I've got a 10 HP unit that seems to be unable to keep up with the Alabama heat. However, based on the loading calcs it should be able to handle it.
Background: 2 30 bbl fermenters and a 30 bbl brite. Currently fully loaded.
I used the unit in the 2nd stage of the heat exchanger to drop beer temp, resulting in the temp of the reservoir (3 bbl) running up to about 28 C. Since then I've been struggling to drop the temp back down without the thermal overloads on the unit tripping. We burnt up one of the thermal overloads trying to drop it down. They are both replaced now and the unit still won't drop the reservoir down to the set point unless I'm actively misting the coils of the unit and that's not running the loop that is intended to cool off the beer.
Anyone got any ideas on what I need to work on? One thing I"m worried about is that Glycol Water Mix actually affects the performance of the unit rather than just the freeze point of the liquid. In other words, I'm not worried about freezing it but should I be worried about the chilling being less effective.
My other idea is just to change out the circuitry since it seems to be undersized.
