The Stinger UV-C fixture is designed to efficiently destroy surface microbes and degrade organic materials that impede HVAC system efficiency and contribute to allergies, poor IAQ, and airborne-transmitted disease. The Stinger keeps coils and drain pans clean and working. Because it mounts from the exterior and requires no interior unit access, the Stinger UV-C fixture is ideal for hard-to-access HVAC equipment up to 5 ton in size, including fan coils, heat pumps, unit ventilators, terminal units, or individual duct runs. Stinger’s components are water-resistant and are easily installed in most hard-to-access equipment. Simply create a small opening in any HVAC system, fan coil, plenum, or duct and install the reinforced, high-performance mounting base and neoprene gasket. The Stinger power socket utilizes a twist-on GU24 style connector for quick and inherently safe connections from soft-wired power or from its exclusive 24-V low-voltage power supply.
