We're having difficulty getting our tanks below 39/40 deg F. Our glycol is returning to the resevoir at 29deg F, so I can't imagine that's the issue. We cool adequately otherwise- crashes go down about 1 deg F per hour, but flatten out in the mid 40's and struggle to go lower. Thinking it might be a flow issue I've restricted cooling to one or two tanks but the issue persists. We have some high ambient temperatures right now- double brew days, a heat wave and no cooling in the brewery have us in the mid 80's to low 90's ambient, but we've also added a few new 40 bbl fv's in the last few months and cooling has struggled since they were introduced as well. We're having a really hard time isolating the source of our issue- any ideas out there?
