New EU standard, EN 16282

The new EU standard – a step closer to sustainable commercial kitchens

EN 16282 - New EU standard for ventilation in commercial kitchens

The EN 16282 standard for ventilation in commercial kitchens was released in autumn 2017. This section aims to describe and discuss the new regulations and requirements for commercial air treatment methods. Before choosing your treatment method, take a minute to read this.

Smart demands for increased quality, safety and a greener world

EU’s new standard for equipment in commercial kitchens is long-awaited and well-produced. It covers everything from the hood to the point of discharge. . It took 14 years to finalize and aims to harmonize competition within the EU as well as setting quality requirements for functionality, safety and the environment.

Air purification technologies are described in part 8 where requirements are defined for equipment for treating kitchen exhaust air. The air treatment reduces fire hazards as well as odors. It is also a prerequisite for installing heat exchangers in the exhaust air stream enabling heat recovery.

The methodology is now spreading in Europe and will considerably reduce energy consumption and carbon dioxide emissions. A driving force is the Ecodesign Directive, which states that heat recovery used in real estates shall have a minimum thermal efficiency of 68% for battery-based heat exchangers and 73% for plate-/countercurrent heat exchangers as of January 1, 2018.

We have read the standard thoroughly and what follows is a summary of how some of the treatment technologies are affected.

The eight sections of the new EU standard EN 16282*

  • General requirements
  • Kitchen ventilation hoods
  • Kitchen ventilation ceilings
  • Air inlets and outlets
  • Air ducts
  • Aerosol separators
  • Fixed fire extinguishing systems
  • Installations for treatment of aerosols; requirements and testing

The Ecodesign Directive – a focus on energy usage

The Directive was adopted by the EU in 2005 and is aimed at reducing energy usage, and thereby greenhouse gas emissions by 20%.

General requirements for purification techniques

  • For technical safety reasons, components immersed in the air stream shall be designed to withstand a constant temperature of at least 60 °C. The exhaust air may, therefore, require cooling.
  • The installation must be easy to access for maintenance and cleaning purposes
  • Components exposed to UV-radiation or ozone should comprise of suitable materials
  • If ozone is emitted at ground level, concentrations must be below the applicable limit values
  • If ozone sensors are used, they shall be labelled “OZONE SENSOR” and have a unique traceable calibration certificate
  • Connections between the ozone generator and the kitchen exhaust duct must be visibly labelled “OZONE” every ten meters

New requirements for UV equipment (ozone treatment based on UV lamps)

The efficiency of a UV lamp is dependent on the temperature. For this reason, the maximum operating temperature specified by the manufacturer should not be exceeded. Installation of cooling measures may be required.

  • The UV equipment shall be installed in such a way that the entire polluted air flow is properly exposed to UV-radiation. If necessary, additional measures shall be taken to ensure this.
  • Safety equipment must be present to prevent the exposure of UV-radiation to skin and eyes
  • Flow/pressure sensors shall be incorporated as to prevent ozone from slipping into the kitchen
  • Hoods equipped with UV lamps shall carry a visible warning sign: “WARNING — UV radiation”
  • Inspection hatches on the exhaust duct shall carry a warning sign that reads: “WARNING — Ozone Treatment”

New requirements for ozone generators

For ozone generators fed with oxygen (for example, our high-performance RENA system), there are now several new smart requirements.

  • Installation, repair and maintenance shall be carried out by personnel educated by the manufacturer
  • The ozone generator shall only be in operation when the exhaust fan is running
  • Suitable equipment, such as flow and/or pressure sensor(s), shall ensure that ozone is not released into the building. If the system is equipped with a pressure sensor, it needs to be set up so that the ozone system is shut down should the differential pressure fall below 20 Pa
  • Inspection hatches on the exhaust duct shall carry a warning sign that reads: “WARNING — Ozone Treatment”

New requirement for air-fed ozone generators

In addition to the general requirements for commercial air treatment technologies and ozone generators, the standard specifies that oxygen-fed ozone generators shall be used for total exhaust airflows exceeding 2,500 m3/h. The reason for this is that air-fed ozone generators produce too high amounts of nitrogen oxides and nitric acid. The standard states:

“NOTE: To safe-guard against NOx and HNO3 build-up in the extract air, an oxygen-fed ozone generator will be used for a total extract flow exceeding 2500 m3/h.”

New requirements for photocatalytic air treatment (often called ozone-free UV light treatment)

  • F9- filter (ISO 16890, ePM1 80%+) shall be fitted prior to the photocatalytic system. The filter must be resistant to ozone and UV. The filter shall not be fitted in the kitchen hood/ceiling
  • For UV lamps, the maximum operating temperature specified by the manufacturer should not be exceeded
  • Hoods equipped with UV lamps shall carry a visible warning sign: “WARNING — UV radiation”
  • Inspection hatches on the exhaust duct shall carry a warning sign that reads: “WARNING — Ozone Treatment”

Note! As this technology contains both UV and ozone, the requirements for each treatment technology must also be taken into account.

Here are the requirements you can ask for 

 

   
  • Capacity to remove air-borne grease during high airflows
  • Minimum requirement for manual cleansing of ducts
  • Simple to install the distribution of the ozone ­­– even when the ducts are difficult to access
  • Capacity to treat air with high grease content
  • Low energy consumption
  • The ozone distribution should not interfere with the activities of the kitchen nor be aesthetically disturbing
  • Stable and consistent treatment capacity
  • Low operational costs
  • The ozone system should be able to be installed where it is out of the way of the activities being undertaken in the premises
  • Ability to prevent grease build-ups in ducts
  • Minimum lifespan of 20 years
  • Remote 24/7 monitoring to detect any interference
  • Does not disturb the ventilation balance
  • Lowest total cost of all purification technologies over time
  • The system should include an ozone sensor which turns off the system if ambient ozone levels exceed set threshold. The sensor shall be supplied with a uniquely traceable calibration certificate
  • No components installed in the air flow
  • The purification system should turn on/off when the ventilation system turns on/off
  • One single system should be able to treat several kitchens in, for example, a food court
  • High operational reliability
  • Stepless variable treatment capacity
  • For larger projects with high treatment requirements, several ozone systems should be able to be installed together
  • Minimum maintenance requirements
  • Easy adjustment of treatment capacity
  • Comply with requirements of EN 162882
  • Minimum service requirements
  • Easy to upgrade the system’s total capacity
