The revolutionary 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 technology and laminar flow technique, providing a high containment of < 1μg/m³ per 8 h TWA.
The station’s chamber is open to the side allowing easy bag introduction. A simple door needs to be closed only during WIP to prevent splashes. All WIP fluids can be drained from the chamber via the PTS Powder Transfer System* into the reactor, which also cleans the transfer hose and the PTS. The loaded hopper is then discharged via the PTS into the reactor.
Using the gloves the operator will move the bag into position on the powder charging bars above the hopper. The bag is then split and the powder emptied through the bars into the suction hopper. The empty bag is disposed through the adjacent continuous liner bag-out port.
On the opposite side elevation to the bag entry point is an exhaust plenum. A HEPA filtered exhaust is located on top of the plenum, connected to the manually dampered exhaust fan.
