Vartech Industrial System Cleaner (ISC; photo) provides turbine operators with a non-solvent-based solution for removing varnish and sludge in turbine-oil systems. Vartech ISC can be added directly to oil during operation to clean varnish and sludge before a scheduled oil change. Vartech’s advanced chemistry helps improve oxidation stability, reduce oil degradation and inhibit the precursors of vanish formation, all while demonstrating excellent seal compatibility. This system compatibility also reduces performance impact for the new oil when flushing is impractical, and it does not need to be used in conjunction with a varnish filtration system. — Chevron Lubricants, San Ramon, Calif.
