High-speed decontamination tunnel for pharmaceutical Rtu material
Ensure 100% sterility of ready-to-use materials with a high-speed tunnel that achieves 6-log decontamination in seconds, seamlessly integrating into aseptic lines for continuous, efficient operations.

The NEBULA from IMA Group is a high-speed decontamination tunnel designed to solve sterility challenges in biopharmaceutical and pharmaceutical industries. Utilizing aerodynamic containment of highly concentrated vapour phase hydrogen peroxide, it achieves 6-log decontamination of RTU materials, such as pre-filled syringes and sterile vials, as they transit isolated production lines. Key to its operation is the seamless integration with IMA LIFE aseptic fill-finish lines, allowing continuous high-speed introduction of up to six tubs per minute. The tunnel’s design features pressure-managed chambers for operator and cleanroom safety, avoiding hydrogen peroxide circulation outside NEBULA. Compact at 3.7 meters in length, it requires 35% hydrogen peroxide solution, with a 6 liters per hour consumption rate, and offers easy size changeover independent of packaging. Compliance with GMP Annex 1 provides excellent assurance of sterility, and minimal layout impact ensures simplified production line integration.
