Modern UV lighting for HVAC systems resembles fluorescent lamps typically found in commercial office buildings. Both types of lamps have similar form and operate using identical electrochemical processes: an electric discharge through argon gas strikes mercury vapor to generate a photon with a wavelength of...
UV light comprises a segment of the electromagnetic spectrum between 400 and 100 nm, corresponding to photon energies from 3 to 124 eV. The UV segment has four sections, labeled UV-A (400 to 315 nm), UV-B (315 to 280 nm), very high energy and destructive...
If you’re a dental or other healthcare professional, customers no doubt appreciate your use of personal protective equipment (PPE), routine equipment sterilization and easy-to-clean fabrics and furniture. There’s a definite reassurance when a healthcare professional opens a fresh set of latex gloves or instruments. To...
Many factors can impact a building’s environmental performance and the consumption of energy, water and materials. Manufacturers of building systems design performance around a specific, optimal condition. Over time, these performance standards will deteriorate if nothing is done to preserve the original “as-built” condition. This...
ASHRAE recently released two position documents (links listed below) examining the health consequences of using filtration and air cleaning technologies in HVAC systems. Our own Dean Saputa is an active member of one of the committees responsible for this research (the ASHRAE Filtration and Air...
UV Resources offers EncapsuLamp™ technology. EncapsuLamp is a FEP encapsulation material (Fluorinated Ethylene Propylene) that hermetically seals UV-C lamps in case of breakage. Should an accident occur, broken glass and mercury will remain within the lamp protective shell protecting building occupants and facility managers....
We are in the midst of an HVAC revolution as the number of mechanical engineers specifying UV-C in all building types is mushrooming at historic levels.The ultraviolet-C (UV-C) wavelength (254nm) was promoted in the mid-1990s primarily to improve indoor air quality by preventing microbial buildup...
UV-C rips apart 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. In new HVAC/R systems where...
