Big Bag Filling
Docking Systems
Dec has developed a range of connecting systems meeting the different containment and GMP requirements. The choice for the right system strongly depends on the level of containment to be achieved.
For instance, the manually handled and simple inflatable seal system allows for a fast, economical and dust free connection whereas the DCS® Docking system provides high containment as it offers primary and secondary containment in addition to guaranteeing ISO 7 thus eliminating the need to install the emptying station in a clean room.
The selection of the appropriate docking system can be made as follows:
Dust free operation
Inflatable Seal System
​
Manually handled simple connecting system for fast, economical and dust free connection of FIBCs including a hinged holding ring.
​
Primary Containment: OEB 3-4
​SafeDock System
Patent pending SafeDock is a revolutionary system allowing for a very simplified and fast docking operation while guaranteeing a very high containment level. SafeDock consists of a docking tube with a CLS Continuous Liner side port for the removal of the liners and an automated cover on piston to fully seal the system. The big bag spout is sealed to the station by using a single-use ring which is removed with the remaining liner in a contained manner,
