STATE-OF-THE-ART ENGINE PROTECTION

Today’s diesel engines are more compact, operate at higher temperatures under increasing loads and have more emissions control equipment than their predecessors. Most importantly, engines and cooling systems are increasingly made from aluminum as opposed to cast iron.

HD Expert products powered by the ProShieldTM OAT Corrosion Defense system form chemical barriers that protect internal engine components from corrosion, cavitation erosion and scale that occur as water and glycol age and degrade in the cooling system.
