Global Heat Transfer has been replacing CAT™ cores since we opened in October of 1978.
We’ve spent years learning what works in the design and what needs to be improved.


*Some parts may not be available in stock. Please contact a GHT representative for current availability.

We now proudly offer replacement:

  • Folded Cores
  • AMOCS Cores
  • Modular Cores

After years of study and prototypes, we’ve designed our replacement cores to exceed the OEMs in many areas.

Here is a list of just some of the things we’ve done to improve the product:

  • Silver Soldered our tube to header joint and brazed our header to tank joint on the Folded Core Modules.  This adds significant strength to
    the core and improves the quality of the product
  • We use a 0.028” Tube Wall.  This gives us added Strength
  • Modular and AMOCS cores have soldered joints for ease of cleaning
  • Double tubed corners on certain models for added strength and rigidity where you need it most


Guaranteed Fit and Performance
We’ve made our CAT radiators a simple drop in replacement for you. After 12 months of development with one of the world’s largest CAT distributors we’ve proven the fit, form and function of the radiator and lines group so that you don’t have to do any of the design work yourself. Simply order the complete kit from GHT and be assured that when it arrives it’ll bolt up without a single modification required.
