injection into the suction line to control discharge line temp?

    Are we desuperheating suction gas?

    I've worked on Margaux racks without a desuperheater and other racks with a desuperheater.

    It's not a two-stage rack, is it?

    I service a Margaux LT r22 rack with suction desuperheating. Is this what you have???

    The desuperheaters are operated by two circuits from a medium temp rack. The LT rack is a split header, therefore two desuperheaters. They are spec'ed and set to +11f SST.
