No More Corrosion in the Engine Cooling System
The cooling system, which prevents the engine from overheating, can develop rust, scale, and sediment over time. micronic Filter coolant filters do not just strain solid particles; they also maintain the pH balance of the coolant through their chemical additives (SCA – Supplemental Coolant Additives). In this way, they prevent cavitation (pitting/erosion) on cylinder liners, avoid radiator clogs, and ensure the engine operates at the ideal temperature.





Coolant Filter for Diesel Engines
The cooling system, which prevents the engine from overheating, can develop sediment and scale over time. micronic Filter coolant filters maintain the pH balance of the fluid with their chemical additives (SCA), prevent cavitation (erosion/pitting), and avoid radiator clogging.

Frequently Asked Questions
“SCA Charged” filters contain Supplemental Coolant Additives that replenish protective chemicals lost over time in the coolant. “Blank” filters do not contain SCA and are used when the system already has sufficient additives or when additional protection is not required.
Coolant filters protect the engine's heat management, performance, and lifespan by removing rust, scale, metal particles, and other contaminants from the system. Additionally, some filters maintain chemical balance to prevent corrosion and cavitation.
micronic filters effectively capture harmful particles using high-efficiency filter media technology. Furthermore, they offer long service life and high durability thanks to their internally coated canister structure, the use of plastic insulators, and a heavy-duty centertube design.
The primary components include the filter media, centertube, end caps, base plate/seaming lid assembly, compression spring, canister body, plastic insulator, and SCA pellets. Each component works together to enhance filtration quality and system reliability.
If the coolant in the system already contains sufficient or excess SCA, no additional additives should be added. In this case, a “Blank” filter should be preferred. Otherwise, over-treatment can lead to chemical imbalance.
The plastic insulator prevents the compression spring from making direct contact with the canister body. This prevents metal wear, noise, and particle formation, thereby extending the life of the filter. This feature is standard on all micronic spin-on coolant filters.
