Test and Barrier Air Supply – Dynamics of Energy Conversion

Compressor Station for Experimental Air and Barrier Air Supply

A specially designed compressor station is required to set the pressure level in the test air circuit during closed-loop operation of the compressor station and to supply various subsystems and test benches. It provides the necessary compressed air quality and quantity to ensure stable and reproducible operating conditions.

Technical Equipment and Operation

The compressor station is equipped with two multi-stage, oil-free screw compressors designed for continuous operation under variable load and pressure conditions. The oil-free compression process ensures high purity of the process air, which is particularly important for sensitive measurements.

The high purity of the process air supplied is particularly important for thermodynamic investigations. The compressor station is integrated into the test facility's central control and monitoring system, enabling automated and reproducible operation.
