hi, is the Cooling Only model same in cooling than Immersion Pro? I don't need heating but very good cooling.
not sure if "cooling only" version is still available.Immersion Pro cost more (with bucket/carboy jacket - 299usd) as compared to Cooling only (with bucket/carboy jacket - 249usd)..and the answer is how the cooling is being transferred to rod is more likely the same..
Check this link.
Cooling only is still available and it utilizes identical chips as the Pro, so cooling performance is also identical. The Pro adds the ability to heat which is all in the circuitry of the control board.
