EMI Suppression: Proper shielding reduces the risk of electromagnetic interference with sensitive HVAC control boards and flame sensors

Industrial Construction: NEMA Type 4 rated aluminum housing protects internal components against dust and moisture infiltration

using original boiler parts like the 100233667 prevents the dangerous "whistling" or soot buildup often caused by degraded seals

delivering a reliable 1140 RPM to maintain static pressure requirements across the heat exchanger

reducing total system static and improving energy efficiency

Siemens Combustion THERMAL-75X75 Barrier R-407A EMI Suppression: Proper shielding reducesThe 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,
