Contamination solutions that drive results
CJC products are designed to tackle big problems
Dirt and Particles
Dirt and wear particles in your oil act like sandpaper inside your equipment — grinding away at pumps, valves, and bearings. Leading to increased wear, higher maintenance costs, and unexpected downtime. With proper filtration, you can drastically reduce these risks and extend both oil and equipment life.
Water
Even small amounts of water can cause rust, reduce lubrication, and accelerate oil degradation. This leads to premature failure of bearings, gears, and other critical components. With effective offline filtration, you can remove free, emulsified, and dissolved water — protecting your equipment and maximizing reliability.
