When it comes to fuel integrity, reliability is everything - especially for industries where backup power is mission-critical. That's why MLA Filtration, in collaboration with its fuel polishing specialist WASP PFS, offers cutting-edge Fuel Polishing Systems that safeguard your operations in ways that matter.
What Is Fuel Polishing - and Why Does It Matter?
Fuel polishing is the process of circulating stored diesel fuel through multi-stage filtration, purging water (both free and emulsified), particulates, and microbial contamination to restore and maintain fuel quality. Over time, diesel fuel degrades due to condensation, sedimentation, fuel bug growth, oxidation, and sludge formation - factors that compromise engine performance and reliability.
