Hot gas sampling line, for pollutant analysis, comprises sealed isothermal housing protecting sampling unit with multidirectional head and trap

摘要

The sampling line comprises a sealed isothermal housing protecting a sampling unit with trap connected to an upstream multidirectional exterior head and downstream to a variable flow suction apparatus. The sampling unit is cooled by circulated air flow from a separate cold air generator/compressor, fed through an flexible pipe made from a reticulated supple polymer in a synthetic rubber-based cellular sleeve. The sampling line comprises a sealed isothermal housing (1) protecting a sampling unit (2) with a trap (3) connected to an upstream multidirectional exterior head (4) and downstream to a variable flow suction apparatus (5). The sampling unit is cooled by a circulated air flow from a separate cold air generator and compressor, fed through an insulated flexible pipe (8) made from a reticulated supple polymer in a synthetic rubber-based cellular sleeve.
