Engine Cooling Capabilities
Modern aerospace and defence platforms generate significant thermal loads that can impact performance and reliability. Advanced engine cooling systems provide the airflow and heat rejection needed to keep engines, transmissions, and critical equipment operating in the most demanding environments.
Engine Cooling Systems Built for Demanding Military Vehicles
AMETEK Airtechnology has decades of experience designing and manufacturing complete engine cooling systems for military land platforms ranging from 4×4 light tactical vehicles to 8×8 IFVs, howitzers, light tanks, and even main battle tanks. Our cooling groups support engines from 200 to 1100 kW (250–1500 hp) and are engineered not only for engine cooling, but also for multiple thermal loads across the vehicle, including:
- Transmission oil
- Hydraulics
- Fuel systems
- Air conditioning systems
- Additional auxiliary cooling
These fully integrated systems offer platform flexibility, engine/transmission compatibility, and customised packaging, ensuring optimal airflow and thermal performance even in the most constrained spaces.
Designed for Extreme Environments
Built for high ambient and high altitude operation, AMETEK cooling systems are proven in the field with more than 5,000 units deployed in recent conflict zones. Their rugged design ensures reliability under sand, dust, shock, vibration, and temperature extremes, all validated to military standards.
Mixed Flow Fan Technology: The Heart of High Performance Cooling
At the core of many AMETEK systems is the industry‑leading MP4 mixed flow fan, available in three sizes—305 mm, 380 mm, and 475 mm—with multiple drive options including hydraulic, belt, shaft, and electric.
Key Advantages of the MP4 Mixed Flow Fan
- High performance with low power consumption
- Non‑stall aerodynamic characteristics
- Low noise emissions
- Excellent performance in dusty environments, with blades designed to stay clean and maintain efficiency
- Flexible discharge options (axial, centrifugal, or mixed flow) for easier integration into compact vehicle layouts
- Robust construction, meeting DEF STAN and MIL‑STD environmental requirements
These advantages make mixed flow technology ideal for modern tracked and wheeled combat vehicles where space, airflow, and thermal loads are increasingly demanding.
Next Generation Enhancements: Inlet Guide Vanes (IGV) / MP5 Technology
To push performance further, AMETEK engineers developed an Inlet Guide Vane (IGV) module that can be paired with existing MP4 fans to deliver an instant 15% boost in airflow and pressure. The newer MP5 aero design builds upon the MP4 platform, offering enhanced efficiency while maintaining the same footprint, making upgrades or platform refreshes far easier.
High Voltage Electric Cooling for Hybrid and Electric Vehicles
With the defence sector rapidly shifting toward hybrid electric and fully electric combat vehicles, AMETEK is introducing high voltage electric solutions for each of our range of engine cooling fans combining:
