    Which txv

    Got a walkin freezer I'm finishing after another co started and was fired from the job.

    6x12

    Tecumseh cond AWA2464ZXDXC

    Heat craft evap LSF090BK

    They brazed a 1/4 ton TXV on there and only 3 fourths of coil turns frosty , after 4 hours only reached 45 degrees

    404A

    I think it needs a 1 ton valve ....am I right ?

    Ive never witnessed a TXV that was too big for a unit , but does anyone know if I did install that 1.5 ton valve could you crank it down far enough to actually make it work right?

    I dont know the maximum capable swings of adjustment..

    You could possibly choke it down if needed but at low load conditions it will give you issues. It will hunt all over the spectrum once down to temp.
