ATEX FTIR Gas Analyser
atmosFIR EX is an ATEX certified gas analyser system for measurement of industrial gases in a Zone 1 or Zone 2 area, providing a complete EX certified gas measurement system that meets both the sampling of non-flammable and flammable gases, utilizing Protea’s multigas atmosFIR FTIR gas analyser platform.
The atmosFIR EX system is provided in a sealed stainless steel cabinet with a constantly controlled and monitored purge, providing a system that conforms to EN60079-2 purge type. A dedicated purge controller is mounted to the enclosure which provides control of the purge cycle and monitoring of the normal operating pressure, and with redundant microcontrollers this provides the redundancy required for a Zone 1 purge system.
Protea can provide an atmosFIR EX system for ATEX Zone 1 or Zone 2 installation. Zone 1 applications are often found when the analysis system has to measure flammable gases and the potential of an internal source of release has to be engineered in. This also will include the limitation of sample gas pressure will specifically designed sampling system by Protea.
The FTIR gas analyser in the atmosFIR EX system is the atmosFIR multigas FTIR, capable of the instantaneous measurement of hundreds of gases. Be it for emissions monitoring from standard combustion processes (NOx, CO, SO2, HCl), multiple VOC emissions measurements or process control measurements, such as siloxanes from landfill gas, the power of Protea’s FTIR analyser means the atmosFIR EX system can be used across multiple applications.
Please Contact Protea to discuss the gases required to be measured with the FTIR gas analyser in your ATEX application.
Multipoint gas analysis is part of the atmosFIR EX system design, with the measurement of up to 12 sample points, with automated sequential control from PAS-Pro FTIR analyser software. This allows, for example, the measurement of both process gas measurement and emissions monitoring with the one analyser system. For ATEX Zone 1 applications requiring the measurement of flammable gases, the management of the internal source of release requires external ATEX certified sample control valves mounted to the exterior of the atmosFIR EX rack.
The industrial PC controlling atmosFIR EX gives the option of remote control of the system via Modbus protocols, OPC Server or Remote Desktop applications. Data is saved continuously, with separate data logs per measurement stream.
