Features of our sterilization tunnels



Our modular tunnel series uses dry heat to sterilize a wide range of containers safely and reliably, including pre-cleaned ampoules, cartridges, and syringes using the unidirectional airflow principle. The proven temperature treatment makes sure the containers are sterilized in a fully definable and validatable way, which increases process safety and treatment quality. In addition, the HQL sterilization tunnels are highly flexibility and cost-effective thanks to their modular set-up and high level of automation.

• Proven dry-heat sterilization (UDAF principle)
• Gentle container handling via automated transport system
• Automatic filter scan
