Our expansion tank (glycol system for comfort cooling) runs at a positive pressure when the system is off and goes into a vaccuum when running, sometimes as much as 20 Hg. Is this normal.Seems like a pretty high vaccuum.
System: Three 540 ton chillers, two 260 ton chillers. supplying 6 main cooling fans and multiple small chilled water units in the ceiling.
