Our H-Core Technology - What's the difference?

It isn't easy to get a new patent on a heat exchanger, but we did! That's how unique and different our heat exchanger technology is. Most EGR coolers are designed with rigid, unforgiving channels filled with fins. H-Core EGR coolers are designed to forgive and flex, rather than resist and break. This translates to EGR coolers that stand up to the daily grind even when thermal events (water pump failure, coolant leaks, etc) do their best to damage critical components.

A conventional channel and fin EGR cooler is shown in the upper right and the Bullet Proof Diesel H-Core technology is in the lower left. See the difference?
