    Stal screw compressor catalog



    Hi dear colleagues
    I am dealing with 2 sets of Stal Srm refrigeration screw packages S26A-25 and R55C-25C working with ammonia. These packages are planned to reconstruct and use for another plant. I need to know the cooling capacity of these packages which is inaccessible on the internet. I wonder if any one can give me some info on them. I need the cooling capacity on below conditions. where could I find the R5 and S26 series selection tables or cruves?

    Hi I2embo

    no table or curve
    from software
    R55 at 50Hz/2970rpm, 287m3/h swept volume. without co, cooling capacity is
    -40/+40C; 31,9kw / 40,9kw shaft power.
    -25/+40C; 77,2kw / 46,8 kw shaft power.

    S26 same conditions, 713 m3/h
    -40/+40C 92,5 kw / 105,4 kw shaft power
    -25/+25C; 207,2kw / 116,6 kw shaft power

    beware, R5 compressors are delicate!!
