Hygienic design
| The surface roughness of the wetted parts made of stainless 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. |
Temperature error
| In order to optimise the system we provide a detailed error calculation upon request . |
Weight
| For process connection Form B (D = 31): ca. 0.3 kg Form F (D = 50): ca. 0.6 kg Form N (D = 68): ca. 0.8 kg |
