Many facility managers realize that they can increase HVAC capacity without replacing their chilled water or DX coil and avoid the significant replacement expense just by specifying UV-C. The 254mn germicidal wavelength removes and prevents microbial buildup and growth, which serves as an obstacle...
ASHRAE Research Project: UV-C Cleans Coils & Reduces Energy Use -- For years, UV-C users and manufactures have shared anecdotal experiences and case studies of successful installations of UV-C systems where the result was a clean cooling coil and reduced energy use. ASHRAE TC 2.9—the...
Biofilm is the greatest enemy of an efficient HVACR system. When biofilm gains a foothold in the coils of your air handler, a slew of operational and efficiency issues will lower performance and drive up costs. This is why it is important to have a...
Summer is finally here. Three months of warm, sunny days, ice cold beverages and microbial proliferation await you. That’s right. One negative side effect of the warm weather is humidity. As you know, HVAC systems perform their “cooling” operation by removing heat and moisture from...
Knowledge of UV-C goes back well over 100 years, having gone through various phases of development. Here are some pivotal points in the century-long history of the various applications of UV-C. ...
Over the past couple of decades, light energy in the Ultraviolet-C (UV-C) wavelength (253.7 nm) has been harnessed to kill and prevent the growth of, virtually all known microorganisms living HVAC/R components, such as cooling coils, plenum surfaces, drain pans and on air filters. The...
Brace yourselves. Flu season is upon us, and roughly 20 percent of the US population will experience flu-related symptoms, according to the National Institute of Allergy and Infectious Diseases. For many of us, especially the elderly and those suffering from medical conditions, these symptoms can...
According to the Center for Disease Control (CDC), more than 75 percent of all operations in the United States are performed outside hospitals in outpatient surgery centers (OSCs). Use of urgent care centers (UCCs) is also expected to rise as the population ages and health...
