SWG200 – Continous Emission Monitoring System
The MRU SWG 200 CEM is a high-performance stationary gas analyzer for continuous flue gas and emission monitoring in industrial applications such as engines, boilers, and waste-to-energy plants.
Key Features :
-
Simultaneous NDIR measurement of up to 8 gases, including NOx, CO, CO₂, SO₂, CH₄, N₂O, C₃H₈, and O₂.
-
Uses advanced NDIR technology with excellent accuracy and zero-drift performance.
-
O₂ measured via electrochemical or paramagnetic sensor.
-
Includes automatic calibration, zeroing, and a double-stage Peltier gas cooler with dual condensate pumps.
-
Optimized for cold/dry gas sampling with low sample flow (~1 L/min).
-
Stainless steel cabinet, IP54-rated, with indoor/outdoor installation options.
-
Integrated data interfaces: RS485 (Modbus RTU), Profibus, Ethernet, USB, and SD card.
Applications :
- Natural gas/diesel engines
- Biomass and bagasse boilers
- Biogas/landfill gas CHP
- Cement outlet stacks
- Coal power stations, etc
In summary, the SWG 200 CEM is a robust and versatile analyzer ideal for demanding emission monitoring tasks, offering precise multi-gas detection and advanced data handling.
