I slightly over diluted my glycol solution (did not account for excess water leftover in pipes and jackets) and it is now sitting at ~25% v/v. I have used up my glycol but I do have excess diluted glycol so I was wondering if it is possible to somehow evaporate the water to concentrate the solution?

You may well still be OK at that strength, but it depend on the primary chiller temperature used to chill the glycol. 25% is ok down to about minus 10C.
If you need to make it more concentrated, I would simply accept the loss of that glycol, though you might be able to save it in a sealed drum and use it for future partial top ups - but you would need to check if this is OK with a reputable supplierdick
