Gaseous and liquid media significantly influence the behavior of the UUT. To ensure high precision and reproducibility in testing, conditioning systems are essential as they bring these media into a selectable and predefined range.
Stable environmental conditions are crucial for achieving accurate test results. Conditioning systems provide these stable conditions conveniently and reliably by using conditioned media. This stability is essential for maintaining test precision and reproducibility.
When UUT development occurs in multiple locations, media conditioning systems ensure that testing conditions remain comparable. This consistency is vital for reliable development, calibration, and certification processes.
Accuracy
High control accuracy in steady-state and dynamic mode increases testbed efficiency.
Reproducibility
Good reproducibility allows a fast achievement of development goals.
Conditions
Emulate/ Simulate/ Replicate extreme temperature and pressure conditions on the testbed which is hard to achieve on the road.
Automation
Easy integration into the automation system enables a quick installation (plug & play).
To accurately simulate extreme driving conditions on the testbed, thermal conditioning systems must create extreme media conditions. This capability is essential for conducting precise and effective tests.
Efficiency on the testbed is significantly enhanced by the timely establishment of initial conditions. Oil and coolant conditioning systems facilitate rapid cooling of the UUT at the conclusion of each test cycle. This rapid cooling process allows for an increased number of tests, such as cold start tests, to be conducted within a given time frame.
Key Features of our media conditioning systems:
- Modular Design: Our systems are designed to be modular, offering exceptional functional expandability to meet diverse testing needs.
- Compact and Mobile: The compactness of our systems ensures high mobility and versatility on the testbed, making them easy to integrate and use.
- Robustness and Durability: Engineered for maximum dynamics and control quality, our systems are exceptionally robust and built to last. With an installed base of over 4,000 systems, their quality and durability are well-proven.
AVL media conditioning systems are optimized for dynamic performance and control quality. They enable precise simulations and enhance the overall efficiency of the testbed by allowing more tests to be conducted in less time.

AVL ConsysCool Dynamic
The ConsysCool Dynamic revolutionizes the control of e-drive cooling fluids, ensuring precise adherence to temperature and pressure levels with unmatched accuracy and responsiveness of 6 K/s. It has a capacity of 20 kW to 60 kW and handles temperatures from -25°C to +120°C, providing flexibility for different test conditions. It integrates real-time simulation with hardware-in-the-loop (HIL), effectively simulating refrigerant circuits, e-motors, batteries, etc. This accelerates development by enabling testing of individual components and complete cooling systems, evaluating thermal comfort for parts and passengers under real-world driving conditions on a testbed before moving to more costly wind tunnel or road testing. Therefore, the ConsysCool Dynamic is a key feature of the AVL ThermalLab™.
AVL ConsysActive
Refrigeration units are critical to climatic testing, providing precise cooling for optimal test gradients while maintaining energy efficiency. The AVL ConsysActive products feature efficient compressor control, ensuring that testing conditions are met without excessive energy consumption. Our ConsysActive conditioning units are available with refrigerants with a Global Warming Potential (GWP) of less than 2500, and also in a CO2 version for environmentally friendly options. Air handling modules regulate the air within a walk-in climatic chamber or remote climatic box, ensuring consistent environmental conditions throughout the testing process. These features make ConsysActive an ideal choice for efficient, sustainable and accurate climatic testing solutions.
AVL ConsysCool
The AVL ConsysCool is a versatile solution for diverse testing needs, excelling in precise coolant temperature control for development, certification, end-of-line testing, and dynamic race car engine applications. It maintains strict temperature limits for optimal performance and reproducibility. Its integrated electric heating system enables rapid preheating and enhances control dynamics, offering high accuracy in both steady-state and dynamic modes. ConsysCool also provides additional options to meet specific requirements, with a cost-effective coolant conditioning unit available for less demanding tasks like endurance testing.
AVL ConsysBoost
AVL ConsysBoost ensures precise conditioning of the UUT’s boost air to a predefined temperature with exceptional accuracy, maintaining a constant boost air temperature regardless of the UUT’s operational state. The system replaces the original vehicle intercooler with an industrial water/air intercooler and features an adjustable flap to simulate pressure drops across various boost air coolers, ensuring compatibility with a wide range of UUTs. For cases where the original intercooler must be retained, AVL offers alternatives like spray conditioning systems and intercoolers integrated into water jackets, providing flexibility for specific testing needs.
