Unistat III

Test lab notes

We put four single-stage controllers to the test of powering our HERMS coil, managing fermentation temperature, and cooling our keezer, and Unistat 3 came out as our favorite. The build quality is solid, the indication lights were easy to read, and it was very easy to adjust from heat to cool. One extra feature it has that the others did not was the ability to have some variable power control—being able to set the keezer to 50% of power made sure that it didn’t freeze the entire unit before shutting it off. The system also has built-in controls for on/off at different temperature differentials to avoid quick power swings. The only wish-list function is dual-stage capability so it could trigger heating and cooling at the same time.
