Cooling Reliability
“Factory Tested” Isn’t the Problem.
Where the Cost Shows Up Is.** If you spend enough time around chiller plants, you start to notice something subtle. The system meets spec.The commissioning report is clean. And yet… something doesn’t feel right once the seasons change. Not broken. Just not behaving the same way. The Part No One Pushes Back On Most process…
Read MoreWhen the Chiller Trips, the MRI Clock Starts Ticking
A Director of Imaging for a major health system once told me: “We’ve got redundancy. If a chiller goes down, we’re covered.” They weren’t. Because in MRI and CT environments, a chiller failure isn’t just an HVAC event. It’s a time-sensitive stability problem. And most facilities don’t realize how little margin they actually have. The Reality Most…
Read MoreThe Pump Was “Perfectly Sized.”
Six Months Later the Cooling System Started Failing. If you spend enough time around mechanical rooms, patterns start to emerge. One of them is this: Cooling failures often start with a pump selection that looked perfectly reasonable on paper. The pump meets the design flow. The head calculation checks out. The specification is satisfied. And…
Read MoreWinter PID Malfunctions?
(Why “Smart” Chillers Go Dumb in Winter) Ever had a chiller that runs perfect all summer… then loses its mind the first cold night? 🥶 That’s not a weather issue.That’s PID loops arguing behind your back. And it’s one of the most expensive reliability failures I see in the field. 💡 The Setup Brand new air-cooled process…
Read MoreWhen Vendor Selection Goes Wrong
In the world of mission-critical design, one of the most overlooked—and most damaging—mistakes engineers make is choosing the wrong equipment vendor. This is especially true in the realm of process chillers under 100 tons, where engineering judgment, vendor capability, and real-world performance intersect in ways that can make or break reliability. Many mechanical engineers are experienced…
