IV. TR-9200 Features

1. The system structure is designed as an integrated analysis cabinet according to turnkey engineering requirements, achieving advanced levels in terms of technology, applicability, reliability, and safety comparable to domestic and international counterparts.

2. Utilizes specially designed stainless steel fiber sintered microporous sampling filters inspired by aerospace technology, replacing traditional ceramic or silicon carbide filters. Features strong regeneration capability, high filtration efficiency, and extended on-site maintenance cycles.

3. Employs Programmable Logic Controller (PLC) to achieve automatic purging of sampling pipelines and probes, timed automatic sampling, and partial self-diagnostic functions, enhancing the system's automation level.

4. The pretreatment system adopts a special design with multi-stage dust filtration, combining coarse and fine filtration. Long-term field operation demonstrates effective resolution of challenges such as high maintenance and low online continuous operation rates under high-dust and high-humidity conditions, extending system runtime.

5. Incorporates dry process flow, pulse cleaning, electric tracing heat, and programmable control technologies, enabling automatic sampling, continuous operation, and control interlock functions.  Jia Weihao 15891421187  18789429991 15891421187
