Hi Luke,
Don't let them push for integration. My university is working on getting a
helium system installed and they went that way to start with. It has caused
so many issues that we are now getting a chilled water loop installed. Better
to have a stand alone system so that it can keep running when the main water
chiller goes down (which ours does a couple times a semester here, sometimes
without warning).
You won't just be dealing with algae, but depending on what floor you are on,
you can deal with a lot of sediment from the pipes accumulating. Our He system
is being installed in the basement, which makes it the low point for the entire
building's plumbing and we've had constant issues with filter changes since it
was installed, to the point where we just took it off line until the chiller
could be installed.
Good luck to you,

Hi all,
I'm planning end-of-life transition for our chilled water recirculator which
services two helium compressor cold heads. The main unit sits in a hallwa
just outside the lab, and the building's design doesn't allow for putting
it anywhere else.
1) Any recommendations for vendor or chiller type? I'm also interested in
general quotes (feel free to message me privately with any insights on what
we might expect).
2) Some in my department are pushing for integrating into the chemistry
building's existing chilled water network. I've not heard of labs choosing
this approach, and my impression is endless complications from algae and other
sundry building issues. Anyone seen success with this? Or is it one of those
39-and-a-half-foot-pole topics?
Kind regards,
Luke
