Key Features of the ND 90 System, How ND 90 Is Optimized for Your Needs, Why Choose a UVC desinfection System?
What Is a UVC Disinfection System?
A UVC disinfection system uses ultraviolet C light to inactivate bacteria, viruses, and fungi by disrupting their DNA or RNA. This method is widely known as germicidal UV and is extremely effective for both air purification and surface sterilization.
If you’re new to this type of technology, read our guide on what UV is and how it works for a foundational understanding.
Unlike air filters or chemical cleaners, UVC light leaves no residue, requires no downtime for drying or ventilation, and avoids chemical exposure. When properly applied, it can reduce energy consumption compared to conventional methods, based on documented performance.
Where is ND 90 used?
The ND 90 UVC disinfection system is widely deployed in environments where microbial control is essential, such as:
- Cleanrooms in pharmaceutical and microelectronics industries
- Laboratories and R&D environments
- Food processing plants, especially in bottling and packaging lines
- Production areas with high hygiene standards
- Storage rooms and equipment zones
- Offices, canteens and dental clinics
ND 90 can be used for scheduled disinfection when rooms are unoccupied or integrated into cycles between shifts or processes.
Key Features of the ND 90 System
ND 90 is engineered with flexibility and performance in mind. Key features include:
- Fixed installation – Adaptable to different room types and disinfection strategies
- Food contact material approval – Suitable for environments that demand strict regulatory compliance and traceability.
- Aluminium or stainless-steel housing – For humid, dry, or hygienically critical settings
- Integrated safety – External monitoring for lamp function and replacement alerts
- Protection features – Includes shielding against glass splinters for operational safety
With its robust build and thoughtful design, ND 90 stands out as a long-lasting, professional-grade disinfection solution.
Models & Specifications
To accommodate different disinfection needs and spatial configurations, ND 90 is available in a range of models. where it’s possible to choose between painted aluminum stainless steel or hygiene housing. In addition, it is also available in a shorter version. The system can be adjusted for optimal UVC exposure.
| Model | Irradiation length | Total length |
| ND 90 ALU | 767 mm | 1002 mm |
| ND 90 STAINLESS | 767 mm | 1002 mm |
| ND 90 HYG | 767 mm | 1002 mm |
| ND 48 ALU | 360 mm | 660 mm |
| ND 48 STAINLESS | 360 mm | 660 mm |
| ND 48 HYG | 360 mm | 660 mm |
How ND 90 Is Optimized for Your Needs
Every environment is unique—so are its hygiene demands. That’s why ND 90 systems are customized to deliver the right UVC dose based on:
- Available exposure time – Short time slots may require stronger or more lamps
- Distance to surfaces or air volume – System layout is adjusted for optimal coverage
- Room configuration – Whether ceiling-mounted or wall-fixed.
- Task-specific needs – From intensive surface disinfection to continuous air sterilization
Our team at Natdis is happy to provide tailored advice and dimensioning support to ensure each system fits your exact needs.
Why Choose a UVC Disinfection System?
In contrast to conventional filters, a UVC disinfection system eliminates microorganisms rather than trapping them. ND 90 enables continuous air and surface disinfection in environments where both must be kept under strict control.
Key advantages:
- No chemical disinfectants required – UVC-based solution tested for hygiene-critical environments.
- Fast disinfection without waiting time
- Ideal for sensitive or closed environments
- Suitable for integration into GMP-compliant processes
Efficiency & safety
ND 90 delivers a high UVC dose in a short time and can be used at distances of up to 5 meters. Test results show up to 99% reduction of viruses such as CoV-2 when used correctly*. For safety reasons, we recommend using the system only in empty rooms, as UVC light is harmful to humans and animals.
*All performance claims are based on independent laboratory tests. Documentation on UVC dose and energy use available upon request.
