I work on a project and I need to power new chiller (MCA - 611A, MOCP -700A at 208V, 3ph) selected by mechanical engineer on the roof of a high rise building. There is existing Power Company Transformer on the roof but without sufficient capacity to handle the new chiller.
I spoke to Power Company and they will provide a new transformer for the chiller.
I have some questions: :-?
1. How and what is best way (reliable, cheapest) to power the new chiller?
2. I propose to require from mechanical engineer to reselect the new chiller at 480V, 3ph to reduce the inrush current.
3. I can provide a new VFD for the new chiller but life expectancy of VFD is only 5-6 years. (I have read that in the forum).
Thank you
