Hygienic Certificate for AHU

Air Handling Unit Hygiene Certification aims to ensure that the air handling units contain hygienic features that guarantee maximum air quality and ensure the continuity of applications.
With this certification, the quality of the materials used in air handling units, the selected components and components of the housing level by controlling the maintenance level of the plant’s hygienic expectations are guaranteed.
Air quality control in commercial buildings, schools, hospitals, clean rooms and all buildings plays a key role in today’s building design. Air handling units are at the forefront of the air movement in the buildings and are the basic element in providing the best climate solution.

There are 3 different independent institutions which will be Eurovent, TÜV SÜD and TÜV NORD which can be obtained for air handling units.

Eurovent Hygienic Certificate

Today, professionals face new challenges and precise calculations based on performance data to meet the carbon footprint reduction goals and to meet the constraints imposed by building codes.
While several environmental labels advocate good air quality for commercial buildings, the realities on the market are very different. The present Hygienic Standards are in fact limited to the hospitals and pharmaceutical environments to which they are applied. This is why ECC has developed a hygienic option certificate for air handling units. The approval process included four groups of experts: end-user representatives, manufacturers, technical and scientific experts, and national authorities.
This certification program includes 60 requirements for the hygiene standard. These requirements are; production, transportation, materials (conforming to European standards), maintenance, body performance, air purification (arrangement and performance of components – filters, batteries, heat recovery systems, fans, humidifiers, dehumidifiers and silencers). Compared to the existing hygienic certification, the amount of each requirement is defined or clearly defined in the new standard. Annual audits document the ability of a manufacturer to produce hygienic power plants. After being certified with a hygienic option, the air handling unit will be declared suitable for the different applications defined by its classification: 

The Hygienic option is a certification by range proposing 3 levels of certification representing by stars​

All the requirements are listed in the RS, they are related to the following topics:
