McQuay Centrifugal Oil pressure
Hi,
We have WSC100 McQuay centrifugal chillers. Have noticed that the Net Oil pressure drops while the chiller has just been started and stabilises later. It is set to maintain 110 psid, don't understand why the pressure drops to 60 psid at start-up.
We have six of them and all six have the same issue. They sometimes trip on Low Oil Delta Pressure. McQuay says there is no problem, but what about the future. Is anyone out there facing the same problem.
McQuay. I don't understand why they need 110 psid, the YORK I used earlier required just 35 psid.Setrite
