Water and air problems, temperature fluctuations and oil degradation in plastic injection-molding and blow-molding machines, EHC systems of gas and steam turbines, and hydraulic presses can occur due to varnish. Varnish results in valve sticking, shorter fluid life, shorter filter life, reduced equipment performance and unscheduled downtime. The varnish removal system removes oxidation b-products and prevents varnish formation during the cool down, according to the company. Long-fiber cellulose and PP cartridges are designed to remove dissolved varnish from fluids. Benefits include reduced rate of additive consumption and reduced servo valve sticking. The filter does not add water or other byproducts to the system, operates at a range of oil temperatures, and is compatible with all mineral and phosphate ester fluids.
