Laserpure 60

Hi group.
I'm in a bit of a fix that I hope one or more of you can suggest a solution.
I recently acquired an older cell sorter that has 2 water cooled lasers (Enterprise II &
305c Krypton) along with an air-cooled argon.

My problem is that I need to use closed loop cooling for them and Coherent just told me
that they quit making the Laserpure 60.  

Does anyone have an idea for me on how to acquire a closed-loop system for my new lasers?

Thanks,
Phil Marder
