Hygienic design
The surface roughness of the wetted parts made of stain-less steel are executed according to EHEDG Doc.8 and ASME BPE SF3.
In case of choosing the additional feature HY, we guarantee the following surface roughness values:
Diaphragm foil: Ra ≤ 0.38 µm
Laser welds: Ra ≤ 0.76 µm
Turned parts: Ra ≤ 0.76 µm
Further versions of hygienic design upon request.
