Charge-Air Products

The trend toward smaller sized engines producing higher horsepower places increased stresses on critical performance components such as turbochargers and charge-air coolers. Boost pressures have driven cooler inlet temperatures from around 325°F during the 70’s and 80’s, to over 400°F in later model engines.

A typical cooler operating with slightly over 400°F inlet temperature will drop the boosted air’s temperature to just over 100°F before it enters the engine. This drop of nearly 300°F causes extreme thermal stresses from expansion and contraction of the entire structure. These stresses along with engine load variances and chassis vibrations cause frequent fatigue failures on OEM type tube & fin constructed coolers.

Choosing which charge-air cooler is best for your diesel engine is why we are here. They're many options when attempting to solve your charge-air cooler issues, but only one will get you back up and going at the highest quality, this is the Av-Tekk solution.
