This easy to install unit is a necessity for using a freezer unit for home draft and for controlling temperatures for lager beer.
Two Uses!
This controller is used for running a freezer or refrigerator beer dispensing or fermentation temperatures. Freezers have more floor space and are more energy efficient. However; to ferment or dispense draft beer they will need to have a wider range of temperature. Refrigerators normally run too cold for ales and some stages of lagers. This solved both. Just plug it in and dial up the temperature you want.
Remember most refrigerators will not go lower than 35oF.
