Exhaust air purification
oxytec can solve most exhaust air problems in an environmentally friendly way.
Innovative methods for exhaust air purification
When Oxytec was founded almost 20 years ago, UV-ozone technology for odor and grease reduction was still completely unknown. Fires caused by greasy extractor hoods were not uncommon.
Oxytec has made a significant contribution to establishing certified methods for exhaust air purification using UV-C and UV ozone technology. Today, this technology is state of the art.
UV ozone exhaust air purification
Cleansing storm
UV ozone disinfection uses UV light in combination with atmospheric oxygen to generate pure ozone. The process is inspired by nature: a cleansing thunderstorm works on the same principle. The fresh scent after ozone disinfection is similar to that after a thunderstorm, emphasizing the natural nature of air purification.
Air disinfection with pure oxygen
In conventional processes, ozone is generated using high voltage. This also produces nitrogen oxides, which in turn pollute the air we breathe. In oxytec systems, ozone is generated by UV light as an ozone generator—a process that does not produce any hazardous by-products such as nitrogen oxides.
Even the ozone disappears without leaving any residue because, as a highly reactive substance, it quickly forms compounds with other molecules, thereby neutralizing pollutants as desired.
The advantages
- Reduces odor and total C content in accordance with TA Luft
- Withstands humidity up to 100%
- Tolerates load fluctuations
- Works as an on/off system and without preheating
- Energy-saving
Exhaust air purification systems with UV ozone
Clean Exhaust Air – Air treatment based on UV and ozone
This exhaust air system is designed for exhaust air purification in industrial applications. Air purification takes place in three steps:
- Breakdown of long-chain compounds by UV light
- Formation of ozone and hydroxyl radicals and their decay products
- Reaction of ozone with the broken down compounds
The system effectively reduces VOCs/total C, formaldehyde, H2S, odors, and fats in industrial exhaust air and complies with all regulatory requirements in accordance with TA Luft (total C, formaldehyde, aromatics, mercaptans, odor limits).
The system is easy to install, is also suitable for placement on the roof, has low CO₂ emissions, and very low energy consumption.
Clean Fryer Air – compact exhaust air purification system for greasy exhaust air
The compact and lightweight Clean Fryer Air (CFA) exhaust air purification system is designed for exhaust air purification in the food industry, especially for processes involving fatty, organically contaminated, and odorous exhaust air.
This system creates pleasant working conditions by significantly improving the indoor climate and meets all regulatory requirements (total C, formaldehyde, aromatics, odor limits). The CFA is the ideal solution for frying and deep-frying lines and is also suitable for other odor-intensive processes.
UV-C disinfection of the air
The sun as a role model
As early as 1877, English researchers discovered that microorganisms do not continue to multiply when exposed to sunlight. Later research revealed that this effect is caused by light with a specific wavelength, now known as UV-C or ultraviolet radiation.
Comprehensive protection against germs
UV-C air disinfection is effective against all airborne microorganisms such as bacteria, viruses, and mold. UV-C disinfection replaces thermal processes, avoids the use of chemicals, leaves no harmful substances behind, and is therefore particularly environmentally friendly.
UV-C air purification provides valuable services in food production because it reduces the risk of contamination and helps to avoid the use of preservatives. UV-C air purification is particularly suitable for rooms where people or animals are permanently present.
The advantages
- Improves the appearance, shelf life, and quality of food
- Reduces germ contamination during production
- Prevents the development of germ resistance
- Prevents cross-contamination
- Eliminates the need for chemicals
UV-C systems for air disinfection
UV IB – for installation in HVAC systems
The UV-IB sterilizes the air using UV-C technology. It has a ballast integrated into the frame. Germs, viruses, yeasts, and mold spores, which often settle in air conditioning and ventilation systems and are distributed into rooms with the air flow, are effectively eliminated.
Plasma exhaust air purification
Solar heat in the nano range
Plasma is a high-energy state of matter. 99 percent of the universe consists of plasma. The sun, for example, is a gigantic ball of plasma. Air purifiers using this technology have proven themselves in the purification and odor reduction of commercial and private kitchen exhaust air as well as industrial exhaust air.
Safely neutralize fats, viruses, and pollutants in exhaust air
In plasma air purification, the air is converted into the energetic state of plasma by controlled voltage. Viruses, bacteria, and germs are destroyed in the process. At the same time, activated oxygen (O³) is produced in the plasma, which also reacts with the pollutants in the air and binds them. The air becomes harmless and odor-free in a fraction of a second, and fatty components are broken down.
The advantages
- Reliably eliminates unpleasant odors
- Enables downstream heat recovery without additional effort
- Enables exhaust air to be fed into areas where people are present
- Turns exhaust air purification into a ventilation unit
scrubber
Simply wash out the particles
Exhaust air from smokehouses, laboratories, or animal stables often contains solid components such as ammonia and odor-carrying particles. Oxytec scrubbers remove these particles, reduce the exhaust air temperature, and enrich the air with moisture. In this way, they also help downstream UV systems to achieve greater efficiency.
The advantages
- Filters coarse particles and non-oxidizable substances
- Separates up to 95% of soot particles and ammonia
- Reduces odors by approx. 30%
- Reduces exhaust air temperature by approx. 50%
Scrubber for reducing VOCs, ammonia, and formaldehyde
Scrubber systems are used for pre-cleaning contaminated exhaust air and also reduce the exhaust air temperature. They are suitable for smoke-contaminated air and for washing out water-soluble substances such as ammonia or formaldehyde.
Smoke scrubber for cleaning smoke exhaust air
This smoke scrubber system uses an automated exhaust air scrubber plus a downstream UV ozone system to clean the heavily tar-laden smoke exhaust air from manufacturing processes in the food industry (smokehouses) and eliminates the high odor emissions.
Clean Washer Air
This exhaust air scrubber system effectively removes water-soluble and odor-carrying particles from the exhaust air. It has proven particularly effective for ammonium-contaminated exhaust air from laboratories, animal stables, slaughterhouses, and animal processing facilities. Pollutants are effectively separated from the exhaust air.
The washing liquid is sprayed into the air stream, achieving the highest possible washout rates for toxic gases and odorous substances.
The washed-out substances are concentrated and separated via a sump. More than 99% of chlorine gas, ammonia, and hydrochloric acid vapors are removed.
