    Re: Compressors Iced up

    1)it is better you put one defrosting timer for all system when you are designing blast freezer .


    2) when you were not fully loaded running with 2 or 4 compressor only will effect your pull down times not any thing
    check you expansion valve and position of bulb and cover it to sense more actual temp in suction line
