Handcraft Supplies Heat Belt can be used to maintain your fermentation temperature by adding a gentle heat to the outside of your fermentation vessel. Avoid cool fermentation temperatures which reduce your yeast's performance and increase the fermentation time. Simply tighten the belt around your fermenter and adjust the heat belt's position to adjust the temperature. Lowering the belt will increase the temperature and raising will decrease the temperature.

For more accurate temperature controller consider pairing this with the Rapt temperature controller or STC-1000 which will monitor temperature and switch the belt on and off as required.
