Im not using one, but did some extensive research before pulling the trigger and ordering a non-heated and cooled more beer conical. The cooling system on these is a TEC (Thermo electric Cooling) system. on the more beer web site they say
it can get to and hold lager fermentation temperatures of 48-52 Fahrenheit all the way up to ambient temperatures of 80 Fahrenheit.
I know with the TEC wine fridge I have, it is limited to 55º, and if its over 80º in the room it can't get to that temp.
But if you are looking to start fermenting at 44ºF, and If you had a way to chill your wort down to 44º before it went in to the fermentor, you can start at 44 and let it rise to 48º.
I'm having a 25' immersion chiller that fits through the 3" TC port on the top made for my 15Gallon conical, and planing on running 27º glycol through the coils. Others have used this technique and it works well. You can use a small freezer chest as a glycol reservoir,and a place to store hops too, the other plus with this rout is you can afford to buy two 27gallon conicals!
