UV-C lamps are a simple, cost-effective, and highly reliable technology that keeps HVAC systems running at ‘as-built’ conditions. Application guidance is found in ASHRAE’s handbooks, “Air Quality Guide,” and other technical articles. This article serves as an introductory guide for sizing and selecting UV-C systems for HVAC applications.
UV-C disassociates elemental bonds in organic matter, degrading them similarly to how UV light from the sun degrades vinyl and rubber, etc. UV-C eliminates biofilms, mold and fungi, and other organic contaminants on coils, drain pains, and plenum interiors.
