The Problem:
Varnish is sabotaging your equipment—and your uptime.
If you’re seeing sticky valves, overheating components, or unexplained trips in your turbines or hydraulic systems, varnish is the likely culprit. And the worst part? You don’t need sludge to have a problem. Varnish starts forming invisibly, long before you can see it. Left unchecked, it will cause failure.
Most “Fixes” Just Push the Problem Downstream.
Chemical flushes are often prescribed as the go-to varnish solution. While they can work, here’s the truth:
- They require full shutdowns
- They’re labor-intensive and intrusive
- Sensitive components must be “jumped out” to protect them
- And within months… varnish comes back
Chemical flushing is a reset button—not a solution.
The Real Solution:
Constant Remediation. Continuous Control.
At Larger Hydraulic Services, we help our customers avoid downtime with the same strategy trusted by the global power generation industry:
Depth Filtration Systems from CJC – HDU & VRU Series
These systems don’t just trap varnish—they actively remove and prevent it, using a combination of adsorption and absorption to control varnish at its source.
🎯 Here’s What We Guarantee:
- ✅ MPC values of 5 or lower
- ✅ UC values of 2 or lower
- ✅ ISO 4406 codes of 16/14/11 or cleaner
- ✅ 90%+ single-pass varnish removal efficiency
- ✅ Highest dirt-holding capacity in class
- ✅ Lowest cost per gram of contamination removed
Why It Works:
| Feature | Benefit |
|---|---|
| CJC Depth Media | Removes oxidation byproducts before they stick |
| Insert life monitoring | Know exactly when to change |
| Online monitoring available | Track Oil Health and ISO counts in real-time |
| No chemicals or beads | No messy changeovers or chemical management |
| Universal compatibility | Works with any turbine, any oil, any temperature |
| Built on 65 years of proven results | Trusted across power gen, refining, and heavy industry |
What’s the Risk of Doing Nothing?
- Sticky servos, pump failures, and control instability
- Increased MPC/UC = increased varnish load
- High maintenance costs and reduced asset life
- Unplanned shutdowns (when the plant can’t afford them)
Varnish doesn’t go away on its own. It builds up—until your equipment breaks down.
A Smarter Path Forward
You don’t need to flush your systems. You don’t need to rip out sensitive components.
You just need to:
- Install a CJC HDU or VRU system
- Run it 24/7 in bypass or offline mode
- Maintain insert life based on monitored values
- Enjoy consistent cleanliness, reliability, and long oil life
Stop Scrubbing. Start Preventing.
If you’re tired of band-aids, chemical flushes, or unexplained failures—this is your solution.
