No varnish - no trip

Turbine trips are as costly as they are frustrating - from the floor up to the CEOs office. That is why we developed the CJC® Varnish Removal Unit VRU more than 10 years ago. A small upgrade to your plant that reduces oil and varnish-related turbine trips and downtime.

CJC® Varnish Removal Unit VRU

A cost-efficient solution to a common problem. Instead of time-consuming and wasteful oil changes, our CJC® VRU continually removes varnish and cleanes your turbine’s lubricant, leading to increased oil lifetime. This comes with several benefits:​

  • 80% drop in oil-related turbine trips & downtime​
  • MPC of below 15 guaranteed​
  • 50% shorter oil service time during outage​
  • 75% reduced oil consumption


Don’t just take our word for it
