In situ dust CEMS analyzer D-R 808 long probe
In situ dust monitor D-R 808 Ex

D-R 808
In situ dust monitor

Certified and approved PM CEMS providing very high quality monitoring of very low to medium particulate concentrations in dry flue gas flows.


Technology: Forward scattering

  • Certified for the range of 0-7.5 mg/m3 the lowest range achievable for a dust CEMS (Continuous Emissions Monitoring System)
  • Certified and approved dust analyzer for ensuring plant compliance with international standards for industrial emissions
  • New: ATEX & IECEx certified to operate safely in hazardous environments, minimizing the risk of ignition and explosion

 

COMPLIANCE & CERTIFICATIONS

Certifications

  • TÜV certified to EN 15267-1:2009, EN 15267-2:2009, EN 15267-3 :2007, EN 14181 :2014
    • QAL1 as defined by EN14181
    • QAL3 compliance to EN14181
  • MCERTs certification for "Stack emissions monitoring equipment at industrial installations” – Continuous emissions monitoring systems (CEMS)
  • ATEX (optional):
    • II 3G Ex ec nC op is IIC T4 Gc
    • II 3D Ex op is tc IIIC T100 °C Dc
  • IECEx (optional):
    • Ex ec nC op is IIC T4 Gc
    • Ex op is tc IIIC T100 °C Dc
  • US EPA capable as a PM-CEMS or PM-CPMS
  • Compliant with US EPA 40 CFR 60 PS 11

 

Supporting compliance with international environmental legislation, such as:

  • Advanced measurement accuracy:
    Utilizes forward scattering technology to minimize cross sensitivity to particle type and size
  • Suitable for high temperature stacks and hazardous Ex zones:
    Designed to operate effectively in extreme conditions
  • Single side installation:
    Eliminates the need for optical alignment, making it ideal for thick-walled or double-walled ducts
  • User-friendly flange: 
    Easy installation and maintenance; Simply unscrew, turn slightly, and remove the instrument from the stack/duct
  • Simplified audit process: 
    Allows for easy verification with manual filters, ensuring consistent and accurate performance checks without removing the device from the stack
  • Status-dependent indicator light on the analyzer: 
    Changes color to reflect the operational state of the analyzer, providing clear and immediate visual feedback
  • Pressure-controlled purge air system: 
    Ensures that the particulate analyzer remains safeguarded in the event of a blower or plant instrument air system failure 
  • Durable construction with no moving parts in the flue gas flow: 
    Ensures long-lasting reliability and minimal maintenance
  • Reduced maintenance and operational costs:
    The robust design and minimal maintenance requirements significantly lower the overall cost of ownership and operation

Typical applications:

Suitable for process applications and for emission compliance for plants equipped with bag filters, cartridge filters, cyclones, electrostatic precipitators, or without any filtration

  • Ideal for monitoring non-condensing / dry flue gases
  • Monitoring of dust arrestment filter plants
  • Monitoring of ventilation systems

Industries:

  • Waste to energy plants
  • Metal industries, including steel and aluminum production
  • Mineral processing, such as cement and gypsum manufacturing
  • Chemical industries, including TiO2 production and refineries
  • Power generation plants, including coal, gas and biomass plants
  • Technical data
  • System components
  • Explosion protection
