I think 400-450mm would be fine,if ya get ya end plates tigged 4mm inside ya ferrules,then have ya tubes tigged flush( if they protrude any from the end plates, then it will make welding more difficult) with the end plates,a good welder like the one I suggested should be able to seal the deal,brazeing can be problematic with so many tubes and plenty have struggled to get it to seal me included,I made one similar for my brother and had to have at least a half a dozen goes to get it right with brazeing ,I would fix one hole and create two more,flippin frustrating it was ,also I would get two 1/2inch npt weld on fittings tigged onto the main body of the condencer for ya cooling lines befor ya do the internals,anyhoo cheers hillzabilly :handgestures-thumbupleft:
