Clean air starts with a hygienic ventilation system
Ventilation and air handling systems play a vital role in creating a safe and healthy environment. In hospitals, laboratories, pharmaceutical production facilities and other critical environments, contamination and microbiological growth can lead to significant risks.
A hygiene inspection provides insight into the hygienic condition of your installation and identifies issues that may affect indoor air quality.
Inspections in accordance with VDI 6022
Normec performs hygiene inspections in accordance with the VDI 6022 guidelines. During the inspection, our specialists assess both the technical and microbiological aspects that influence the safety and performance of the system.
The inspection includes:
- Verification of the correct installation and operation of system components
- Identification of hygiene-related risks
- Assessment of the visual cleanliness of the system
- Microbiological evaluation of supply air and reference air
- Analysis of moulds and yeasts
- Testing of recirculating water in humidification systems
- Microbiological surface testing
Comprehensive reporting with practical recommendations
After the inspection, you receive a detailed report summarising all findings. We identify potential risks and provide practical recommendations for improvement.
This means you can:
- Gain insight into the hygienic condition of your ventilation system
- Prevent air quality issues and microbiological contamination
- Reduce the risk of mould growth and bacterial contamination
- Receive a clear report with practical recommendations
- Support a safe environment for employees, patients and visitors
Accredited laboratory analysis
All microbiological samples are analysed in Normec's own DAkkS-accredited microbiology laboratory, ensuring reliable results and short turnaround times.
We analyse, among others:
- Total viable count (TVC)
- Legionella
- Pseudomonas species
- Moulds
- Yeasts
By combining on-site inspection with accredited laboratory analysis, we provide a comprehensive assessment of the microbiological quality of your ventilation system.
Supporting health, safety and compliance
A well-maintained ventilation and air handling system contributes to a healthy indoor environment and helps identify potential risks at an early stage. Regular hygiene inspections allow issues to be addressed before they affect people, processes or products.
