I’m starting the upgrade of the cooler of my conical fermenter.
I have sourced a surplus COOLIT freezone
…that was made by a Canadian company in the past in order to watercool PC (overclocked CPU)
The basic principle is still the same…air-water heat exchanger and the cool water is recirculated inside the conical fermenter via a stainless steal coil
The new exchanger is a very nice piece of engineering
…very compact, colplete with pump, peltier cells, reservoir, fan…and it comes with a controller board that can control the power applied to the 6 cells and the speed of fun/pump according to set point and current measured temperature. So I expect that once the worth has reached the target temp the power will be adjusted in order to compensate just the heat produced by fermentation and loss of the system
The unit can be controlled by software PC via USB but it can works also stand alone
…it is possible also to log temperature and power during the whole time !
I need this week and to adapt some fittings and mechanical details and then I’m ready to test
