How a varnish problem starts

High operating temperatures in your system deplete protective additives in your oils and cause it to degrade over time. The results — oxidation by-products, contaminants and more — can start to precipitate out of the oil. When they do, these deposits attach themselves to equipment surfaces and build up over time, forming a coating of varnish that quickly begins to do its dirty work.

The real business impacts

Varnish buildup reduces a lubricant’s heat transfer properties and causes your system to run hotter and hotter. The consequences won’t just threaten your equipment — they’ll hit you on your bottom line.

  • De-rated equipment, unplanned shutdowns, inefficient operation
  • Increased maintenance labor, management and spending
  • Higher costs and lost profits for the business owner
