New Approaches For Recirculating Systems in Kitchen Ventilation

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 […]

Ultraviolet Germicidal Irradiation UVGI

A Primer on UVGI (Ultraviolet Germicidal Irradiation)

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 […]

The difference between UV kitchen exhaust systems and corona discharge

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 […]
