Ceramat Overview

This patented retractable fitting with a ceramic sealing system is designed to handle challenging applications where conventional O-ring seals fail. The unique lock-gate principle uses two planar ceramic disks that rotate towards each other, effectively separating the calibration chamber from the process. This ceramic seal is harder than steel and highly resistant to chemical, thermal, and mechanical influences, ensuring maximum availability and process safety.

Key Features:

Maximum Process Safety:

  • The process-wetted outer housing (available in PVDF, PEEK, steel, Hastelloy, or titanium) remains static, avoiding mechanical stress and enhancing durability.

Maintenance Without Process Interruption:

  • The innovative design allows for easy on-site maintenance. The entire drive unit can be removed under full process conditions, keeping the process medium isolated. Even if the sensor breaks, the calibration chamber can be cleaned without halting the process.

Versatile Applications:

  • Suitable for highly corrosive processes (e.g., chlorine production, phosgenation), processes with depositing, abrasive and incrusting solids (e.g., flue gas desulfurization, gas scrubber), pulpy and fibrous media (e.g., cellulose, cosmetics), organic and sticky residues (e.g., refinery wash water), and processes involving highly toxic substances (e.g., phosgene gas, hydrogen cyanide).
