<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;mso-fareast-language:EN-US">They all work the same on our site. Initially though, we have put the air-cooled chillers of the Spectra and Talos outside (we were waiting for indoor space to be renovated).
During the last summer (min T 28 and max 42 deg C), the two chillers failed and had to be replaced. After the renovation we managed to bring the chillers inside one of the tech area, and since then I sleep peacefully. We literally cut a hole in the whole so
the hot air is extracted directly outside, this brings no need of extra AC in the chiller room.

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.<o:p></o:p></span></p>
