Exhaust air purification in the smokehouse – safely controlling smoke, odors and pollutants

The combination of:

• Grease fog,
• smoke particles,
• phenols, aldehydes and VOCs,
• as well as intense, persistent odorous substances
  make exhaust air purification in smokehouses particularly challenging.
  These substances are not only unpleasant smelling, but can also be corrosive, harmful to filters and harmful to health.

The system uses:

• UV-C radiation to break down organic molecules
• Ozone oxidation to neutralize smoke components, odour molecules and VOCs
  The advantage: No combustion, no residues, no thermal pollution of the air.

Yes – especially fish odors (e.g. e.g. from salmon, mackerel, trout) contain sulfur and protein molecules that are extremely odor-intensive.

Clean Air has been specially developed to effectively treat such tough cases.

In practice, odor reduction is > 90 %, in some cases significantly higher – depending on pre-separation and air flow.

No – thanks to the modular design with:

• mechanical pre-separation (metal filter, coalescence filter)
• and, if necessary, automatic filter monitoring
  UV chambers and reactor surfaces remain protected.
  Maintenance can be planned and is adapted to the process.

Yes – the systems are designed for hot, humid, greasy exhaust air.

Maximum extract air temperature: approx. 80 °C Continuous operation

At higher temperatures, preconditioning with heat exchanger can be used.

UV lamps: Change every 8,000-10,000 operating hours

Filter cleaning: depending on grease load, usually monthly or quarterly

Optional: automatic contamination detection and remote monitoring
Maintenance is much easier than with a thermal oxidizer (TNV).

Clean Air Systems:

• work without an open flame
• require no gas, no combustion
• contain ignition source-free UV modules
  They therefore meet the highest safety requirements, even in greasy environments.

Yes – Clean Air fulfilled:

• the requirements of TA Luft 2021 (VOCs, organic emissions)
• the requirements of the GIRL (Odor Immission Directive)
• optionally also requirements from the BImSchG / 31st BImSchV
  We provide the necessary technical documentation, proof of emissions and measurement documents

Yes – the system is:

• modular,
• space-saving,
• can be integrated into exhaust air ducts, shafts or roofs
  Retrofitting is generally possible, even in difficult building structures or during operation.
