TU91 PE DK - Tube filling machine
for low-viscosity products in the pharmaceutical sector (long-neck tube / microclysters)

The TU91 PE DK is a specialized tube filling machine for processing low-viscosity and alcoholic products in long-neck tubes or microclysters. The machine was developed specifically for requirements where high speeds and precise dosing of liquid media are paramount.

The machine achieves an output of approx. 90 tubes per minute. Despite the high cycle rate, a filling accuracy of ± 0.5% is guaranteed. A mechanism optimized for low-viscosity filling material ensures that the medium does not slosh even during fast movement sequences, which guarantees clean sealing processes.

GMP, hygiene and cleaning speed

Optional ATEX conformity makes the system suitable for the safe filling of alcoholic and highly flammable products. GMP- and FDA-compliant data integrity in accordance with 21 CFR Part 11 ensures the necessary legal certainty in the documentation. This safety package is supplemented by integrated quick-cleaning technology, which not only guarantees maximum process hygiene, but also effectively minimizes set-up times and downtimes.

The TU91 PE DK is controlled via a 17″ touch display with integrated user and recipe management. The system can also communicate seamlessly with downstream machines.

Technical highlights

Drive & mechanics

  • Loi Liquide technology: Cam-controlled 12-station rotary indexing table with movement sequences optimized for low-viscosity products to prevent sloshing effects at up to 90 tubes/min.
  • Gentle handling: soft-touch guiding and specialized tube holders with integrated ejector protect sensitive surfaces.
  • Durability: Cam-controlled work stations and automatic central lubrication (H1 fluid grease) ensure low-wear continuous operation.

Dosing accuracy & quality assurance

  • Precision filling: Filling accuracy of better than ± 0.5% (standard deviation for very small quantities approx. 0.01 g).
  • Integrated sensor technology: double pharmaceutical code scanning for alignment and code checking as well as air bubble detection in the product.
  • Discharge: Highly dynamic, separate good/bad discharge with torsion-free discharge via hose coils.

Hygiene & maintenance

  • Minimal contact surfaces: Only 6 parts in contact with the product per pump (approx. 325 cm² total surface area) for extremely short cleaning times.
  • Fast service: Tool-free adjustment of the feeders and quick-change pump units (autoclavable).
  • GMP design: Line-clearance-optimized machine design with transparent covers for maximum process visibility.

Control & integration

  • Compliance: Data integrity in accordance with 21 CFR Part 11 including audit trail, message logger and automated PDF batch report.
  • Smart Stop: Intelligent communication with downstream packaging machines to prevent product loss during line stops.
  • Flexibility: Scalable filling volumes from 0.5 to 300 ml and optional design for metal tube processing.
