Schlieren Imaging

What is Schlieren Thermal Imaging in Commercial Kitchen Ventilation?

Wouldn’t it be nice to see the heat plume coming off of an appliance? Do you wish you could see if a hood is capturing all the convective heat? Isn’t there a better way to determine capture and containment than a smoke candle? Schlieren Thermal Imaging System provides a way to do all of these […]

What is the difference between commercial kitchen pollution control units?

Commercial Kitchen Pollution Control Units, also referred to as Scrubbers or Ecology units are systems that remove a high percentage of grease, vapor, and odors from the cooking process through a means of filtration. The devices fall into 2 major categories, media filter type and electrostatic precipitators (ESP). These systems have a form of odor […]

How heat sources differ in commercial kitchens than other commercial spaces

Mechanical engineers calculate cooling and heating loads for commercial spaces in order to size the ventilation systems. The type of space plays a key role in determining necessary ventilation requirements. Commercial kitchens are unique in they operate year round and cooling is almost always required, even during the colder winter months. This is due to […]

Why is a heat load based design important for kitchen hoods?

Establishing exhaust volumes for hoods had been an inexact science, primarily relying on U.L. values to establish exhaust rates. U.L. however clearly states that the minimum exhaust rates established during testing should not be used for design purposes since they were achieved in a laboratory environment. A greater exhaust might be required to provide proper […]
