My most recently installed brite tank (BT0 in the diagram below) refuses to pull down past 38F. I've had problems with it since it was first installed in January 2020, and have had my installer back here a dozen times, but things have not gotten any better. Here's where I'm at and the things I've tried:
All other tanks pull down to 33F without issue. FV0 and FV4 are 15bbl, all other tanks are 7bbl.
I have an analog temp gauge installed in BT0, in addition to the thermowell with an RTD going back to the Brewmation panel. They agree.
When I make the setpoint for BT0 33F, the system correctly calls for cooling. I hear the solenoid snap open.
Product gets to 38F and doesn't cool further. Solenoid stays open, since the setpoint is 33F.
Both the bottom and top fittings on the glycol jacket eventually ice over, which tells me glycol is flowing.
I disabled all of the other tanks for a day in case it was a capacity issue. No change.
I thought maybe it was ice on the inside of the jacket, so I let the product come back up to 50F and tried again, with the same result.
This week I took apart and flushed the solenoid valve, as well as completely flushed the jacket in both directions with water. Everything is flowing well.
So I'm kind of at a loss on what to do next. It's an Apex tank, who recently went out of business, so I can't even ask them.
Could it be the way it was plumbed into the existing system?
