UV-C technology for clean air despite minimal air exchange
Modern buildings are energy efficient—but often poorly ventilated. Where open windows used to provide fresh air, minimized air exchange now regulates consumption. But too little air exchange means that germs, aerosols, and odors remain in the room—a risk to health, well-being, and product quality.
Oxytec’s UV-C technology strikes a balance between energy efficiency and hygienic air supply.
What would you like to know?
Simply put your question to our AI. They will answer you individually:
Typical problem areas with reduced air exchange
| Application | Challenge | Risk |
|---|---|---|
| Energy-efficient houses, passive houses | Very low air exchange rates | Accumulation of germs, CO₂, VOCs |
| Classrooms, meeting rooms | Many people in a confined space | High aerosol and germ contamination |
| Food processing | Room air should remain hygienic – despite recirculated air | Contamination of products or surfaces |
| Cooling and storage rooms | Air exchange reduced for energy reasons | Germ contamination, odor formation |
Why use Oxytec with minimal air exchange?
- Germ reduction without increasing the air exchange rate
- Energy savings are maintained – hygiene is improved nonetheless
- Can be retrofitted into existing air ducts or recirculation units
- Ideal for rooms with air quality requirements and cost-saving constraints
Legal requirements
VDI 6022 – Hygiene requirements for air handling units
- Air exchange must be compensated for by hygiene measures if energy consumption is reduced
- UV-C is recognized as an effective measure for germ control
Workplace guidelines (ASR A3.6)
- Requirements for air quality and CO₂ concentration
- Technical alternatives are permissible if the room air remains hygienic
Energy efficient—but hygienic, please.

FAQ – Frequently Asked Questions
How can I ensure hygienically safe indoor air despite reduced air exchange?
With oxytec’s UV-C recirculation systems, the air in circulation is sterilized without the need for additional outside air.
This maintains energy efficiency while ensuring that the indoor air is free of germs, viruses, spores, and bioaerosols.
Does the use of UV-C technology comply with current hygiene regulations?
Yes – our systems meet the requirements of:
- VDI 6022 (hygiene requirements for air handling units)
- DIN EN 60335-2-65 (Safety of ventilation and air-conditioning units)
- ASR A3.6 (Air quality in workspaces)
UV-C is recognized as an effective technology for air disinfection – even with reduced air exchange.
Can I retrofit UV-C technology into existing ventilation or recirculation systems?
Yes. Our modular systems can be integrated directly into:
- HVAC systems
- Recirculation units
- Split units
- Cooling and storage rooms
– or used as a free-standing recirculation unit.
How much maintenance do UV-C systems require?
Minimal. The UV-C lamps have a service life of up to 9,000 hours.
Maintenance only involves:
- Annual lamp replacement
- visual inspection and simple cleaning
- Optional operating hours counter for planning
No moving parts, no filter replacement – low maintenance and predictable.
Am I really saving energy by using UV-C instead of more fresh air?
Yes—because more fresh air means additional heating or cooling losses.
The UV-C solution enables germ-free recirculated air without the need to supply cold or warm outside air.
This reduces operating costs and keeps the indoor climate stable.
Is there a solution for smaller rooms without central ventilation?
Yes. We offer compact floor-standing units with UV-C for:
- Canteens, waiting rooms, offices
- Recreation rooms in production facilities
- Cooling areas with foot traffic
These devices only require a power outlet and operate quietly and ozone-free.
How can I ensure that the system is correctly designed?
Our engineers calculate the appropriate UV-C dose, air exchange rate, and placement for each application.
You receive a technically tailored solution with documentation that fits into your existing concept—whether it’s a new design or a retrofit.
