Bar and Plate Heat Exchangers

Bar and plate construction is the most flexible, cost-effective path to custom thermal management solutions. API Heat Transfer’s comprehensive line of air-cooled, all-aluminum brazed bar and plate heat exchangers powers thermal management across mobile and industrial OEM applications worldwide.

The bar and plate advantage:

Unlike standardized coolers that force compromises, bar and plate technology enables complete customization. Fins laid between aluminum braze sheets and fitted with strategic header and face bars create cores tailored to your exact space, your exact thermal load, your exact flow requirements. Precise furnace brazing produces unified, pressure-sealed cores of exceptional strength. Custom welded manifolds meet your piping requirements, or we supply bare cores for field integration.

No two thermal challenges are alike. Bar and plate technology accommodates them all:

• Unique space envelopes and mounting configurations
• Specific thermal performance demands
• Custom flow paths and fluid distribution
• Multiple fluids in single combi-cooler units
• Varying pressure and flow rate requirements
• Harsh environmental operating conditions
• Rapid prototype-to-production cycles with minimal tooling

One platform, endless applications:

Bar and plate technology serves as the foundation for our broadest product range:

• Engine Cooling Systems – Complete thermal management for on-highway, off-highway, and industrial engine platforms
• Charge Air Coolers*– High-efficiency intercoolers for turbocharged and supercharged applications
• Radiators – Primary engine coolant coolers across all vehicle and equipment classes
• Oil Coolers – Dedicated cooling for engine oil, transmission fluid, hydraulic oil, and specialty applications
• Aftercoolers – Compressed air cooling for compressor discharge and pneumatic systems
• Combination Coolers – Multiple fluid streams cooled in a single braised unit, eliminating package complexity

Manufacturing excellence:

Our team has spent decades optimizing fin geometries for maximum thermal efficiency. Precision layering of fins between aluminum braze sheets, combined with strategic header and face bars, creates cores of unmatched thermal performance. Our modern brazing furnaces apply precise control over time and temperature, producing unified cores that are significantly stronger and more reliable than alternative construction methods. Manifolds are custom welded to your specifications, or bare cores are supplied ready for your field integration.

From component to complete system:

We supply individual cooler components—or we design and manufacture complete cooling systems integrating radiator, charge air cooler, oil cooler, fan, shroud, manifolds, and controls into one optimized thermal package. This systems approach eliminates compatibility guesswork and ensures coordinated thermal performance.
