The Stinger ultraviolet fixture from UV Resources is a water-resistant, easy-to-install tool designed to efficiently destroy surface microbes and organic materials that hinder HVAC system efficiency and contribute to allergies, poor indoor air quality and airborne-transmitted disease, officials say.

Because the low voltage unit mounts from the exterior and requires no interior unit access, the Stinger UV-C lamp series is ideal for hard-to-access HVAC equipment up to 5 tons.
