At AEI, our state-of-the-art cold/hot chamber testing facilities are designed to meet the rigorous demands of modern vehicle and component testing. Our cold/hot chambers provide an unparalleled environment for simulating extreme temperature conditions, ensuring that your products perform reliably in the harshest climates.
Extreme Temperature Range
Our cold/hot chambers are capable of cold/heat soaking your test engine, truck, battery, and more to temperatures as low as -60°F and heating up to 140°F. This wide temperature range allows for comprehensive testing across various conditions, from arctic cold to desert heat.

Versatile Chamber Configurations
Our chambers are adaptable, offering two different sizes to suit your specific testing needs:
- Large Configuration: 49′ x 19′ x 17′
- Compact Configuration: 24′ x 19′ x 17′
With these options, we can accommodate a variety of vehicles and components, ensuring a perfect fit for your testing requirements.
Convenient Access

The chambers are equipped with a 14′ x 14′ door, providing easy access for larger vehicles such as buses and semi-trucks. This feature ensures that even the largest test subjects can be driven directly into the chamber, streamlining the testing process and reducing setup time.
Advanced Testing Capabilities
Our cold chambers are not just about temperature extremes; they also support a wide range of testing scenarios, including:
- Idle Engine Operation: Maintain steady temperatures during idle to assess engine performance and durability.
- Regen and Desorb Cycles: Simulate real-world conditions for emissions control systems, ensuring they function correctly under all temperature conditions.
- Hybrid Vehicle Testing: Evaluate the performance and efficiency of hybrid systems under extreme temperatures, from battery management to powertrain performance.
- Hydraulic Development: Test hydraulic systems for reliability and performance in both cold and hot conditions, critical for ensuring operational integrity in diverse environments.
Motoring Dynamometer Integration
For enhanced testing capabilities, our cold chambers can be equipped with a motoring dynamometer. This option allows for precise control and measurement of engine and drivetrain performance under extreme temperature conditions, providing invaluable data for vehicle development and optimization.
At AEI, we are committed to delivering top-tier testing solutions that meet the needs of today’s most demanding automotive and industrial applications. Our cold chamber facilities are a testament to this commitment, offering the flexibility, precision, and reliability you need to ensure your products perform at their best, no matter the environment.
