Why Polished Vessels Are Essential for Clean Steam Generation
Clean steam must be free from contaminants, particles, and endotoxins for critical applications. Polished vessels deliver:
- Ultra-Clean Surfaces: Electropolished interiors prevent particle shedding into steam
- Reduced Biofilm Formation: Smooth surfaces minimize bacterial attachment and biofilm growth
- Minimal Corrosion: Highly polished surfaces improve corrosion resistance and prevent metal contamination
- Enhanced Passivation: Superior passive layer formation protects steam purity
- Regulatory Compliance: Meets pharmacopeial and industry specifications for clean steam
