Hi Justin,
We started with air-cooled and there were issues with leaves clogging it up
as others have suggested. We had our own chiller for awhile, which worked
better, but there were still issues as the chiller itself was outside. Then
campus expanded their chilled water loop such that it would run right down
our drive way. This coincided with our installation of the helium recovery
system so now both cryoprobes and two compressors are all cooled by campus
chilled water (there is a heat exchanger in between so we have a closed loop).
We are much happier.

Hi Everyone,
We're in the planning stages of upgrading our aging AV1-800 to something more modern.
Currently we have a 1st gen cryoplatform with an air cooled compressor outside on a
balcony. Maintenance is a small pain with all the tree leaves, cotton, and dirt.
If you had the choice would you go with another air cooled compressor or water cooled?
We don't have chilled water in the lab yet but it's about 50 feet away in a service
closet so it wouldn't be too bad to bring it in. Thoughts?
