Multi-Platform EGR Coolers

August 8, 2017 - Products


BorgWarner series of multi-platform exhaust gas recirculation coolers are designed to offer durability and flexibility in a variety of engine applications.

The company’s modular cooler family includes four adaptable standard designs for flexibility across a range of engine sizes from 2 to 16 liters of displacement. The EGR solution offers resistance to thermal fatigue and improved coolant distribution for durable performance, even with minimum coolant flow, while reducing NOx emissions.

Featuring hybrid tube heat transfer technology and a floating inner core, BorgWarner’s EGR coolers are designed to resist high levels of thermal load. BorgWarner integrated a thermomechanical damper into the design to facilitate complete decoupling of the shell and inner core components to absorb longitudinal and angular differences for improved durability. The damper also provides some initial extra cooling for the inlet gas to reduce thermal shock and allows better gas distribution to the tubes to resist thermal fatigue.

When the system is operated at an exhaust gas temperature of 1,562 degrees Fahrenheit, the inlet gas box temperature is kept below 392 degrees Fahrenheit, compared to more than 1,292 degrees Fahrenheit without cooling, according to BorgWarner.

The four new coolers allow the standardization of most of the components from one application to another, with the exception of the housing and the mounting fixtures, resulting in better adaptability.
