T-Rack™ Configuration

The datasheet provides detailed tables for T-Rack™ unit configurations, including single-sided and double-sided connections to manifolds, with 2-row and 4-row arrangements. These tables specify the number of modules, T-Rack™ unit part number, rack length (excluding central header manifold), and total membrane area.

See the official PDF for exact tabulated values.

General Information

• Avoid any abrupt pressure variations during start-up, operation, shutdown, cleaning or other sequences to prevent possible membrane damage. The maximum pressure change allowable is 0.5 bar/s.
• For assembly, refer to the latest version of the DuPont™ IntegraTec™ Pressurized UF In-Out P Series Assembly Instructions for T-Rack™ Manual (Form No. 45-D02230-en).
• If operating limits and guidelines given in this bulletin are not strictly followed, any warranty will be null and void.
• To control biological growth during extended system shutdowns, a storage solution must be introduced into the membrane modules. For detailed information, see the DuPont™ IntegraTec™ Pressurized UF Out-In Module Preservation Instruction Manual (Form No. 45-D02946-en).

Regulatory Note:

• Certified drinking water modules require specific conditioning procedures prior to producing potable water. For operating parameters, please refer to the DuPont™ IntegraTec™ Pressurized UF In-Out P Series Process and Design Guidelines (Form No. 45-D02234-en).
• Drinking water modules may be subjected to additional regulatory restrictions in some countries. Please check local regulatory guidelines and application status before use.
• Flushing needs to be done according to the DuPont™ IntegraTec™ Pressurized UF Out-In Module Rinsing Procedure (Form No. 45-D02947-en).
