High-Grade Durability: Constructed from robust materials to resist corrosion and thermal fatigue

While the 85UVF4A is optimized for UV emissions from gas and light oil

The inclusion of Polyol Ester (POE) oil ensures superior lubrication and compatibility with modern refrigerant standards

technicians should verify the condition of existing seals or source the specific gasket kit for the furnace model number during repair

Can this be installed in any commercial boiler

Siemens Building Technology QFA3212.EWNN Sensor Els PW 29614 High-Grade Durability: Constructed from robustThe Siemens Building Technology QFA3212. EWNN Sensor is a precision engineered room relative humidity and temperature sensor designed for demanding commercial HVACR applications. Built for high traffic environments where tamper resistance is a priority, this no display (blank front) unit provides reliable environmental monitoring without the risk of unauthorized adjustments. It utilizes a capacitive polymer sensing element for humidity and a 1k Ohm
