STACK 181

PS11 Capable Forward Scatter Particulate CEM

US EPA PS11 compliant ProScatter™ particulate CEM providing high quality emission measurement for low dust concentrations from industrial processes.

 

Utilising the patented ProScatter™ Forward Scatter measurement technique for measuring particulate concentration levels, typically between 0.06 mg/m3 to 300 mg/m3, this measurement technique offers improved levels of performance which make the STACK 181 very suitable for use as a PM CPMS or PM CEMS that need to comply with US EPA PS-11 for Site Operators looking to satisfy the recent MACT and MATS rules.

 

The STACK 181 is suitable for measuring particle emissions after both bag filter and electrostatic precipitator arrestment plant.

FEATURES AND BENEFITS

  • Robust design with no critical moving parts
  • Available for use in high-temperature stack conditions and Ex hazardous zones
  • Easy to fit multi-patterned flange
  • Adjustable monitoring depth to ensure sampling in the most representative part of the flow path
  • For use as PM-CPMS or PM-CEMS that need to comply with PS-11
  • ProScatter™ technology offers enhanced measurement due to reduced cross sensitivity of particle type and size
  • Features automatic zero and upscale checks that fully challenge the system’s ability to measure forward-scattered light and satisfy daily drift checks
  • Easily audited with manual filters
 
 

MAIN APPLICATIONS

  • Stacks after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration.
  • Non-condensing / dry flue gases
  • Incineration
  • Metals eg Steel/Aluminium
  • Minerals eg Cement/Gypsum
  • Chemicals eg TiO2 / Refinery
  • Power Generation Plant eg Coal/Biomass
