Big Bag Discharge
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 double tube 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
DoubleTube System with cover and manually operated clamp. This double ring and lever mechanism system allows for a fast and dust-free connection and discharge of big bags. Interchangeable inner tubes ensure flexibility, i.e. change of big bags.

SingleTube System with inflatable seal
In addition to the dust-free connection, the GMP design of this docking system allows for easy system cleaning including SIP if required. It comprises a single tube without internal parts. The BB is sealed to the tube by an inflatable seal which can be easily manipulated and secured in position providing very high tightness of the docking even for various liner sizes. The system can be cleaned by using a removable cover with a spray nozzle. Optionally an integrated ventilation ring allows to capture any dust during the removal of the big bags.

Primary Containment
SafeDock®
The patented SafeDock® connection system is revolutionary and allows for a very simplified and fast docking operation while guaranteeing very high containment levels. 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.
