Extract Technology (ETL) recently supplied a turnkey sterile upgrade solution by offering a value-engineered Active Restricted Access Barrier System following the request for a controlled, aseptic environment for autoclave unloading and can filling.
Based on ETL’s experiences with aseptic and sterile isolator projects, the RABS was designed to provide a controlled aseptic environment, taking into account specific operator ergonomics which was of paramount importance for user friendly access to the client’s aseptic processes.
The active RABS designed and manufactured for this project followed a detailed and concise specification from the client. Key features included:
- Fully glazed enclosures, aiding operator access providing maximum viewing of all process operations
- Open areas in the base allowing air to return to the room
- Multiple/large glove port positions providing suitable ergonomic working positions
- PLC control system complete with HMI (HMI By Others)
- Hinge open access doors allowing for operator access into the enclosure
- Manual roller conveyor to aid the movement of the product from the trolley to the filling point
In addition to specific operator ergonomics, further key functions of the bespoke system also include a ‘closed loop’ control to maintain operating conditions within the enclosure at all times. The enclosures operate with a recirculatory airflow principle (via room return) with a dedicated supply airflow plenum providing vertical laminar flow (0.45m/sec) within the enclosure achieving ISO 5 – EN ISO 14644-1 (1999), assuring that proposed aseptic level protection and technical specifications are met.
