Dioxin Emission Continuous Sampler

The increasing awareness of the dangers of compounds like dioxin, furans and POP’s for human health generated a compelling need for a better understanding of dioxin stack emissions.
Therefore, based on such requirements, TCR Tecora (Italy), designed and produced DECS, a Dioxin Emission Continuous Sampler, which is a fixed system for stack emission for determination of dioxins and furans on long term. The system is permanently installed on stack for continuous sampling from 8 hours up to 30 days. 

According to EN 1948 and USEPA 23, DECS adopts the filter condenser method with adsorbing trap on wet gas. DECS consists of 2 units: the sampling unit and the control unit.
The sampling unit is the part to be mounted on the stack’s sampling point and its aim is the collection of the sample in its two phases (particulate and gas) without modifying its composition.
The control unit is the user’s interface that controls all system’s functions; it is usually located in a safe and easily accessible area.

Built in an industrial cabinet, it’s connected to the sampling unit through pneumatic and electrical connections. DECS manage the sampling fully in automatic, without man supervision.
Available interfaces are a 10” LCD graphic monitor, a keyboard, a compact flash and a Internet/Ethernet connection. Once the measurement is terminated, a summary report is produced, in order to calculate the concentration and evaluation of the measurement quality; a continuous record of the main parameters and anomalous situations it is also available. Extensive data log can be downloaded via a USB key compact flash.
