Sterile workspaces – protection for people and products

oxytec systems for hygienic air in food-related production areas

In sensitive production areas—whether in the food, pharmaceutical, or packaging industry—the quality of the indoor air is crucial for product safety and the health protection of employees. Pathogens and contaminants enter processes, systems, and packaging lines unnoticed via aerosols, droplets, dust, and airborne germs.

oxytec systems for germ-free workspaces provide an effective barrier against airborne risks. Continuous air disinfection, germ-free circulation, and controlled air flow create hygienically safe conditions for employees and sensitive products.

Typical sources of germs in the workplace

Source Air pollution Special features
Employees Aerosols (speaking, breathing, coughing), skin particles Biological contamination, mobile, uncontrolled
Goods entry/logistics Dust, spores, packaging abrasion Combination of microorganisms & mechanical particles
Room air & air conditioning Recirculated air germs, viruses, condensate germs Often underestimated, difficult to control
Machines/surfaces Abrasion, dripping, unwanted air turbulence Locally limited, but product-specific effective

Why are sterile workspaces so important?

Microbiological contaminants can spread unnoticed in the air.

Product protection against recontamination, biofilm, spoilage, and complaints.

Employee protection against airborne pathogens such as influenza, noroviruses, or SARS-CoV-2.

IFS/BRC/HACCP certifications require microbiological control of the air.

High product liability risks in the event of detectable contamination.

Legal requirements

  • IFS Food / BRC / FSSC 22000: Air quality as CCP or oPRP
  • DIN EN ISO 14644-1: Cleanroom classes and air purity
  • HACCP concept: Risk analysis and hygiene control
  • Occupational Safety and Health Act & Biological Agents Ordinance (airborne pathogens)

We support you with measurement reports, risk assessments, and plant validation.

FAQ – Frequently Asked Questions

Which germs are reduced in the air by Oxytec systems?

Our systems are effective against:

  • Bacteria (e.g., listeria, salmonella)
  • Viruses (e.g., noroviruses, influenza, SARS-CoV-2)
  • Mold spores and yeasts
  • Pollen, skin particles, and dust mites

Depending on the room concept, the reduction is typically 90–99.9% (2–4 log levels), verifiable by microbiological air measurement.

How does air disinfection with UV-C work?

The system uses:

  • UV-C radiation at 254 nm, which destroys the DNA and RNA of microorganisms
  • An integrated fan guides the air through the sterilization chamber
  • No ozone formation, no chemical residues
  • The process is continuous and safe even when people are present

Does the system have a negative impact on air quality or indoor climate?

No – Clean Air systems operate:

  • without changing the temperature
  • quietly and unobtrusively in continuous operation
  • chemical-free, without odors or residues

On the contrary, they improve the sensory air quality (less “production odor,” less air heaviness).

How is the effect proven or documented?

We offer:

  • microbiological comparative measurements (air samplers)
  • log-level reduction verification with and without system operation
  • Audit-ready validation documents for IFS/BRC/FSSC
  • Support with HACCP risk assessment and CCP documentation

Can the system be integrated into existing rooms?

Yes – Clean Fryer Air systems are:

  • modular and retrofittable
  • available as ceiling or wall units, floor-standing modules, or duct-mounted units
  • suitable for use in rooms with personnel, machines, or direct product contact
  • can be integrated into existing air conditioning systems or ventilation zones

How large is the treated area per device?

Depending on the model and room structure:

  • Rooms from 20 to 150 m² per individual unit
  • Larger areas via system combination or air zone control
  • Design is customized according to room height, air movement, and hygiene requirements

How often do the UV lamps need to be replaced?

The UV-C lamps have a service life of:

  • approx. 8,000–10,000 operating hours
  • Replacement usually once a year (continuous operation)
  • Maintenance can be carried out by your own staff or as part of a service contract

How does the system contribute to the protection of employees?

Airborne pathogens (e.g., influenza, COVID, noroviruses) are continuously reduced

Particularly useful in confined areas, transfer zones, or packaging rooms

The risk of infection is reduced, and absences due to illness can be reduced

Contributes to occupational safety and occupational health management

Do the systems meet the requirements of IFS / BRC / HACCP?

Yes – Oxytec Clean Fryer Air systems are:

  • validatable in terms of their microbiological effect
  • suitable for risk processes with CCP or oPRP classification
  • compliant with the hygiene objectives of IFS Food, BRC Global Standard, FSSC 22000
  • audit-ready documented with data sheets, proof of effectiveness, and maintenance plans
