Microchannel Condensers

API Heat Transfer is a major supplier of all-aluminum parallel flow condensers using extruded tubes. Brazed aluminum provides highly efficient, robust designs using lightweight all aluminum materials.

Custom Oil Coolers

Oil cooling requirements vary widely depending on the type of equipment and duty cycle required. We’ve specially selected fin and tube options to provide the exact performance and durability the application calls for. Whether its high viscosity start up or full temperature operation, our brazed aluminum oil coolers keep it cool. We carefully select each oil cooler to be compatible with your system and each product is carefully designed to provide you the best combination of heat transfer and pressure drop.

Aluminum Radiators

API Heat Transfer offers a wide range of brazed aluminum radiator styles and options. From small individual coolers to large complex engine cooling systems, from heavy duty bar and plate construction to plastic tank radiators, we have the right design for your mobile or industrial application. Our engineering team is continually developing additional fin geometries to improve heat transfer efficiency so we can meet or exceed your expectations.

Bar and Plate Radiators

Fins are laid between aluminum braze sheets and fitted with header and face bars. The assembled unit is placed into one of our modern brazing furnaces where precise control of time and temperature produces a unified core. Manifolds designed to meet each customer’s particular piping requirements are welded into place to complete the radiator.

  • Ideal for heavy duty mobile and industrial applications
  • Feature a wide variety of thermally efficient internal and external fin patterns
  • Rugged, compact, lightweight units
  • Infinite number of core configurations and sizes to custom design a solution specifically to your exact requirements
  • Combi-cooler designs are available to cool multiple fluids in a single brazed unit
  • Available as component cooler or packaged as a complete cooling system incorporating radiator and/or charge air cooler with oil cooler components

TBAR  Radiators

Our patented TBAR replaces hot fins and bars with a single extruded tube for increased product durability.

  • Highly flexible design
  • Enhanced extruded tubes for improved charge air cooling
  • Patented tube-to-bar joint ensures consistent brazing
  • Extruded tubes provide unrivaled durability and fewer leak paths
  • High-efficiency louvered fins for enhanced heat rejection
  • Wide variety of debris resistant non-louvered fins
  • Welded tank to core for a long leak-free service life
