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.

Brazed 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
  • Zinc-infused aluminum materials for unrivaled corrosion protection
  • Low charge-air side pressure drop
  • Stands up to heavy thermal cycle loads

Tube and Header Radiators

Our brazed aluminum tube and header radiators offer a cost effective, lightweight solution for stationary and mobile engine cooling applications. Radiators can be provided as a stand alone component, but most often would be combined with our bar and plate oil coolers and charge air cooler to form a complete engine cooling solution.

  • Wide range of row depths
  • Variety of external fins to match different environmental conditions
  • Tanks designed to meet piping requirements and are welded into place for superior integrity
  • Welded aluminum tanks can be fabricated, stamped or cast depending on application and volume

Bar and Plate Heat Exchangers

API Heat Transfer’s line of air cooled all-aluminum brazed bar and plate heat exchangers are supplied as a vital component to our mobile and industrial OEMs’ products. Our flexible bar and plate construction allows countless core combinations and sizes, custom designed to your exact requirements with minimal or no tooling costs. Combi-cooler designs are available to cool multiple fluids in a single brazed unit.

Product types available.

  • Engine cooling systems
  • Charge air coolers
  • Radiators
  • Oil coolers
  • Aftercoolers
  • Combination coolers

Our bar and plate coolers feature a wide variety of thermally efficient internal and external fin patterns. 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 cooler. We can also supply cores when manifolds already exist or must be fitted in the field.

These rugged, compact, light-weight units are ideal for both on- and off- highway markets. API Heat Transfer can also add value beyond the component cooler by packaging a complete cooling system consisting of multiple coolers (e.g., radiator, charge air cooler, hydraulic oil cooler).

From small individual coolers to large complex engine cooling systems, API Heat Transfer will design and manufacture the heat transfer solution that’s right for you. Our engineering team is continually developing additional fin geometries to improve heat transfer efficiency so we can meet or exceed your expectations.

Our manufactured custom OE engine cooling modules for small gasoline engines to large-horsepower turbo diesel applications. Your choice of a variety of materials and core types (S-BAR, T-BAR, or P-BAR) offers design flexibility for high-performing radiators, CAC’s, or oil cooling. Full system modeling and validation of cooling modules is provided.

The Mobile AOC Series features DC or hydraulic fan drives and is ideal for low flow applications.  This cooler is a cost effective solution for power unit applications and is available in single or dual fan designs.  The dual rated (50/60 Hz) electric motor allows for application flexibility.  Removable air filters prevent air-side core blockage (clogging of fins with debris) and aggressive turbulators allow for optimal heat rejection at lower flow rates.

Consult catalog for additional sizes and technical information.

The low cost, high performance Mobile DH Series is an excellent choice for radiator face mount fuel or transmission cooling.  This series features moderate flows, high heat removal and an optional internal pressure bypass for cold start-up protection.  Material options are also available including steel tanks and steel fins for rugged off-highway applications.  Aggressive turbulators allow for optimal heat rejection at lower flow rates.

Consult catalog for additional sizes and technical information.

Mobile Air Cooled Copper Tube/Aluminum Fins Cores

The Mobile M Series heavy duty construction makes it one of the most rugged and robust heat exchangers in the Thermal Transfer Products family.  It features high flows and high heat removal with an optional internal pressure bypass.  The utilization of high/low turbulators allow for optimal heat rejection at lower flow rates.  The design of this series is ideal for face-mounting to radiators.  Common applications include oil, fuel and transmission cooling.

Mobile Air Cooled Copper Tube/Aluminum Fin with DC or Hydraulic Fan Drive Cooler

The Mobile MF Series is based off of the M Series with the addition of a low amp draw DC motor or long life hydraulic motor.  The robust and rugged design includes steel manifold, copper tubes, and aluminum fins.  Other features include an optional serviceable internal pressure bypass for cold start-up protection and the use of high-low turbulators for optimal heat rejection at lower flow rates.  This series is ideal for higher pressure applications.  Common applications include oil, fuel, and transmission cooling.
