Introduction
Airtec® A/S specializes in hygienic controlled air humidification systems, adhering to ISO 22000 HACCP standards to ensure food safety, particularly in the handling of water, which is considered a food product.

Specifications and Standards
The systems comply with ISO 22000 HACCP, ISO 9001 Quality, and ISO 14001 Environmental standards. These standards ensure comprehensive consideration of design, handling, and operation aspects.

Water as a Food Perspective
Humidification systems process raw water into fine particles for air humidity, necessitating hygienic design and operation to prevent health risks.

Risk Assessment and Legionella
Legionella pneumophila is a significant concern, thriving in temperatures between 20-50°C. The system design aims to prevent conditions conducive to bacterial growth, with a focus on minimizing stagnant water and maintaining low temperatures.

Traceability and Biological Soil
Traceability is crucial for risk management, allowing for error tracking and corrective actions. Biological soil, composed of organic material and microorganisms, can foster Legionella growth if not managed properly.

Raw Water Quality
Raw water must meet Danish drinking water standards, with a temperature not exceeding 15°C. Surface water supplies require extra attention due to higher bacterial access.

Testing and Hygienic Design
Airtec® systems undergo systematic testing and analysis by recognized laboratories to ensure hygienic design and operation. Critical control points are identified for hygiene handling, construction, operation, and service.

Operation and Maintenance
Regular service checks, water analysis, and monitoring are essential. Disinfection procedures are outlined for authorized personnel, with specific actions required if Legionella is detected.

Preventative Measures
Components are selected to prevent bacterial propagation, with automatic system rinsing every six hours. The high-pressure pump is frequency-controlled to avoid water bypass and reuse.

UV Treatment and Reverse Osmosis
UV treatment is an optional security measure, while reverse osmosis (RO) is recommended for fine filtration, removing nutrients and bacteria.

Hygiene Policy
Customers receive guidance on bacteriological aspects, with a recommendation for RO water treatment. Systems are designed for hygiene, but complete risk management combines this with RO treatment.

Conclusion
Airtec® systems are designed to operate safely with a focus on hygiene and risk management, particularly concerning Legionella. Comprehensive operation procedures and risk analyses are available upon request.
