Mechanical / Hydraulic
| Model | Element Weight (kg (lb)) | Dim. A (mm (inches)) | Dim. B (mm (inches)) | Dim. C (mm (inches)) | Permeate Tube |
|---|---|---|---|---|---|
| Oltremare BR1HR-4611E | 5 (11) | 287.5 (11.32) | 116.8 (4.6) | 19.1 (0.75) | Male |
| Oltremare LOW1– 4611E | 5 (11) | 287.5 (11.32) | 116.8 (4.6) | 19.1 (0.75) | Male |
For male elements, "C" is the outer diameter, and they have a protruding permeate tube.
Important Information
- Start-up: Elements should be flushed for 30 minutes at low pressure, discarding permeate, prior to operation.
- Cleaning: Periodic cleaning is required to ensure proper operation and prevent membrane damage. Refer to the Membrane Cleaning Guide.
- Storage: Elements must be stored appropriately to ensure proper operation and prevent membrane damage. Refer to Element Storage Guides.
