Drum Iris Technology
De Dietrich Process System offers the Patented Technology DIT® (Drum Iris Technology), which is an innovative and easy to use solution for a fast discharge. DIT® is the perfect alternative to the common docking methods based on bag in - bag out or inflatable gaskets. It offers greater ease of use and provides compatibility with drums of all diameters.
WORKING PRINCIPLE
The DIT® - Drum Iris Technology - is based on a double diaphragm valve interface, with full diameter opening and closing ends by means of a diaphragm: the iris.
The docking process consists of opening the external iris valve and then introducing the drum until it touches the internal iris still closed. After closing the external valve on the container body, the internal valve is
opened to introduce the top of the drum.
By this time, both iris valves can be squeezed on the drum body to seal the system to very low OEB 5 containment values.
The double elastic barrier minimizes the contact surface of the drum with the inner potentially contaminated atmosphere. The docking operations can be fully automatic without introducing the need of any kind of
consumables.
Furthermore, a negative or positive pressure difference (pressure cascade) between the double iris pass box and the adjacent environments is easy to achieve and maintain during all operations.
Advantages:
- Wide opening up to 700 mm
- GGreat versatility, allowing for drums of multiple diameters to be docked
- Easy cleaning and maintenance
- External body of the drum not in contact with the process
- Fully automated or manual docking system
Materials:
-
• FDA and/or ATEX (conductive) materials for the Iris
• Single use iris available
