**Site Bite: Replacing the Coil in a Liebert® Condensing Unit**
Join Chris Wright, a Chicago-area Account Manager, as he heads out on-site to P&W Foundry for an urgent coil replacement job. The situation was hot—literally and figuratively. The Liebert® condensing unit was critical for producing time-sensitive parts for the U.S. Navy, so downtime wasn’t an option.
On the same day we received the call, we were already on our way to measure the existing coil. The unit was located on a production floor where every minute counted, so speed and precision were key. The original coil had to be replaced exactly as it was—matching the number of feeds, fins per inch, and piping connections to ensure seamless performance.
The coil itself was large but accessible, which made the measurement process straightforward. However, there were some unique design elements that required careful attention. The copper connections extended from the bottom of the headers, and we had to match those precisely for an easy field installation. The flanges were also non-standard, requiring additional bends to stabilize the coil on its four supporting pillars.
Using detailed sketches and notes, we customized the replacement coil to fit perfectly. The customer had a tight 5-day production schedule, and the new coil was installed quickly and smoothly. Within a week, everything was up and running again, and the customer was thrilled with the performance and ease of installation.
It's always rewarding to see a project come together so efficiently, especially when it's critical to a customer’s operations. This job was a great reminder of why we do what we do—delivering reliable solutions under pressure.
