Cleaner oil is the foundation of reliable equipment performance
Permanently clean oil systems have a significantly lower probability of failure - because reliability starts inside the system.
Increase output, reduce maintenance costs, and extend machinery life
Industrial equipment is exposed to dust, moisture, heat, and mechanical stress, allowing particles, water, and oxidation residues to contaminate hydraulic, gearbox, and lubrication oils. This leads to reduced efficiency, higher wear, and unplanned downtime.
At C.C.JENSEN, oil filtration is not just about removing particles - it is about maintaining system stability, protecting components, and enabling predictable operation.
Why contaminated oil disrupts production
Unplanned Stops
Contaminated oil causes sticking valves, wear, and unstable operation - leading to unexpected stoppages and lost production.
Shorter Lifetime
Particles, water, and degradation products accelerate wear of components, reducing equipment lifetime and increasing replacement frequency.
Loss of Control
Oil degradation products such as varnish and acids lead to sticking valves, unstable pressure, and inconsistent system behavior.
Higher Maintenance
Increased maintenance hours, more spare parts consumption, and reactive repairs put pressure on maintenance teams.
Higher Cost
Unplanned downtime, higher energy use, oil changes, and spare parts increase total operating costs significantly.

Oil filtration for reliable industrial operation
Continuous offline filtration removes particles, water, humidity, and oil degradation products such as varnish and acids - helping critical equipment run efficiently with fewer interruptions
Key operational benefits
Fewer unplanned stoppages - Clean oil stabilizes system behavior, reduces wear, and prevents failures caused by contamination.
Longer lifetime of components and oil - Removing particles, water, and oxidation residues reduces wear and extends oil life by three to four times.
Lower maintenance effort and cos - Fewer breakdowns, fewer repairs, and fewer oil changes reduce workload and operating expenses.
More stable and efficient machine performance - Clean oil keeps systems running within their design tolerances, improving precision, output quality, and energy efficiency.
Reduced oil consumption and waste generation
When oil is kept clean and dry, it remains fit for service far longer. Continuous removal of particles, water, and degradation by-products slows oil ageing and prevents the rapid quality loss that drives premature oil changes. Across industrial applications, this results in significantly lower oil consumption and reduced volumes of waste oil that must be handled, stored, and disposed of.
Improved reliability of critical systems
Contamination affects more than individual components. Dirty oil disrupts valve response, impairs lubrication films, and increases friction across entire systems. By maintaining stable oil cleanliness, offline filtration supports predictable system behaviour, reduces process variability, and helps critical equipment operate reliably under fluctuating loads and harsh operating conditions.
Better control of long-term operating risk
Oil condition provides early insight into equipment health. Continuous filtration, combined with oil analysis, makes contamination trends visible and manageable before they develop into failures. This enables more controlled maintenance planning, reduces exposure to sudden asset damage, and supports long-term operational stability in asset-intensive industries.
Real world systems
Use Cases
“Since installation, no steel plates have failed quality standards.”
– Toyota Production Engineering
Toyota Press Line (Japan)
Toyota resolved quality issues caused by contaminated wash oil by installing a CJC® Fine Filter. Cleanliness improved from ISO 21/11 to 15/11, eliminating steel plate rejections and stabilising the washing process. Oil lifetime increased from 12 to 36 months, reducing waste and maintenance effort while keeping production performance consistent.
“Unplanned maintenance has dropped sharply, and uptime is noticeably higher.”
– Maintenance Engineer, Press Line
Press Forming Line (Europe)
A tin-cap forming press faced recurring unplanned maintenance due to dirty hydraulic oil. After installing a CJC® Fine Filter, cleanliness improved from ISO 22/20/18 to 17/16/13, and the frequency of unplanned stops dropped significantly. Maintenance intervals were extended, spare-part use decreased, and a second press was upgraded based on the proven results.
“The analysis clearly showed the efficiency of the CJC® filtration compared to mechanical methods.”
– Maintenance Manager, Metso Drives
Quench Oil System (Finland)
A heat-treatment line struggled with rapid oil degradation, sludge formation, and uneven hardening of large gear components. With CJC® Fine Filters installed, sludge was removed as it developed, black spots on surfaces disappeared, and process quality stabilised. More than 70 kg of contamination was captured within six months, reducing manual cleaning and improving consistency.
