Field Controls 46361702 Lamp

The Field Controls 46361702 (Model UV-18) is a professional-grade 18-inch UVC germicidal lamp designed for 120Vac in-duct installations. This single-lamp system utilizes 254-nanometer ultraviolet-C spectrum energy to effectively neutralize airborne pathogens, including bacteria, viruses, and mold spores, as they pass through the HVAC plenum. The 30-watt high-output lamp is engineered for continuous operation, making it a reliable solution for maintaining indoor air quality (IAQ) and preventing biofilm accumulation on A-coils, which improves heat transfer efficiency and reduces long-term maintenance costs for the property owner.

From a contractor's perspective, the UV-18 system is built for streamlined installation. It includes a patented angle bracket and duct board mounting kit, allowing for flexible positioning in either the supply or return air ducts. The unit features a built-in viewport for safe verification of lamp operation and a standard 120V plug-in power supply, eliminating the need for complex hardwiring in many residential or light commercial applications. For peak performance, the 46365402 replacement lamp should be installed annually to ensure the UV intensity remains sufficient to disrupt the DNA of microorganisms. When handling the lamp, always use clean gloves or a cloth to prevent skin oils from creating hot spots on the quartz glass, which can lead to premature failure of the UV-Aire 46361702.

• High-Intensity Germicidal Output: Delivers 254nm UVC radiation to deactivate 90% of airborne microorganisms in a single pass at standard airflow rates.
• Versatile Mounting Options: Includes heavy-duty angle brackets and a duct board kit for easy integration into existing HVAC configurations.
• Reduced System Maintenance: When placed near evaporator coils, the UVC light prevents mold growth, keeping the HVAC coils clean and maintaining system efficiency.
• User-Friendly Monitoring: Features an integrated viewport lens that blocks harmful UVC rays while allowing the technician to confirm the blue glow of an active lamp.
• Simple Power Connection: Operates on standard 120Vac, 60Hz power with an included cord, simplifying the setup for UV-Aire air purification.

Where is the best location to install the UV-18 lamp?
For maximum benefit, install the lamp in the supply duct or directly over the AC indoor coil. This setup ensures that the coil remains free of fungal growth while purifying the air before it enters the living space. Ensure the lamp is at least 30 inches away from UV-sensitive plastics like flex duct or certain drain pans.

How do I know when the lamp needs to be replaced?
While the lamp may remain illuminated for a long period, its germicidal effectiveness significantly degrades after 9,000 hours of continuous use. It is standard practice for technicians to replace the bulb every 12 months during a scheduled maintenance visit to ensure the system meets performance specifications.

Is the power supply compatible with 240V systems?
No, the 46361702 is specifically designed for 120Vac/60Hz power. If you are working on a 24V or 240V system, you will need a different ballast assembly or a step-down transformer to prevent damage to the electronics.
