CLS Continuous Liner System

Closing devices, liner specifications and accessories

Dec can provide various closure devices depending on the level of containment to be achieved.

Standard Clip System up to OEB 3*

  • Closure tool device with specially designed cable tie system

  • Strong closure for different sizes of liner

  • No sharp edge

  • Simple and fast operation

SafeSeal - High Containment Clip System up to OEB 4*

The SafeSeal closure is a new PA double crimp system with an axial closing mechanism and includes a pressing and cutting tool.

 

The SafeSeal closure is pulled manually over the bag and pressed together with special closing pliers. The crimp is then separated with a cutting tool. In addition, the crimp can be opened by cutting the outer closing mechanism with the cutting tool. That way, the foil can't be damaged.

 

  • Simple and safe operation

  • Closure system kit consisting of the SafeSeal closure, a pressing and a cutting tool

  • High level of containment (<1 µg/m3)

* Depending on powder characteristics and operational procedure

Liner Specifications

The liner can be supplied pre-folded in various sizes, produced in an ISO class environment and delivered in a PE  bag. Fold height and length depend on the foil thickness.

Vent Filter / Inflate and Deflate Function

 

In order to prevent a pressure increase in the system when powder is charged into bags, the system must be able to breathe in order to evacuate the gas brought in.

 

Especially when precise filling is relevant, avoiding any pressure in the bag is very important as it could influence the scale.

When handling toxic, irritant or dust explosive powders, it is also imperative to avoid dust propagation into extraction lines which could lead to cleaning issues, operator exposure risks or even possible blockages due to powder accumulation in downstream equipment.

Dec's highly efficient, automated Vent Filter based on PTS filtration technology which can be connec...

 

Sampling

It is often mandatory to take samples during the filling procedure at different intervals.

​When considering a contained and GMP compliant filling system, it is not possible to reopen the packaging to take the samples manually afterwards.

 

Dec provides fully contained solutions to take samples either directly out of the filling system with MPTS or with a mechanical sampling device installed in the charging tube.

 

The sampling system is fully automated and synchronized with the filling operation able to draw samples at given intervals.   The bottle is placed in a safety cabinet or a glove box for safe removal.

Safety Cabinet

 

For additional containment around the CLS for higher operator safety in case of liner failures, Dec can provide a  safety cabinet around the filling station.

The cabinet includes an access door for the drum installation and removal and gloves to prepare the liner.

 

The system can be cleaned with a spray gun and comprises a drainage point.

For even higher containment, the cabinet can be equipped with a pass box on the side to enter and remove the drums. 

Welding Maschine

 

Instead of a clips system, a welding machine can be used for the sealing of the bags.

 

The welding system can be integrated in the support frame.

 

This arrangement enables welding and cutting of the liners in a single operation.

 

  • Various length depending on liner size

  • ATEX zone 1 /21

  • OEB 4 containment

Bellows

 

Specific weight compensator to prevent any scale influence.

 

Triclamp connections are moulded to the bellows guaranteeing a tight connection and efficient cleaning.

 

 

  • Size DN 50, 100, 150, 200

  • Material : EPDM, Viton

  • Antistatic, FDA
