#2 is the idea I am leaning towards. I have room to mount an air cooled
BD50 directly below the box with plenty of ventilation.

Couple of things still have me stalled. I would like to use .192" ID
stainless tube which should stand up better to bumps with cans and
corrosion but the thermal conductivity is a lot lower than copper. I
could compensate by going to .335" ID but that might slow down the
refrigerant to much to push the oil through. Think I will stick with
.192" and adjust the expansion valve and compressor speed.

Glenn,

Another alternative could be a large stainless tube or box filled with
PEG/potable antifreeze, and containing the spiral of copper tube
inside. Depends the thermal conductivity of the PEG though. If a
stainless box is used this could have an aluminium finned surface to
improve thermal conductivity.

cheers,
Pete.
