The video below demonstrates how the feedstock for varnish deposits, oxidation by-products, that have precipitated out of solution are dissolved back into solution (soluble) when the oil temperature is increased. An opposite phenomenon occurs when peaking turbines go off-line and lube oil cools causing soluble contamination to precipitate out of solution resulting in varnish deposit formation throughout hydraulic control systems. Only SVR (soluble varnish removal) technology can remove oxidation by-products while still in solution to prevent precipitation and deposit formation in low flow and cool zones (servo valves). SVR is the proven solution to lube oil varnish!
