Bullet Proof Diesel has released a new EGR cooler for Cummins ISX applications. The cooler features H-Core technology, which the company says was developed to resist the common causes of EGR cooler failure.

Bullet Proof Diesel says that the H-Core design allows for the natural expansion and contraction of cooling tubes inside the EGR cooler. This limits structural failure, which can occur at the end of the tubes, rupturing the EGR cooler, rendering it useless and leading to possible engine component damage. The H-Core construction also increases the surface area of the coolant tubes within the EGR coolers, making them more effective heat exchangers than other tubed designs, the company added.

The company says a more forgiving EGR cooler design is integral to the durability of the component. During the life of an engine, a “thermal event,” an occurrence in which sufficient coolant flow is prevented from reaching the EGR cooler, will cause a temperature spike within the unit that often leads to component failure.

Bullet Proof Diesel also offers EGR coolers for the Cummins 6.7L ISB, ISB-E, Cab & Chassis (Hose Clamp Version), Non-Cab & Chassis, ISL, ISC, QSL and L9 engines.
