For this project, Rheo designed and built a custom hard-wall containment isolator tailored specifically for high-containment weigh and dispense operations. The isolator features a dual-chamber configuration engineered to optimize both operator ergonomics and process safety.
The first chamber serves as a low-profile antechamber, allowing for the safe introduction of raw material bags into the system. An interlocked pass-through door enables secure transfer of materials from the antechamber into the main dispensing chamber, maintaining containment integrity throughout the process.
The system control is managed via an Allen-Bradley touchscreen HMI, which automates pressure setpoints to ensure consistent performance. Materials are dispensed directly into a RheoPac positioned on an integrated bench scale. A weighing isolation bellows provides a sealed, flexible connection that preserves containment during the weighing process.
To maintain a consistently safe working environment, the isolator is equipped with an onboard, pneumatically powered Venturi blower unit featuring dual push-through HEPA filters. This system sustains negative pressure within the isolator during operation. Each chamber is supported by independent pressure control and filtration systems to further enhance containment and operational safety.
