To optimize your cooling, here are a few things to look at.
- Confirm the glycol chiller is cooling or not; does the chiller maintain it’s setpoint?
- The glycol chiller may be too cold, causing beer around it to freeze and not chilling the entire batch evenly. We suggest keeping the glycol chiller at ~29F or higher.
- Verify the glycol temp with a different probe or measuring device. The glycol chiller probe may be picking up a warmer temp than the reservoir is actually at.
- Confirm there is enough glycol/water to cover the readout probe adequality. If not, your chiller could be reading the air temperature.
- If only running a single fermenter, chiller could be getting cold spot in the reservoir due to lack of agitation. If so, try moving the glycol return line around to encourage better circulation
- Make sure the inlet and outlet tubing in your chiller are spaced apart to prevent the pump from sucking up the warmer coolant that has just returned
- Check your water to glycol ratio. We recommend a ratio of 50% glycol, 50% water.
- See the TC100product guide (link HERE) which explains temperature inversion. This guide is especially important when you near 40 degrees Fahrenheit.
