Challenge:

The production of artificial fertilisers requires a lot of energy, especially the cooling of the entire process is a major challenge and must be managed with reliable technology. The plant in the Middle East with a production of 2.000 t/day of ammonia and 3.500 t/day of urea is one of the largest in the world. 
14 HETA Bernoulli filters (HSA) protect the gigantic titanium heat exchangers from contamination and ensure that the entire plant complex can carry out its reliable production "non-stop".

Filter Data: 

Design Code: ASME, Sec. X
Housing material: GFK
Design pressure: 7 bar
Filter rating: 3 mm
Flow rate: 4.413 m³/h

If you consider that a total of 14 filters each have a flow rate of 4.413m³/h, you arrive at the incredible amount of approx. 62.000 m³/h. This would mean that the Olympic swimming pool in Munich could be completely filled within about 23 minutes.
