Reply to "New Turbine Oil Foaming"

It is our experience at Isopur, that removal of varnish and submicron contaminants with BCA and Electrostatic purifiers does reduce foaming. Very clean oil generally, does not foam.

An oil analyst I know has shown correlation between varnish potential, air and water release values. He suspects these tests may be as good as the VPI tests at determining varnish potential.
