  •  How to calculate the speed of IMP line?

    Speed of MF IMP line =
    No. of drying zones X 3.75 meter (length of each drying zone) X 1.2 meter/min speed for each drying zone

    Speed for PF IMP line =
    No. of drying zones X 3.75 meter (length of each drying zone) X 4.75 meter/min speed for each drying zone
