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. |
