The Process exhaust air is sucked at a pressure of 700m barg at the process temperature using an insulated heated sampling probe. The gas sample passes through this tube which has a high enough temperature maintained to keep the sample air above its dewpoint temperature and avoid any condensation to ensure accurate measurement. The sampling tube is ATEX certified for zones 1/2 & 21/22.. 

Using GreCon Systems ATEX can provide a custom engineered spark detection system to detect and suppress sparks and burning embers as they travel down ductwork preventing them from entering process equipment and causing an explosion
