Coolant Filters
Specialists
Cavitation erosion on cylinder liners costs thousands in premature overhauls. Coolant filters with SCAs (Supplemental Coolant Additives) protect wet-sleeve diesels and maintain inhibitor levels.
Why It Matters
What Coolant Filters Protect
Coolant filter elements contain SCAs — corrosion inhibitors, cavitation protectors, and scale preventers — that dissolve gradually into the coolant to maintain optimum protection levels.

Spin-on and inline coolant filter configurations
Test strips for coolant inhibitor level monitoring
Suitable for ethylene and propylene glycol systems

Bulk SCA additive for topping up as required
TechnologySCA-Charged Coolant Protection
Cavitation erosion on wet-sleeve cylinder liners is caused by vapour bubble collapse — a single liner failure can mean a full engine overhaul. Donaldson coolant filter elements contain SCAs (Supplemental Coolant Additives) that dissolve gradually into the coolant, maintaining protective inhibitor levels throughout the service interval.
