To all listmembers,
Furthering the discussion about mains water cooling, we have
tried this method in the past but experienced corrosion problems
in the narrow bore copper tubing used to circulate water around
the mass specs between the diff pumps, causing local flooding.
If your water is metered, it is also an expensive option!
We've found that chilled recirculators can improve a diffusion
pump's performance compared with cooling by mains water which, in
summer, is at a relatively high ambient temperature making it less
efficient. Interested to hear if this experience is shared by others.
Thanks for all the suggestions and comments received to date.
