CLS Continuous Liner System

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.

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 connected to the filling line.

It includes an automatic back-flushing system by compressed gas (air or nitrogen) and a connection to an extraction system. The system is 100% cleanable by back-flushing the membrane with a cleaning solution and through an integrated spray nozzle.

The inflate and deflate function inerts the bag and controls the pressure inside the system. A pressure sensor can be added in line for automated pressure control during the filling process.

The vent filter can be supplied in various sizes and materials to suit specific process requirements.

Vent File

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.
