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 […]

Capture and Containment, What does it mean?

A key function of any Kitchen Ventilation Canopy (Exhaust Hood), or Ventilated Ceiling, is its ability to catch the heat and fumes rising from the cooking appliances and to hold them until they can be drawn through the grease extractors and then into the exhaust system. This process is referred to as “Capture and Containment” […]

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 […]

System Neurology of a Kitchen Ventilation System

Ok, I’ll admit, I made up the fancy title to pique the interest of the engineering crowd.  It has a nice bio-medical ring to it.  However, I thought it was somewhat appropriate, given that this article will be discussing the connections and control sequences for commercial kitchen ventilation (CKV) systems. Several components make up a […]
