[3dem] [EXT] microscope installation

[Reinhard Rachel]

Water-cooled chiller. I would never choose / use an air-cooled chiller, again.
(Ok, I am out anyway, due to retirement…).
We even had been going through the phase of changing an air-cooled version into
a water-cooled system - upgrading it. We had hot summer days , no, even weeks
(in cold Germany), where the capacity of the air-cooled system was
insufficient. Resulting in the shut-down of chiller plus TEM (120 kV!), for two
weeks.

Hi,

We are installing a new high-end instrument here and the issue of whether to
use an air- or water-cooled chiller has arisen.  I've always been in favor of
water-cooled chillers and at least some of the places where I have worked did
not have the capacity to remove the excess heat that an air-cooled chiller
would generate.  For this install, we appear to have a choice.

Is there a general consensus about which is better?
