Depyrogenation tunnels for pharmaceutical containers
Ensure precise sterility and safety in pharmaceutical production with advanced depyrogenation tunnels, designed for high-speed continuous operations that optimize the washing, sterilization, and cooling of ampoules, vials, and larger bottles.

Sterilizes and Depyrogenates Pharmaceutical Containers
The DEPYR Depyrogenation Tunnel from Marchesini Group is an advanced solution for pharmaceutical and biotech industries, specifically designed to sterilize and depyrogenate ampoules, SVP vials, and larger bottles. Its fully integrated dry-heat sterilization system uses dedicated resistors and separate air loops for efficient cooling and sterilization, minimizing downtime and energy consumption. The symmetrical air recycling ensures consistent temperature distribution, while automatic pressure compensation guarantees precise process control and repeatability. With a handling capacity determined by the tunnel size and container type, DEPYR operates continuously at high speeds, ideal for large-scale production. Constructed with tubular stainless steel and equipped with easy-access panels, it supports GMP compliance and efficient maintenance. Optional customizations and engineering support are available to meet specific operational needs, ensuring seamless integration into existing production lines.
