KLAROL oil cleaning systems

02/08/2026

Klarol Cooking Oil Purifier cleans frying oil continuously even when the fryer is operating with cooking oil temperatures at 180 degrees centigrade or more. Made with stainless steel this machine uses fine filters to keep oil free from carbon fines down to less than 25 microns. Frying oil filtration helps to reduce the oxidation of cooking oil and hence helps to increase oil life. Keeping frying oil clean helps to ensure better food quality, ensuring crispness, better taste, longer shelf life and less absorption of oil.

Why Offline Oil Filtration Works

Offline or kidney-loop filtration continuously cleans hydraulic oil while the machine remains in operation. Unlike standard return-line filters, offline systems can remove fine contaminants without interrupting production.

Key benefits include:

* Longer servo valve life
* Reduced pump wear
* Lower maintenance costs
* Fewer unexpected breakdowns
* Extended hydraulic oil life
* Improved machine reliability

Best Practices for Reliable Servo Valve Performance

To maximise servo valve life:

* Maintain the recommended ISO 4406 cleanliness level.
* Monitor oil condition through routine particle counting and oil analysis.
* Remove water before corrosion or oxidation begins.
* Control varnish formation through proactive oil conditioning.
* Replace filter elements at the recommended intervals.
* Install dedicated offline filtration systems for critical hydraulic equipment.

Conclusion

Servo valves represent a significant investment, and their reliability depends heavily on oil cleanliness. A proactive contamination control programme—including effective filtration, regular oil analysis, water removal, and varnish management—can dramatically reduce failures, improve machine performance, and lower maintenance costs.

At Klarol Filters, we help industries improve hydraulic system reliability through advanced oil filtration, dehydration, and oil conditioning solutions. Clean oil is not just about extending oil life—it is about protecting the equipment that keeps your plant running efficiently.

The Hidden Problem: Varnish

Many engineers focus only on solid particles.

However, oxidation by-products dissolved in oil eventually form sticky varnish deposits. These deposits cause servo valve spools to stick, especially during temperature fluctuations.

Traditional filters cannot remove dissolved varnish precursors.

A complete oil conditioning program should therefore include:

* Fine particle removal
* Water removal
* Varnish mitigation
* Routine oil cleanliness monitoring

Benefits of Continuous Oil Filtration

Installing an offline kidney-loop filtration system allows oil to be cleaned continuously while the machine remains in operation.

Benefits include:

* Reduced unplanned shutdowns
* Longer servo valve life
* Improved machine accuracy
* Reduced hydraulic pump wear
* Lower maintenance costs
* Longer oil service life
* Improved equipment reliability
