Thanks for your reply.
In order to check the warning of grompp after scaling up I ran grompp again without -maxwarn:
grompp -f minim.mdp -c system_inflated.gro -p topol.top -o em.tpr
WARNING 1 [file minim.mdp]:
The sum of the two largest charge group radii (3.840099) is larger than rlist (1.200000).
Do I need to change the minim.mdp settings? Visualizing the system doesn't show any odd result!
Would you mind helping me?

It will decrease steadily. Make sure your loop is calling the correct coordinate file each time. The energy-minimized output of the previous step is the input into the next iterations of shrinking, i.e.:
system_inflated.gro -> em_inflated.gro
em_inflated.gro -> system_shrink1.gro -> em_shrink1.gro
em_shrink1.gro -> system_shrink2.gro -> em_shrink2.gro
