When it comes to engineering, more is not always better.

Machine calls for cooled water between 15 and 20 degrees. Customer was feeding it 5. From their side that's a free win, colder water, faster cooling, no downside. The photo is the downside. Factory humidity plus that supply temp and you get this. Condensation dripping below. Fix isn't complicated. Just need to install an actuated valve. Getting the customer to believe colder isn't always better, that's the actual job.
