I would highly recommend it be between the compressor and the tank.
My, possibly faulty, logic.
The air coming from the compressor is really hot. This would enhance the
differential temperature between the radiator and the cooling air would be at
it's largest point. It would seem to make the radiator work as efficiently as
possible. In my case, 175 psi two stage, the input is over 200f and the output
seems to be close to 100f. The fan is blowing 70f room air over a 200f+
radiator.
The air would now be cooler as it enters the tank and hopefully most of the
condensation that is going to take place would be in the tank. Great for
one-place-to-drain.
No matter what the air will also cool while it is in the tank. This is a good
thing for condensation but it also means that, if the radiator comes after the
tank, the radiator will see considerably lower incoming air temperatures. On my
compressor the air coming out of the tank is often room temperature and is
seldom more than 10 degrees above room temperature. Therefore a radiator after
the tank would not have a huge differential to work with. At best it would be
blowing 70f air over a 90f radiator. Plus there is now need to have a local
drain for the condensation it might produce.
My thought is between the compressor and the tank, a condensate filter\water
separator and additional filters after the tank and then drains below coupling
on the drops.
Just my thought,
Arvid
