The opening is roughly 1.75″, which is plenty for Immersion’s 1.5″ diameter rod. A 0.5″ hole is drilled in the neck and a special sleeved grommet is used to allow for a sanitary air release.

DIY

Most 3 to 8 gallon fermenters, both conical and bucket shaped, can fit BrewJacket Immersion. If you have a model that you would like to use with Immersion, follow the following guidelines to alter:

 

Rod Hole Size 1.75″
Airlock Hole Size 0.5″

Incompatible Fermenters

Small Neck Glass Carboys Immersion requires a 1.75″ hole (#10 stopper size or larger) to fit properly. Traditional glass carboys can only accept #6.5 stoppers. Immersion’s rod simply does not fit.
10 Gallon Fermenters and Larger Immersion is tuned to ferment 5 gallon batch sizes. When the batch size is increased, it’s performance declines, so it is not recommended to use fermenters larger than 5 gallons.
