The two products are designed to "clean and control."
Chevron has released their VARTECH Industrial System Cleaner, a non-solvent based varnish and sludge remover. The cleaner is found to cut and capture varnish and reduces the need for flushing at system cleanings.
Chevron has also debuted the newest version of their GST Advantage turbine oil. GST Advantage uses proprietary chemistry that improves oxidation stability, reduces oil degradation, and inhibits the precursors of varnish formation.
These two products are designed to complement one another in a two-step process that Chevron calls “the VARTECH solution.”
