The FIREYE 85UVF1-1QDK3 is a complete flame detection kit featuring the flagship 85UVF1-1QD UV scanner with specialized installation accessories for hazardous environments. Designed for industrial burners exceeding 100 MMBtu/hr, this kit includes a forged 316SS adjustable mount, flame simulator tool, and explosion-proof conduit seals compliant with NEC/CEC Class 1 Div 1 requirements. The core 85UVF1-1QD scanner utilizes a military-grade UV phototube with nitrogen-purged optics to detect gas/oil flames through combustion turbulence or steam obscuration. With MIL-SPEC vibration resistance and continuous self-diagnostics, the FIREYE 85UVF1-1QDK3 ensures NFPA 85-compliant safety in co-generation plants, refinery heaters, and chemical process furnaces where false flame signals could trigger catastrophic events.

Main Features and Advantages
Hazardous Area Compliance: ATEX/IECEx-certified stainless steel mount and explosion-proof seals enable installation in Zone 1/21 areas where combustible dust/gases exist.
Quick Commissioning Kit: Integrated alignment sight and YQ9001-compatible simulator allow functional testing without live fire. Tool-less azimuth adjustment (±30°) simplifies targeting.
Active Contamination Defense: Nitrogen purge port maintains positive pressure, preventing process debris ingress. Self-cleaning quartz lens coating repels oil/carbon deposits.
Enhanced Diagnostics: Dual-color LEDs provide local flame/status indication. Phototube health monitoring alerts via 4-20mA signal drift detection.
Ruggedized Construction: All-metal conduit entries resist vibration fatigue. Military-spec shock absorption (50g @ 11ms) protects internal components.
Application Field
The FIREYE 85UVF1-1QDK3 secures combustion processes in classified areas. In LNG liquefaction plants, it monitors flare stacks where methane gas clouds require explosion-proof ratings. Petroleum coke calciners utilize its high-temperature tolerance in 180°C rotary kiln hoods.
For waste-to-energy facilities, the kit’s debris-resistant optics detect flames through fly ash clouds in mass-burn boilers. Offshore platforms deploy the 85UVF1-1QDK3 on wellhead heaters meeting API 14C safety requirements. Primary metal applications include aluminum melting furnaces where molten splash demands robust 316SS construction. Hydrogen production plants leverage its UV-specific detection for clean-burn flames invisible to IR scanners. Unlike standard kits, the FIREYE 85UVF1-1QDK3 includes NEC 500-compliant seals for North American refineries.
