Yes, 150 PSI no bueno! I am sure a "." was left out. I spoke to a distiller with a HOGA in the Scotland who mentioned pressure testing the coil to 5 Bar and was running at 2. He did not use agitation so needed the higher temperature differential offered by higher pressure steam. Without doing the engineering my guess is that the better heat transfer coefficient of an agitated solution would make up for the difference in temperature and 1 bar (15 PSI Gauge) would finish a run in the times Chris stated.
