Features and Design

• Hygienic Design: Designed to prevent bacteria build-up and facilitate easy cleaning.
• CIP-friendly: Minimal crevices and dead space for efficient Clean-In-Place processes.
• Closed System: Prevents ingress of foreign particles, ensuring product quality and safety.
• Hygienic Sealing Box: Modular design with O-rings in EPDM, Viton, or other EC 1935/2004 compliant elastomers.
• Scraper Systems: Available with rotating PEEK scraper knives or linear single/double-acting PEEK scrapers.
• Optional Sluice System: Features 2 drain valves to reduce media loss and prevent pressure drops.
• Optional Heating Jacket: Maintains a fixed media temperature for product quality and process flow.
• Extended Cylinder: In linear cleaning applications, the piston rod does not contact the media, preventing cross-contamination and bacteria build-up in the pneumatic cylinder.
