Lager year round with this external overriding thermostat. It installs on a fridge or freezer to maintain optimal fermentation temperature—trying to lager in a fridge without an external overriding thermostat results in temperatures that are too cold for yeast or even in frozen beer. Plug the appliance of your choice into the thermostat, then plug the thermostat into a standard 120V outlet. An analog dial lets you set the setpoint temperature between 30 and 80°F, with 1 degree increments. The Johnson Control thermostat has a 3 1/2 degree differential, which means that the thermostat will shut the fridge or freezer off (stop cooling) at 3 1/2 deg below the setpoint and start the unit (resume cooling) once internal air temperature exceeds the setpoint—the effect of this fluctuation on the actual temperature of fermeting wort or beer will be insignificant.
Like the #7051, our Digital Temp Controller operates by overriding the internal thermostat in a refrigerator or freezer and gives the brewer greater control over the fermentation. Unlike the #7051, however, the digital controller has a digital display with adjustable differential. It can be used to heat or cool a fermentation environment - when hooked up to a refrigerator, it turns the compressor on when the ambient temperature rises above your programmed temperature; when hooked up to a heater, it activates when the temperature drops too low. A sensor probe monitors the temperature inside while the readout displays it in either Fahrenheit or Celsius. This is the ideal choice for lager brewers who include a diacetyl rest in their fermentations or for ales like altbier or Kolsch that require fermentation temperatures in the low end of the ale range.
Features a wide setpoint temperature range (-30° F to 220° F) and differential adjustment (1° F to 3° F). The temperature sensor is a 1.94 inch thermistor on an 8 foot cable.
The Electric Fermentation Heater can be attached to a fermenter to raise the temperature of fermenting beer or wine. The EFH can be attached to a glass, plastic, or steel fermenter using electrical tape and plugged into a 110V outlet; for optimum results, use in conjunction with an electrontic temperature controller.
This electric heating belt can help to maintain minimum fermenting temperatures in cold rooms or basements. Indispensible for making wine during Minnesota winters! Fits 5, 6, or 7.5 gallon plastic buckets; although the Brew Belt will also fit 3, 5, 6 and 6.5 gallon carboys, the manufacturer does not recommend using it with glass fermenters.
Use in conjuntion with the Johnson A419 Digital Temperature Controller (#40090) and the Electric Fermentation Heater (#40535) for complete control over fermenting temperatures in cool environments. Fits 3, 5, 6, or 6.5 gallon glass carboys.
These items allow the brewer to keep precise temperature control over fermentation during the cold months of the year. Includes a stopper thermowell, digital Johnson temp controller, and an Electric Fermentation Heater; you provide a compatible glass carboy, airlock, and a batch of beer or wine.
