Isocharge

High containment bag handling and process charging

Isocharge is best described as a hybrid design, crossing laminar flow technology with a glove box isolator. It provides the operator with the protection of a gloved visor and the flexibility of an open laminar flow booth providing a high containment solution for rapidly dispensing and charging powders into any process. The system is designed to feed powder from bags or drums into process equipment whilst managing all contamination risks for both operators and the environment.

Isocharge for bags

Isocharge for emptying bags consists of a stainless steel chamber which is open on one side, enabling easy loading of bagged powder. This principal feature allows powder to be loaded into the chamber and safely charged with the door open while achieving a high containment level of <1 µg/m3.

The open end is sized to provide an inlet air velocity of 0.7m/s; as the chamber size increases along its length, the air velocity steadily decreases until it levels out at approximately 0.2 - 0.3 m/s at the point of opening the bag of powder. This ensures that there is a one-way air transfer from the room, through the chamber, exhaust plenum, filters and fan, and finally out to the atmosphere.
