How It Works
How To Use

Would you like to precisely control fermentation temperatures to eliminate off-flavors in your homebrew? Do you have limited space? Are you looking for an economical way to control your fermentation temperatures that still provides precise control?

The Temperature Control Loop can be used to control fermentation temperatures in individual carboys, buckets, conicals, or any other type of vessel. Ferment at ale or lager temperatures as low as 30 degrees F below ambient. System can be duplicated to ferment multiple batches at different temperatures simultaneously.

304 Stainless Steel is approximately 22 inches in length. Loop length can be adjusted for your application
Tubing is ¼” silicone
The rubber stopper is 100% silicone rubber and can be ordered in different sizes to fit your fermenter
The optional thermowell is 304 Stainless Steel and is 16 inches in length. This is the most accurate way to measure temperature.

The Ball and Keg Temperature Control Loop and rubber stopper is inserted into a filled fermentation vessel. A submersible pump (customer supplied) is used to pump ice cold water through the cooling loop. The pump can be plugged into a simple controller like an Inkbird (customer supplied) to precisely control fermentation temperature.

What you will need:

Temperature Control Loop from Ball and Keg
Controller with temperature probe. Inkbird, ITC, etc. (customer supplied)
Reservoir for ice jugs with a quart or two of water capacity (customer supplied)
Small fountain pump with 1/4" outlet and 60-100 gallon per hour capacity (customer supplied)

Other Notes

The silicone stopper will seal better if the surfaces are dry.
Insulate fermenter and reservoir to minimize ice usage.
If the thermowell is not being used, tape and insulate the temperature probe to your fermenter for accurate measurement.
