THE MOBILE THERMAL MANAGEMENT CHALLENGE

Mobile and off-highway equipment operate in high-vibration, high-dust, and high-load environments where cooling system failure directly impacts uptime and productivity.

Extreme Environments.
Heavy-Duty Cycles.
Zero Room for Overheating.
API Heat Transfer - 1 Heat Icon
Thermal Density in Tight Packages
Modern engines and hydraulic systems generate significant heat in increasingly constrained packaging envelopes. Cooling systems must maximize airflow and heat rejection within tight space limitations.
Compact packaging — maximum heat rejection
Shockwaves Icon
Built for What the Field Throws at It
Off-highway equipment faces dust, debris, shock loads, and wide temperature swings. Cooling modules must be engineered for structural durability and long-term field reliability.
Dust, debris & shock load rated

Downtime Is Not an Option
Systems must balance thermal performance with service access, cleanability, and long-term durability to reduce total operating cost across the equipment's full lifecycle.
Designed for serviceability & low TCO

Engineered Around Your Application.

API designs cooling systems to your specific duty cycle, packaging constraints, airflow limitations, vibration profile, and environmental conditions — not a one-size-fits-all platform. From single cores to fully integrated multi-core modules, we deliver production-ready systems built for long-term field performance.

API Heat Transfer - 1 Grid Icon Integrated Multi-Core Modules

Custom-configured cooling packages combining multiple circuits — radiator, CAC, hydraulic, transmission — into compact, production-ready modules that simplify installation and reduce system complexity.

Structural Icon Advanced Fin Technology

Engineered internal and external fin designs improve heat transfer efficiency and airflow management — delivering more thermal performance in less space.

API Heat Transfer - 2 Fin Icon Built for Durability

Every module is designed for vibration resistance, debris exposure, and extreme environmental conditions — from desert construction sites to muddy agricultural fields.

API Heat Transfer - 4 Cost Target Optimized for Cost & Manufacturability

Balanced engineering achieves the right combination of thermal performance, structural durability, serviceability, and cost efficiency for production-scale deployment.

Frequently Asked Questions

Common questions about Mobile Equipment heat transfer applications and API Heat Transfer solutions.

What heat exchanger products does API Heat Transfer offer for mobile equipment OEMs?+
API Heat Transfer’s AIRTECH® division is a leading supplier of aluminum brazed bar-and-plate heat exchangers for mobile equipment OEMs worldwide. Product offerings include radiators, charge air coolers (CAC/intercoolers), hydraulic oil coolers, transmission oil coolers, fuel coolers, and complete engine cooling modules. All are custom-designed to the OEM’s packaging, thermal, and performance requirements.
Can API Heat Transfer supply complete engine cooling modules for off-highway equipment?+
Yes. API Heat Transfer’s AIRTECH® division designs and manufactures complete engine cooling modules (ECMs) for off-highway equipment, integrating radiator, charge air cooler, hydraulic oil cooler, and other heat exchangers into a single assembly. This reduces OEM assembly complexity, ensures optimized thermal performance across all circuits, and simplifies serviceability in the field.
What materials does API Heat Transfer use for mobile equipment heat exchangers?+
API Heat Transfer’s AIRTECH® mobile equipment heat exchangers are manufactured from aluminum alloys using vacuum-brazing processes that produce lightweight, high-strength core structures. Aluminum alloy selection and cladding specifications are optimized for coolant compatibility, corrosion resistance, and thermal conductivity. Fin density, fin geometry, and core configuration are custom-selected for each application’s thermal and pressure drop requirements.
Does API Heat Transfer supply charge air coolers for turbocharged off-highway engines?+
Yes. API Heat Transfer’s AIRTECH® charge air coolers (also called intercoolers or aftercoolers) are designed for turbocharged and supercharged off-highway diesel and gas engines. Products are engineered for the inlet air temperature, pressure, and flow requirements of each engine application, with brazed aluminum bar-and-plate construction for maximum thermal efficiency in a compact package.
