Siemens Combustion THERMAL-75X75 Thermal Barrier For QRA 250°F

The Siemens Combustion THERMAL-75X75 Thermal Barrier for QRA is a protective component used in HVAC systems that provides durable performance up to 250°F. It is used in HVAC burner systems and industrial combustion equipment primarily to protect sensors from heat damage, to improve the accuracy of flame monitoring, and to increase the system's safety. Without this thermal barrier, the detector life would be shortened, maintenance would be increased, and signal loss from heat exposure would occur it is a better addition to having an efficient and consistent heating operation in demanding applications.
