Fleet Coolant/AntifreezeFleet Charge — Fully Formulated SCA-Precharged Coolant/Antifreeze for all Heavy-Duty Engines

Over 40% of diesel engine downtime is coolant related — Fleet Charge is the solution!

Fleet Charge Fully Formulated Antifreeze is designed to provide superior engine protection for heavy-duty cooling systems. For years, heavy-duty operators were limited to using low silicate automotive antifreeze that require the addition of a separate supplemental coolant additive (SCA) at initial fill and top off. While this was effective, it resulted in mixing errors when the SCA was added. To prevent SCA variability caused by mixing errors, and improve convenience, Old World Industries developed Fleet Charge Antifreeze.

Fleet Charge is a fully formulated universal formula antifreeze, having the advantages of low total dissolved solids, low silicate and incorporates nitrite to provide superior wet sleeve liner cavitation protection. Since Fleet Charge is precharged with a high quality SCA, there is no need to add additional SCA's at initial fill or when topping off to compensate for SCA dilution.

Additional advantages of Fleet Charge Antifreeze include its phosphate free formula that reduces the risk of scale, and state of the art corrosion inhibitors, which eliminates the need for expensive deionized water. The inhibitor system in Fleet Charge Antifreeze is designed to last for the life of the engine, when properly maintained with a high quality SCA filter system. As an added benefit, Fleet Charge meets the performance requirements of all major automotive specifications for conventional antifreeze, allowing operators of mixed fleets to stock one antifreeze for all their vehicles, simplifying fleet maintenance procedures.
