The service program for the food and beverage industry

The first step is a comprehensive check of the actual condition of your ventilation system and its specific components, from the supply air duct to the exhaust air duct. Particular emphasis is placed on determining the total number of germs or colonies in the air; this mostly concerns microorganisms. Product contamination can be reduced to a minimum with regular hygiene inspections and airborne germ collections in accordance with VDI 6022-2018. The air filters used must be certified for food and comply with mandatory industry standards.

Meaningful and audit-compliant reports are generated for all routine inspections or complete service and maintenance programs for ventilation systems (air handling units) and clean rooms, which form part of an individual Viledon FilterCair service contract. Specific inspections and analyses are individually adapted to the needs of your production process.

The air itself can be a source of contamination. Depending on the expected hygiene risk of the production facility – the EHEDG zone concept is a suitable starting point – the ventilation concept needs to be reviewed and, if necessary, optimized. As well as filter quality, the selection of the appropriate filter efficiency for each filter stage plays an important role. In addition, to reduce the growth of microorganisms, the air quality must be permanently regulated and controlled with regard to temperature and humidity.

We will be pleased to examine your system in accordance with VDI 6022:2018 and carry out an initial hygiene inspection or repeat inspection with airborne germ measurements. All our service specialists are masters or technicians and are qualified according to VDI 6022 Category A. These inspections of the hygiene condition of the ventilation system / air handling units can form part of a Viledon FilterCair service contract agreed with you.

When selecting filters, it is crucial that they meet the highest food safety standards and have the required filter classification according to ISO 16890 and EHEDG Doc. 47 recommendations. Filter quality can be measured on the basis of whether filters are microbiologically inactive and suitable for operation at up to 100% relative humidity. They should also be resistant to mechanical stress. Damaged or incorrectly installed air filters represent a weak point for contamination. Depending on whether filters come into direct or indirect contact with food, they have to comply with specific regulations or strict guidelines. Only if the filter quality is certified can you be sure that you are using food-grade air filters.

The EHEDG zone concept divides the various areas of a production facility into zones according to the respective hygiene requirements: H (high hygiene risk), M (medium hygiene risk) and B (basic hygiene risk). We use this method of analysis as a basis for recommending a coordinated, multi-stage filter concept with food-compatible air filters of various filter classes and types.

We can carry out an energy analysis within the framework of a plant inspection. In the process, we examine individual components for their functionality. An energy analysis precisely measures the current energy consumption. In a more detailed inspection, our technical experts check the complete ventilation system from a cooling capacity > 12 kW according to § 12 EnEv.

We use these values as the basis for creating individual recommendations and optimization proposals to effectively reduce energy consumption over the long term.

Within the scope of a flow and overpressure analysis, we are able to visualize the airflow conditions at production and workplaces. This involves a precise measurement of the overpressure, air exchange rates, air speeds and the entire ventilation system in the clean room. Once this process has been completed, you will receive recommendations for optimizing your food factory design. We will also be happy to offer you customized engineering solutions for a plant conversion project.

The first step is to carry out an on-site analysis. By measuring occupational exposure limits or emission values, we can determine the composition of the air and the associated odors. Based on the results of this analysis, we develop filter or even complete exhaust air concepts that optimize the exhaust air. This may involve additional filter stages or the installation of activated carbon filters, for example. These and other optimizations can form part of the solution. We will be happy to support you wherever clean air for people and machines is required.
