My uncle is in the COLD air business. He suggested to me he could build me a machine that could run cold refrigerant through the immerson chiller. My question have this been done before. How safe is it? He assured me that there is no leaking from his system and no ice or condensation would get into the wort. Any suggestion from the forum?

Seems sketchy, i could see it working but at what cost? Going from 15 minute chills to 10 minute chills?

as long as there are no leaks, and it's in a sealed refrigerant system, it could turn a 40 minute chill into 10 minutes. fuzze: note he is is fla, so that means hot ground water. i'm in texas.. i can relate

Youre likely to get a lot of condensation on the chiller coil that will drop into the beer

as long as the chiller is sanitized, shouldn't be a problem

There is no cost since he is building it from spare part. According to him copper or SS will work with his machine. Yes South floria water could be extremely hot at time.

The real issue here is superheat, you will not be able to cool the compressor. When your wort is near boil temp and you start your refrigeration system your suction (evap pressure) will blow the valves out of the compressor. If you are going to go ahead and try it video your adventure from at least 10' back.

I believe he will run it as a chilled water system otherwise....Youtube "Hey watch this" +1

Can you not use a traditional Immersion chiller to cool the wort to 110, discharging the water out of the system, then switch to the refrigerant?

I agree with grendle77, unless he builds a really, really big set up with a very large compressor and a huge radiator with a large fan blowing on it, you're likely not going to get very far. A typical refrigerator or air conditioner compressor is not designed to handle that much heat. Its a lot easier to cool air then it is to cool water and even the biggest industrial size air conditioners aren't designed to pull temps from 212 to 70 degrees (especially not that quickly)

Would love to see a video of someone trying though. Who knows, maybe we're wrong.
