MEASUREMENT TECHNOLOGY IN RECYCLING In-process oxygen measurement for recycling processes

Oxygen measurement controls inerting efficiently In aerosol recycling processes, O₂ measurement helps control inerting efficiently.  Use N₂ only when needed Know the real O₂ value instantly Normal O₂ level EFFICIENT CONTROL Lower O₂ with nitrogen until the measured value reaches the target range. Measure, then dose  only as much N₂ as required. Nitrogen addition lowers O₂ Target range for controlled inerting 4 Efficient operating area 0

Example shredder process with extractive O₂ measurement

Regulation already points to continuous oxygen monitoring Oxygen is a process safety signal — not just a reporting value. UK guidance for aerosol treatment supports inerted operation, shutdown on high oxygen, and continuous monitoring of key process parameters. Controlled inert atmosphere Continuous monitoring Plant operation should cease if oxygen rises too far. O₂ belongs alongside pressure, airflow, nitrogen, and LEL. Nitrogen and gas extraction are part of the safety concept. Source: UK Environment Agency guidance for the storage and treatment of aerosol canisters and similar package

GA 210 O2 for continuous process measurement FRESENIUS GA 210 O2 Paramagnetic O₂ measurement for demanding recycling and process-gas applications. Stable, continuous oxygen analysis for harsh mixtures and robust industrial operation. MEASUREMENT MODE UPDATE INTERVAL OFFSET DRIFT Selective O₂ analysis in complex gas mixtures. Measuring cell lasts longer than consumable sensor concepts. Long-term stability Suitable for harsh mixtures ≤ ±0.1 Vol.-% O₂/week (offset) for reliable operation. A strong fit where aggressive gases or organics make zirconia less suitable. No laser-based setup Avoids laser-specific...

Why paramagnetic is the better fit here In harsh recycling atmospheres, paramagnetic O₂ measurement brings practical advantages. Especially where the process involves flammable mixtures, aggressive gases, continuous operation, and real industrial vibration. No laser-based setup Helpful where export or application complexity matters. No consumable sensor Supports long-term use with predictable service effort. Better than zirconia A stronger fit for flammable, organic, toxic and difficult gas mixtures. Built for industry Robust for continuous operation in demanding enviro

CFC emissions monitoring in recycling We can also monitorCFC-related emissions. • Continuous monitoring in selected emission streams • Supports emission control and process transparency • Suitable for recovery, separation and exhaust points

Smart Control 300 GAS-BASED SORTING IN REAL TIME Identify the gas. Choose the right recycling line. Smart Control 300 determines which gases are present in the refrigerator and supports the correct treatment path. ⚡ Immediate result Identify which gases are present in the refrigerator. Use the result to assign the correct recycling path. Send the refrigerator to the appropriate recycling line. No waiting times — get the substance immediately for a quick process. This enables automated line selection instead of manual sorting dec
