MEDAS Altitude Simulation

Dynamic Altitude Simulation

The MEDAS system is a compact altitude simulator that reproduces a wide range of environmental conditions. It allows for testing light- to heavy-duty vehicles, including Non-Road Mobile Machinery (NRMM). It is ideally suited for a range of testing applications, such as durability, RDE replication, emission tests and mapping as well as tests from component to vehicle level. The patented technology inside the MEDAS system allows dynamic changes on the simulated atmosphere with high accuracy. The system can also be moved between different test cells due to its compact design.

MEDAS enables measurements up to 5,000m with a simulated temperature range from -45 to 50 °C (with the MEDAS Temperature Module) and a simulated humidity range of 5 to 95 % (with the MEDAS Humidity Module).

  • Suitable for different test cell configurations (e. g. engine, vehicle, powertrain)
  • Full integration with test cell control through CAN
  • Two MEDAS systems can be coupled in parallel to multiply the mass flow
  • No limit on minimum engine flow rate
  • Additional options available, e. g. noise insulation


Key Benefits 

From Road to Laboratory

The MEDAS system increases flexibility by offering a modular design, which can be adjusted for a wide range of different test environments and possible applications. It allows any worldwide atmospheric condition to be reproduced inside the test cell. For a complete real driving correlation (such as emissions correlation), an integration with other testing equipment is possible.

FLEXIBLE  

  • Flexible concept with extended temperature and humidity modules
  • Can be moved between different test cells
  • Suitable for a wide range of applications, from light-duty (e.g. motorcycles) up to heavy-duty engines, including NRMM


  DYNAMIC  

  • Can simulate changing ambient pressure, temperature and humidity
  • Very fast response time for replication of real driving tests


EFFICIENT  

  • Precise and repeatable, even during high engine dynamics
  • Patented design and internal algorithms reduce power requirements while ensuring robust results
