Careful rebuilds for leaking coolers

Most hydraulic oil coolers, charge air coolers, and other air-to-air / water heat exchangers found in forestry and mining equipment are aluminum bar and plate coolers. We have the ability and the equipment to rebuild your leaking oil coolers with an upgraded extruded tube core.


We have several aluminum core suppliers to choose from in North America with one being located in the Upper Midwest. This American supplier is a small, family-owned factory that specializes in high-quality craftsmanship and delivers top-notch oil cooler cores.

Why rebuild your aluminum oil or air coolers?

We replace OEM bar-and-plate cores with a stacked extruded tube core, increasing strength immensely and also achieving improved cooling capacity and heat transfer efficiency. Typically OEM bar-and-plate charge air cooler tubes are built in four pieces and brazed together. Our cores use an extruded tube, which eliminates the common problem of tubes splitting.
