I have been working on a start up brewpub that has been a scrape by situation from the start but is slowly getting better bit by bit. The main problem that I am having right now is I need a chart that tells me the appropriate specific gravity of glycol concentrations in the chiller reservoir(the big chiller that chills my fermenters) and what temperatures they are good for. My chiller doesn't have the typical coils in the reservoir set up instead it has a coil that is inline out of the reservoir that is chilled by the compressor coil. It is wrapped in what appears to be just styrofoam and felt after that. I have had quite a few freeze ups and my boss is basically saying that I will destroy the chiller if I keep freezing it up and I keep telling him our glycol concentrations are too low and that is why it is freezing up(2.8 degrees plato in the reservoir). I know in the past it seems like the target specific was 1.060 to 1.080 but can't convince him to buy glycol and I am on the verge of being locked out of my chiller room because he says it is my fault. The chiller has never chilled my fermenters down any colder than 40 F and most recently does no better than 48 F. Also, knockout is problematic because my chiller runs a secondary process on my heat exchanger which isn't getting me down to the intial fermentation starting point that I need(55-58F...using Wyeast 1007 and trying to get cleaner, lagerlike ales). The other big kicker is the fact that I have no program logic controllers installed on my fermenters so someone has to manually open and close the jackets on the fermenters to control fermentation temperature. Does anyone have a link to a chart and or any reccomendations on how to get through to the owners of this place. I have waded through hell and remarkably managed to put out decent beers.
I appreciate any help anyone might be able to offer.
