Dépollution fait plus référence aux services d'urgence, de secours.

By analogy with the ECU (Electronic Control Unit) you can find in modern cars you would expect this PCU to be some kind of electronics controlling the depollution system, but in fact it's a reference to the whole of the depollution system.


What is the difference between commercial kitchen pollution control units?
JUNE 17, 2019 POLLUTION CONTROL SYSTEMS

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 abatement technology associated with them. The most common is an odor-neutralizing spray or activated carbon bed.

In addition, an exhaust fan that pulls the grease-laden vapors through the filtration and odor abatement components is included.

In order to understand how a Commercial Kitchen Pollution Control Unit (PCU) works it’s important to understand what is in the exhaust stream of a commercial cooking operation. There is grease particulate of varying sizes, ranging from vapor to large micron particulate, as well as water vapor and volatile organic compounds (VOC’s). The particulate distribution is also process-dependent. For example, if you were to cook 1000 lbs. of burgers on a charbroiler, you would expect to see 55 lbs. of total emissions (on average). Of that, about 62% is particulate and the balance vapor and VOC’s. If you cooked those same burgers on a griddle, you might see about 17 lbs. of total emissions (on average). Of that, about 65% would be particulate and the balance vapor and VOC’s. The ability of a PCU to remove those emissions is a function of the efficiency of the filtration.
