TOR POLLUTION CHECK INDUSTRIAL EMISSIONS Fixed system for dioxins sampling on stack emissions SYSTEM FEATURES DECS is an automatic sampling system, realized for permanent installation on stacks, dedicated to "long terms" Dioxins and Furans collection (PCDD/PCDF) and other POP's. • Sampling of PAH's with Filter/Condenser Method and adsorbing trap on the wet gas in accordance with methods EN 1948 and USEPA 23; • The Control Unit can manage up to 4 Sampling Units; • Distance between Sampling and Control Units can be up to 100mt • Fully automated sampling, no operator's presence required; • Preparation and washing operations are automatic; • Full Remote Control via Internet or Intranet; • The DECS can be easily upgraded to comply to other standards using the heated probe with out stack box for solid phase and side sampling for gas pahse such as for Heavy Metals, Hg and HCl. The DECS is composed by 2 units: • Sampling Unit • Control Unit Suggested distance between the two units is 50 meters The Sampling Unit is the part installed on the stack sampling point and is responsible for the sample extraction, without altering its composition, and collecting the solid and gas phases on the appropriate device. The Sampling Unit is composed by : • Heated Probe with interchangeable nozzle • Heated box for filterholder • Condensation system • Adsorbing Trap for XAD2 • Pitot Tube ( optional ) Process Characteristics • Stack velocity range: 3 -e 40 m/s • Stack Temperature: max 350 °C Water content: max 40% in volume Technical specifications may change without previous warning - Ed. 1

The sampling unit has been designed according to the following requests: - Ready to work in any moment - There is no need to put in or out the stack for each sampling - Particulate collecting filter enclosed in a heated box - Easy substitution of filter holder cartridge, adsorbing trap and collection devices - Made of Glass or Titanium - Designed for outdoor mounting - Applicable with DN 150 (on request DN 100) sampling port - Dimensions: 600 x 700 x 350 mm (w x h x d) - Weight: 37 Kg Control Unit The control unit is the interface between the sampling unit and the operator who leads all the...
