Siemens Combustion THERMAL-75X75 Barrier 322055-301 Use with incompatible gases orThe Siemens Combustion THERMAL 75X75 is a professional grade thermal barrier engineered to protect Siemens QRA flame detectors from high ambient temperatures in industrial burner systems. Rated for continuous operation in environments up to 250F (121C), this 75x75 configuration acts as a critical thermal insulator between the heat source and the UV flame scanner housing. By mitigating thermal stress on sensitive internal components like the UV cell,
