well a little weekend update.i got the cooling unit up and running.am running now and testing for leaks.i hope to get my load bench finished so i can start loading and testing the unit under stress.i used some r12 just to give it a fill and test with.my chiller tank seams to be doing good.i checked it and seams to be flowing real well at -27c with no signs of thickening up.evap temp was running well under -40c .not too bad just breaking it in.
