Ammonia > 90 % o Evaluation range: ++ / + / o / - / — (o = standard) Form hexagonal disc with starformed ribs on both sides Material recycled plastic, 100 % polypropylene Dimensions diameter: 228 mm, heigth: 80 mm I. Scope The FokusTest included measuring of the emission reduction of odour and ammonia under laboratory conditions. The examinations (see test conditions in table 1) were carried out by two measuring laboratories on liquid pig manure independently of each other. To evaluate the emission reduction the efficiency was obtained by measuring uncovered...

Concerning the practical use of the Hexa-Cover cover system, the following can be concluded to determine the emission flow value: Assumption: - Flow value = 10 m3/m2h; - container diameter = 15 m; Example 1: Summer 18°C By a reduction of the odour concentration from 10.000 GE/m3 to 700 GE/m3 under the above assumptions a volume flow value of 1,2 MGE/h will be evident. Example 2: average annual temperature 12°C By a reduction of the odour concentration from 2.000 GE/m3 to 200 GE/m3 under the above assumptions a volume flow value of 0,35 MGE/h will be evident. Odour concentration (GE/m3)...

The FokusTest consisted of technical measurings of odour and ammonia emission reductions from liquid pig manure under laboratory conditions. The cover system was not tested in practice. On basis of the available results the Hexa-Cover cover system, in reference to the test criteria „Odour and ammonia emission reduction", fulfils the demands (evaluation (o) or better) in order to achieve the DLG FokusTest label. Other criteria have not been tested. Testing German Agricultural Society Test Center Technology & Farm Inputs Max-Eyth-Weg 1 D-64823 GroS-Umstadt Special tests - Odour emission...
