    Obviously you have never seen it ,, Low Temp racks this is common. It may not wash all compressors out.

    no i have not seen it

    i have seen many freezer circuits where the evap is a block of ice, to the point where the ice has crushed the copper tubes

    my experience is when using a constant superheat valve, ie
    TEV, the valve closes down to its min point or fully closes, ie the bulb pressure is insufficient to over come evap and spring pressure

    My mistake , sorry ,,,, I am confusing you & the original poster.
    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.
