To clarify...I did not mean to infer that York has been using mag bearings in the Navy, but that the Navy has been using mag bearings for years.
I'm third party to information, so it is filtering in. The 3 grand difference I previously referred to is operating cost/ year, not cost between the two technologies. The local is in S. Dakota and electrical engineer seems to think they have fairly reliable power, and clean. Site has emergency generators that when tested should not affect the chillers; except when loss of power occurs, projected at 6 times/ year. Question is sent to facilities to find out if that is realistic.
The mag chiller is the YMC^2, the other chiller proposed is a YK series.
