Resideo UV100E1043 Air Treatment System

The Resideo UV100E1043 is a professional-grade ultraviolet air treatment system engineered for high-efficiency microbial reduction in residential and light commercial forced-air systems. Operating on a 120V dedicated circuit, this 18-watt single-lamp assembly utilizes UVC light technology to disrupt the DNA of airborne bacteria and mold spores as they circulate through the return air duct or over the evaporator coil. This unit serves as the direct replacement for UV100 and UV100E1043/U models, ensuring a seamless retrofit for existing installations. Designed for rigorous environments, the ballast and lamp configuration maintains a stable output within an operating temperature range of 30°F to 140°F inside the duct. By integrating this UV germicidal light into the HVAC plenum, contractors can significantly mitigate biological growth, enhancing overall indoor air quality and maintaining system cleanliness without restricted airflow.

Key Performance Benefits

• Microbial Inactivation: High-output 254nm UVC wavelength reduces concentrations of airborne bacteria and viruses.
• HVAC Component Longevity: Prevents bio-organic buildup on cooling coils and drain pans when positioned correctly.
• Broad Compatibility: Direct HVAC UV light replacement for legacy Honeywell and Resideo UV100 series units.
• Flexible Installation: Engineered for both internal duct mounting and external housing configurations.
• Energy Efficiency: Low 18W power draw allows for continuous operation with minimal electrical overhead.

Common Technical Questions

Is the UV100E1043 compatible with older UV100 systems?
Yes, this model is the official 120V replacement for the UV100 series, utilizing the same mounting footprint and electrical requirements.

Where should the lamp be positioned for maximum efficacy?
For airborne disinfection, install in the return air duct. For surface irradiation, mount the unit facing the upstream side of the AC evaporator coil.

Can this unit operate in high-temperature plenums?
The internal duct rating supports temperatures up to 140°F, making it suitable for most supply or return air locations in standard HVAC applications.
