Surface Technology for Pharmaceutical & Biotech Systems
Engineer-led GMP surface treatment for pharmaceutical and biotech process systems: built as a compliance program, not a one-off service.
Derouge, Passivation & Surface Treatment
The Catinox division provides engineer-led, GMP-compliant surface treatment for pharmaceutical and biotechnology process systems, covering fixed installations (water-for-injection loops, clean-steam systems, process skids, storage tanks) and components, fittings, and small parts. Services include rouge assessment and classification (Type I, II, III), chemical derouge using pH-neutral chemistry, repassivation, CIP cleaning, descaling, derusting, and ultrasonic cleaning; all documented to validation-grade standard. Certified ISO 9001:2015 and ISO 14001:2015.
What sets Catinox apart is its origin: the team has specified, designed, and commissioned the same GMP systems it now services, so it understands exactly what your quality team will ask for. The model is built around a compliance program, not a one-off visit: establishing your system's baseline, supporting risk-based monitoring, and treating on schedule before rouge becomes a deviation or inspection finding. As an integrated Catalyst Group division, these capabilities connect directly into commissioning, qualification, and ongoing operations programs.
