We are seeing our glycol pressure on the supply header (2" copper header with 3/4" and 1" PEX drops) coming into the building going up and down sporadically from 0 PSI to 20 or 25 PSI, with or without a load. We are just firing up our brewery and are fortunate to have more chiller than we need (always planning for the next tanks...) and well-insulated cellar tanks, so there hasn't been a huge demand on our chiller. Our glycol loop installers used what they called circuit setters in the bypass locations to make sure we don't deadhead the pump. We have also been trying to keep pressure down by throttling the ball valve of the supply header when it enters the building. The 550 gallon reservoir is more than 80% full and the percentage glycol is at 35%, verified by a calibrated glycol refractometer. Please let us know if you have an insight into this situation, or if there is more info I can provide to help resolve it.
Cheers!
