Recirculating systems or ductless hoods have typically had limited capacity on the type of appliances they serve. In addition, the connected power of the appliance was limited by what the device was tested under to obtain its U.L. 710B certification. Similar to ducted exhaust hoods, when recirculating systems are tested, the results of those tests […]
What is UVGI (Ultraviolet Germicidal Irradiation)? Ultraviolet Germicidal Irradiation (UVGI) is electromagnetic radiation that can destroy the ability of microorganisms to reproduce by causing photochemical changes in nucleic acids. Wavelengths in the UV-C range are especially damaging to cells because they are absorbed by nucleic acids. UV radiation affects the DNA/RNA of pathogens by breaking […]
COVID has brought constant change to commercial kitchens. A kitchen fire suppression system that’s flexible could be just what you need. The latest in fire suppression systems is already a staple in commercial kitchens around the world. Innovations make it an easy choice to meet code requirements, keep people and property safe with a dependable […]
It seems that every day brings a new Ultraviolet Germicidal Irradiation (UVGI) device that promises 99%+ efficiency on “killing” or neutralizing viruses. What does that efficiency level mean, and does it represent how effective it will be in all applications? These are all essential questions that we will attempt to explain in this blog. What […]
What are the best practices for ventilation system for restaurants and food service facilities re-opening after the pandemic?
With restaurants and other food service facilities fully opening, albeit with reduced capacity, key questions have arisen regarding best practices for ventilation systems. We questioned Dr. Andrey Livchak, Halton’s Global Technology Director, and member of ASHRAE for some answers. Q: What are your recommendations for starting up the HVAC system that may have been idle […]
What is the difference between exhaust hoods using Ultraviolet Light and Corona discharge ozone generators?
There is some confusion regarding the similarities and differences of kitchen exhaust hoods using ultraviolet light bulbs (UV-C) in the exhaust plenum and systems that are referred to as “corona discharge” that generate ozone. Ultraviolet Light or UV-C is a type of bulb that has a very high intensity that allows it to break down […]
What are UltraViolet lights in kitchen hoods used for and what outcome can I expect when using them?
Ultraviolet Lights or UV-C lights are a type of bulb that has a very high intensity that allows it to break down organic compounds. UV has been applied in a variety of sterilization and water treatment applications for decades. The wavelength varies by application. In the case kitchen exhaust systems, UV-C light is used to […]
