Isolation and Laminar Flow Solution Enables Rapid Powder Charging with Room Air

Open charging through the manhole is no longer acceptable. A new development being successfully used by Dec clients worldwide is the DEC Isocharge — combining the open aspects of a laminar flow booth with a glove box isolator to enable the rapid and safe charging of powder products.

The DEC Isocharge is a low cost method of both dispensing and charging bags into reactors or receiving systems via the PTS (Powder Transfer System). The DEC Isocharge combines the advantages of isolation and laminar flow technology, providing high containment of <1μg/m3 per eight hours TWA.

The station’s chamber is open to the side allowing easy bag introduction. A simple door only needs to be closed during WIP to prevent splashes. All WIP fluids can be drained from the chamber via the PTS into the reactor, which also cleans the transfer hose and the PTS. Using the gloves, the operator will move the bag of powder into position on the charging bars above the integrated hopper. The bag is then split and the powder emptied through the bars. The empty bag is disposed through the adjacent continuous liner bag-out port. The operator then starts the PTS and charges the required amount of powder to the vessel.
