Description

MRU SWG300 – Continous Emission Monitoring System
Precision Emissions Monitoring for the World’s Toughest Industrial Environments

The MRU SWG 300 is a state-of-the-art stationary flue gas analyzer designed for 24/7 continuous emissions monitoring in highly demanding industrial sectors. Whether you’re operating in a coal-fired power plant, waste incinerator, cement kiln, glass furnace, or biomass/solid fuel boiler, the SWG 300 ensures that your facility remains environmentally compliant, efficient, and safe—even under the most extreme process conditions.

Key Features :

  • Simultaneous measurement of up to 8 gases using optimized NDIR technology: NO, NO₂, SO₂, CO, CO₂, N₂O, CH₄, C₃H₈.

  • Oxygen (O₂) measurement via long-life electrochemical or paramagnetic sensor.

  • True NOx and SO₂ detection with heated gas sampling and acid mist separation.

  • Fully equipped gas conditioning system: Peltier gas cooler, heated filters, acid mist drain, and back-purge functions.

  • Data interface: RS485 (Modbus RTU), Profibus, Ethernet, USB, and SD card.

  • Low gas flow (50 l/h) improves system efficiency and conditioning performance.

  • Automatic calibration with up to 6 calibration gas cylinders.

  • Available in IND (indoor), OTD (outdoor), and Ex (Zone 2 hazardous area) versions.

Applications :

  • Power generation

  • Waste incineration

  • Cement & glass industries

  • Heavy oil & biomass combustion

The SWG 300 is built to handle acid mist, high dust, and extreme temperatures, making it one of the most robust solutions for reliable and accurate emissions monitoring in demanding industrial processes.
